The principle of operation of a power regulator on a triac. Power regulator with phase controlled triac on PIC16F84A. Let's figure out how our specific thyristor power regulator works

Today, in many areas of human activity, various technological devices occupy a priority place. The cooking industry also has many engineering innovations to make our lives easier.

Surely, in many people’s kitchens you can find not a simple electric kettle, but a thermos or a so-called “thermal pot”. This word came from in English and literally translated means a temperature pot or thermos.

Advantages and disadvantages

The main advantage of a thermopot over electric kettle is that you can not only boil water in it, but also store it, maintaining high temperature like in a thermos.

You can set the temperature yourself. Most models are equipped with four water heating modes. It is able to maintain the temperature you need for several hours.

The water remains hot, as if it had just boiled, but if you need to, you can select a mode with lower values. By purchasing a thermopot, you will always have water at the required temperature in stock, for example, for brewing a cup of tea or cooking baby food for a child.

In addition, this device can save not only your time (you do not need to wait for the water to heat up), but also electricity (you do not need to turn on the electrical appliance every time someone in the household wants to drink hot tea or brew porridge or other food) .

Minuses:

  • A large amount of liquid, four to five liters, will take longer to boil than in an electric kettle.
  • Its cost is several times more than a simple electric kettle.

Causes of failure

From this video, you will learn what causes of failure of thermopots. We recommend viewing!

Despite the fact that such devices have an excellent and durable design, they break quite often due to the poor quality of their electrical components. Since the cost of a new kettle like this is not small, in many cases it is best to repair it yourself or by contacting a specialist and not overpay a significant amount of money to purchase a new kettle.

The main reasons why this unit may fail, as well as methods for eliminating them:

  • Lack of indication of the special thermopot control panel does not turn on. It is necessary to check the integrity of all wires, and also check the operation of the thermal fuse and safety switch.
  • The thermopot's re-boil button does not execute the command and does not boil water when it is first turned on, or when water is poured into it. It is necessary to check the operation of the thermal switch located at the bottom of the tank.
  • The device does not work in all modes. With this problem the electrical diagram forced boiling actually breaks such parts as a relay, a transistor or a rectifier.
  • Failure to operate the water supply lever. Most likely, the water supply motor or the rectifier diodes on the motor power supply circuit are faulty. This is a list of the main thermopot malfunctions, which have a similar design.

Repair of various thermopot parts

    • Power cord. To repair the power cord, you need to unscrew several screws to which the thermopot body is attached. There is a special block inside, and visually inspect all internal parts. We carefully separate the cord and check it with a tester; if it is faulty, we replace it.
    • Chip. An ordinary thermopot has two microcircuits: a power supply and a control one. We inspect them visually in order to identify swollen capacitors, burnt transistors, broken fuses, and other damage. In order to replace elements that have failed, it is necessary to use soldering; it does not restore contacts according to the methods presented. Initially, when repairing a microcircuit, you need to see if all the fuses are in place and whether they are intact. If you replace the fuse, but the thermostat also does not work, the cause of the failure consists in its electronic filling. Because there was a short circuit in it.
    • Capacitor. It is much easier to deal with a broken capacitor. Since they swell and are easily identified by appearance.
      Diodes. It is much more difficult to determine the failure of diodes; the good news is that they break quite rarely. It is necessary to sample the element and call its sides to understand whether it is in working condition.
    • Board tracks. In order to bring the torn tracks on the board into working condition, they are lightly cleaned with sandpaper and made from them upper layer varnish The shiny surface is combined and covered with a layer of solder.
    • water pump. Also, each device contains a special pump for supplying water, both automatically and manually. For a Vitek thermopot, a new pump costs about $30; an experienced electrician can easily determine which part is faulty. It is also necessary to check the suitability of the thermopot pump.

Repair of heating elements

If heating elements break down, in almost all cases they must be replaced. New heating elements start at $40. The standard device contains several thermal switches.

One is designed to control water parameters, and the second serves to protect against turning on the device if there is no water in it. The thermal switch works in such a way that the surface of the tank and the flange are in contact.

To improve contact, a special lubricant is used, similar to that used in personal computers. When a certain temperature of the switch is reached, its contacts close; as soon as the temperature decreases, their conductivity is restored.

These thermopot components can be easily found, since their description is written on the body and marked accordingly.

. More detailed information, you will find on our website.

This article will tell you what features the Karcher vertical clothing steamer has, don’t miss your chance to get acquainted with useful material!

You can find a description of a portable gas tent heater.

But most often the manufacturer also adds an additional temperature fuse; it is a small cylindrical part that fits tightly to the wall on the bike.

It works exactly the same as a regular thermal switch. In order to check the operation of the metal contact, it is necessary to perform a dial test by first making the working contacts short-circuited from the thermopot.

The internal filling of most thermopots is slightly different from each other. And the simplest models are easy to repair yourself. Repair of the Vitek thermopot can be carried out according to standard schemes. To repair this device on your own, you must soberly assess your knowledge and experience.

And do not try to solder microchips with an unsuitable soldering iron that require a hot air gun. First you need to know the basic techniques for working with electrical components, which often fail static electricity and high temperatures.

In order to make repairs, you will need tweezers, a tester, a screwdriver with a voltage indicator, as well as a soldering iron and other tools.

The thermal kettle, or thermopot, is gaining immense popularity. However, its cost is quite high, so to save money, you can fix some problems yourself. It often happens that the thermopot heats the water, but does not boil it.

Causes of malfunction of thermopots.

Before you start looking for the reasons for the breakdown of the thermal kettle, you need to know what kind of item it is. A thermopot is an electric kettle that includes a thermos function and consists of two bodies. The outer one is usually made of plastic, and the inner one is made of metal. The inner housing contains a water flask. The kettle is closed using a lid on which the entire control panel is located.

To fix any breakdown of the thermopot, the first thing you need to do is check that the settings are correct. In its settings menu you need to set exactly the water heating temperature that is needed. If everything is in order with the heating settings, then the reasons for the breakdown may be:

  • thermal switch located on the bottom of the kettle;
  • thermal fuse located on the wall of the thermopot;
  • insufficient contact of any component connectors;
  • electronic board malfunction;
  • The indicator panel stopped turning off. There are times when, on the contrary, the indicator panel turns on, but the thermopot does not start. If this is the cause of the breakdown, then it is worth checking all its components, wiring and thermal fuse.
  • The kettle stopped turning on. To eliminate this malfunction, it is necessary to check the correct operation of the electrical circuit and temperature switches.

In order to more accurately identify the cause of the gadget’s breakdown, you will have to disassemble it.

How to properly disassemble a thermopot

  1. The first step is to remove the top cover, as it will get in the way. The next thing to do is turn the device upside down and use something flat and sharp to remove the corkscrew ring, such as a screwdriver or knife. To perform this action, it is worth using some physical force.
  2. Several screws will appear under the corkscrew ring; they can be easily unscrewed using a shaped screwdriver.
  3. The next step is to remove the bottom of the kettle using a knife or flat screwdriver, which requires little effort, because the bottom is secured with latches.

After that, all the electronic stuffing is before your eyes. Now you need to check all the terminals for connection strength.

Important! In order to properly disassemble a thermopot, you must have at least a little knowledge of electrical engineering!

Minor damage to the kettle may occur. In such cases it is possible.

Reasons why the thermopot does not boil water

Thermal switch failure

Thermal switches are located on the walls or bottom of the thermopot. This part is attached to the main body with bolts from which contact wires extend. In order to maintain heat exchange inside the vessel, the mounting points of the thermal switches are coated with a special white compound. In order to remove it, you just need to disconnect the thermal switch contact and pull it out. In the quiet position the switch will be on. You can check its serviceability using a special tester (its readings should be equal to 0). You need to screw two wires to the thermal switch and lower it into boiling water. At this time, its resistance should increase, and the tester should show an infinite number - such readings indicate the serviceability of the part. If the tester readings do not budge, then you need to replace the thermal switch with a similar one.

Important! Before purchasing a thermal switch, consult an electrical professional or store salesperson.

If so, then you should pay attention to the thermal switches. Most likely, one of them will have to be replaced.

Malfunction of two spirals

Any thermopot has two heating coils, each of which performs its own function. The first is intended for boiling water, and the second constantly heats the contents of this unit.

If the thermopot breaks down due to a malfunction of the heating coils, then there is no point in repairing it. This event will take a lot of time and family budget. If there are a huge number of defects, it is better to buy a new kettle, because replacing all the wires and the tank at the same time will cost a lot of money.

Important! Regardless of the manufacturer and volume, each thermopot is equipped with several heating modes, with the help of which anyone can set the optimal water heating temperature for themselves.

But experts advise purchasing thermopots that have no more than three heating modes, since this is quite enough for optimal use of the device. The cheapest models of thermos kettles have one water heating mode. This feature should be taken into account when purchasing a thermal kettle.

Why doesn't the thermopot heat the water?

The main problem of any thermopot is heating the water. Often the reasons are some short circuit in the circuit that includes the heating element. Short circuits can occur in the heating element itself, relays and fuses. The easiest way to find out is to “ring” each element, as well as all wiring, using a multimeter. Using this method, you can easily find out which part requires replacement or repair.

Thermal fuse malfunction


So what role does the thermal fuse play in the operation of the electric kettle? This spare part is one of the most necessary in the device. It protects the device from combustion. If at least one of the fuses stops functioning, then the water stops heating.

Usually these parts are attached to the side walls of the thermopot. But in some models they can be installed on the bottom, and their appearance resembles small cylinders. They start working when the water temperature reaches boiling point. Their role is to turn off the device if there is not enough water in it. If the thermal fuses start to operate before the water boils, this can lead to overheating of the thermopot, and it will not boil, but simply heat the water. To check the serviceability of this device, it must be placed in boiling water. And if it turns on before it boils, it will mean that it is faulty and needs to be replaced.

Repair of thermal fuses.

It is necessary to check all the main components of the device with a multimeter. Testing the thermostat. To do this, you need to set the tester to a mode that allows you to measure resistance.

Multimeter shows complete absence resistance, this means that the main reason why the thermopot does not heat the water is precisely this. This means that the sensor must be replaced with a new one. To replace it you will need a shaped screwdriver. With its help, you need to unscrew the bolts that secure the sensor and replace it with a working one.

Important! It should be remembered that the constant temperature of the thermal fuse in working condition is about 90 0 C.

If after changing the thermal relay in normal mode, it means that the efforts were not in vain and the repair was completed successfully.

Thermopot was invented very recently. After boiling water, the kettle does not keep it hot for long. It is the thermopot that helps maintain the water temperature for a long time. You can always drink tea, and you don’t have to boil it and wait. But, like any technical tool, the thermopot breaks down and has to be repaired. How to do it yourself later in the article.

IN old times Thermal pot would have been called a samovar, now it is affectionately called a potter. It can not only boil water, but also keep it hot, like a thermos. But if your Potter breaks down, you don’t have to call a technician and take it in for repairs. You can do the work yourself. Before using each household appliance, you must read the instructions. Understand how to use the item correctly and what will prolong its use. For example, with a thermopot, according to statistics, the following often break down: the indicator panel, the primary boiling key, the secondary boiling key, the boiling function and the water supply.

All these breakdowns occur due to the influence of high temperature on all elements of the device. For example, the housing that protects the entire device should not heat up when boiling.

These thermopots are very popular: Polaris, Vitek, Elenberg, Scarlett and Alice. The thermopot circuit is simple enough that a non-professional electrician can figure it out. But all the same, a scheme is a scheme, and it is not recommended to get into it without minimal preparation. Therefore, if a thermopot does not boil water at all or does not perform the functions of a thermos, then first you need to examine its circuit and understand the principle of operation.

Thermopot operation diagram:

  • All elements are located under a protective housing;
  • The water tank is made of stainless steel;
  • Heating coils are installed at the bottom;
  • One spiral heats the thermopot, the second maintains the water temperature;
  • The thermopot pumps water using a water pump.

The thermopot works as follows: after pouring water into the thermopot itself, the lid closes and the device turns on. One spiral begins to boil water. The thermal fuse turns off the product as soon as the water reaches required temperature. The water cools down to the desired temperature set by the user. The temperature itself is maintained by a second heating element. Thermal fuse is recommended to use Sheng Ping SPF 139 reusable. Therefore, if a thermopot breaks down, you will have to completely disassemble it, remove the cover with the button, check the heating element and determine why it broke.

Products from different manufacturers have their own characteristics. For example, the Vitek device has a special button for drawing water into a cup. This button is also called a pump or pump. With it you can type hot water into a cup without getting burned. The circuit board for the Vitek thermopot is called RSP22, it is available and easy to make in special services.

Quick thermopot repair: frequent breakdowns

If the thermopot constantly breaks down, then you need to take it in for repair or deal with the problem yourself. It is better to start repairing the kettle by disassembling the body, removing the lower plastic part, and unscrewing all the bolts. After this, access to all electronics opens. The electrical component of the product is open to fault detection. The fundamental importance is to repair the thermopot after full analysis. Having assessed all the components as described in the instructions, you can determine the reasons for the breakdown - perhaps the stainless steel tank has broken.

Reasons why the thermopot does not work:

  1. The indicator panel does not turn off. The opposite also happens, a complete lack of operation of the device and the indicator panel. In this case, you need to check all wires and contacts. Check the boiling regulator.
  2. The main switch doesn't work. Check all temperature switches and whether the electrical circuit of the switch located on the bottom is working correctly.
  3. The water is heated, but not boiled. When boiling is turned on, the thermopot turns off and does not perform its main boiling function. In this case, the contact is checked for rupture or the part is completely boiled.

If the thermopot does not heat due to the breakdown of 2 spirals, then there is no point in repairing it. It will take a long time and a large amount money. If there are many defects, it’s easier to get a new one, because repairing the wiring and tank will be expensive in total.

Primary help: when the thermopot does not boil water

The most important thing is to check the settings on the control panel. Perhaps the boiling function is turned off, and the thermopot turns on only in heating mode. Then it turns out that there is no malfunction, which means there is no need to eliminate the broken part. The settings are fine, but the water does not boil - check the temperature sensor and heater. If the elements do not work well, they must be replaced with new ones.

How to disassemble a thermopot:

  1. Remove the top element – ​​the cover. Then remove the ring securing the inner tank to the housing.
  2. Remove all fastening elements - screws and bolts.
  3. Remove the bottom of the thermopot.

For all these manipulations, a screwdriver is useful. To get to the electronic filling of the device, you need to remove all the elements, and only then can you repair the device. Thermal pot can perform many functions, for example, replace a thermal mug. But what good is this if the water there is not boiled - you can’t make tea or coffee.

But, before you disassemble the device, you need to know exactly where everything is attached and how many parts were there before disassembly.

Thermal switches have a boiling function. They are usually located at the bottom of the product or along the walls. To prevent the thermal switch from melting, it is treated with a special solution. To check the element for operation, you need to pull it out and leave it on, screw the wires to it, and place them in the water. With all this, you need to check the resistance. It should not be outside the water; if it increases in water, it means the part is working and the breakdown is not in it. If everything is the other way around, then the thermal switch is faulty.

Replacing the pump if the thermopot does not pump water

It happens that the thermopot works, boils, heats and keeps the water warm as long as necessary, but it is impossible to pour water - the valve is broken and water supply is impossible. And it’s not at all clear which option is better: a broken heater or a supply function. Such a breakdown indicates a malfunction of the pump (pump) for pumping water into the mug. Then it is necessary to disassemble the machine and examine the suspicious element.

How to get to the pump:

  1. After removing the metal casing, disconnect the tubes from the pump. If you find scale on the wires, you need to get rid of it.
  2. Disconnect the pump itself from the tank and housing, while trying not to lose all the small parts.
  3. As soon as the pump and the electric motor are disconnected, remove all scale that interferes with the proper operation of the device.

Like anyone household appliance, the thermopot needs care and maintenance. You can descale it at home using citric acid, acetic acid and baking soda. The thermopot should be cleaned immediately, as soon as the first scale appears. If the product begins to make suspicious sounds, then cleaning is all the more necessary. This is the first signal for help.

If after all these manipulations there is no water supply, then you need to change the pump itself - buy a new one. There is no point in restoring a damaged pump.

Cleaning with soda and acid is carried out in accordance with the size of the product itself. You can also use special cleaning products, just carefully study the composition. Citric acid has its drawbacks - sometimes it is not enough for one kettle. But after boiling water with citric acid, it is important to then wipe the kettle with a soft cloth. There is no smell after boiling, you can combine it with vinegar. Acetic acid It removes scale instantly, but it’s very difficult to get rid of the aroma afterwards. It requires several boils after and cleaning with a special product, so it is better to clean with a mixture of citric acid and vinegar.

Do-it-yourself thermopot repair (video)

Thermopot is a very convenient thing for giving and relaxing. The water will be hot all the time; in cold weather you won’t have to constantly run to the stove and put on the kettle. You can just go up and pour some hot water, it makes life easier and reduces wasting time. By installing a thermopot in the morning, after a shower, you can immediately drink coffee without worrying about the kettle boiling and the water immediately cooling down.

The most common breakdown of a thermopot is a malfunction of the water supply button. There may be several reasons: wear of the mechanism, ingress of debris, mechanical damage. Whatever the reason, fixing the breakdown is quite easy. Let's look at how to repair the water supply button on a thermopot with your own hands.

Thermopot device

Thermopot is an innovative modern device that combines the functions of a kettle, filter and thermos. The prices for such electrical devices are relatively high, but are justified by the quality and durability of the product. However, even the most expensive equipment can break down.

Thermopot in working condition

Thermopot in working condition

Before talking about possible malfunctions and their causes, it is worth understanding the device. The main components of the thermos kettle are:

  • frame;
  • heating elements;
  • electronic board;
  • DC motor;
  • control board;
  • thermal switch;
  • thermal fuse.

Bottom thermopot panel

To inspect the internal parts of the device or repair it, the first step is to remove the housing. It can be ceramic, glass, plastic or metal. Sometimes there are thermopots made from combined materials. The shape of the water tank can be semi-cylindrical or rectangular. Regardless of this, the disassembly scheme for the device is the same for all models.

In the lower part electrical device heating elements are placed. They can be either disk or spiral, similar to an electric kettle. However, a thermopot is always equipped with two heating parts: one brings the water to a boil, the other maintains constant temperature in the device. Practice shows that spiral thermal kettles fail more often than disk ones. Therefore, the second type is considered the most optimal choice.

Thermopots also differ in power, which determines the speed of heating water and maintaining a stable temperature regime(from 60 to 90 degrees). The range includes devices with a power of 600-2000 W.

Disassembled thermopot

The thermopot is considered a completely safe electrical appliance for children and very convenient for use by pensioners, since it does not need to be lifted and tilted to pour water into a cup. It is equipped with a special element for supplying water - a pump. This part comes in two types: electrical and mechanical. Water begins to flow into the cup after pressing the “Water Supply” button, which can very often be associated with thermopot malfunctions.

Frequent thermopot breakdowns

The following inconsistencies in the operation of the device may indicate a breakdown of the thermopot:

  1. The device does not turn on, the indicators are not illuminated.
  2. The main boiling does not function, only heating is turned on.
  3. The heating does not work, but the main boiling functions as it should.
  4. There is no water supply.
  5. The water takes a long time to heat up, while the thermal kettle itself quickly turns on and off.
  6. When heating, the device makes a loud noise.

The cause of the problem electrical engineering This purpose can include such parts as: heating elements, electrical cords, capacitors, diodes, microchip, microcracks on the board and many others. etc.

After some time of operation, the thermopot begins to slowly bring the water to a boil. In this case, the malfunction may be due to excessive scale formation. This problem is usually eliminated with the help of special products that can be bought in stores, or by using a homemade citric acid solution.

It happens that water gets on the device itself, after which problems begin, which may indicate failures in microcircuits and boards. It is recommended to check the boards for microcracks and burns. It is not recommended to solder any elements, especially with an inappropriate soldering iron.

If the device stops boiling water, the first thing you need to do is check the heating elements; the heating element may have failed. To start special tools you need to ring all the parts that are responsible for boiling water. But experts do not recommend replacing burnt heating elements, as the pricing policy shows - this is not at all cost-effective in this case; it is better to buy a new electrical appliance.

New thermopot

The backlighting of the indicators may be the result of a malfunction of fuses, thermal switches or the power cord. The cord of the device must be checked together with the connector, which is located inside the case. It needs to be tested with a multimeter and, if unusable, replaced with a new one.

What to do if the water supply button on the thermopot does not work

The control panel of a thermal kettle usually has two buttons: one is responsible for supplying water, the other for heating. Non-functioning of the first may indicate serious damage to the electrical device. When the water supply button on the thermopot does not work, you can think about a malfunction in the pump’s power supply, a burnt-out coil, as a result of which the voltage supply to the motor is stopped.

If the device does not work when you press the “Water Supply” button, try moving it; suddenly appearing water may indicate that the cause is the contacts.

Thermopot control panel

If there are problems with the water supply to the thermal kettle, the pump of the electrical appliance is dismantled and all its components are checked:

  • connecting tubes;
  • supercharger;
  • electric motor;
  • the buttons themselves, which are located outside.

Connecting tubes require checking for dirt, scale, etc. The motor itself needs to be ringed using any external source with tension. Even the most suitable ones are suitable for this. regular batteries. Some technicians use a car battery. A breakdown of the device when the thermostat button does not work indicates that the electric motor, whose normal operating voltage is 8 - 24 volts, does not respond. In the case of a thermal kettle, independent repairs are not always worthwhile; it is better to contact a service center.

Dmitry Ivanov: Hello. There is such a problem. Thermopot After it was filled with water TO LEVEL and turned on, it began to boil. And then every 40-50 minutes it starts to boil again. What could it be???

first second: How many volts is the motor?

Vyacheslav Kablaev: I really liked the video! All in simple language and volumetric. And it’s clearer this way, even to the stupid me. Thank you! My + and subscription!

Aidar Khuzin: Hello, low pressure, what can I do? Washing didn't help(

Gray Fox: Hello, I have such a problem, the heating coil burned out, I took it apart somewhere, removed a couple of turns, twisted it, it started working, but... after boiling, the heating turns on and immediately lights up. The lock does not allow water to be poured, what is the reason?

Otto Dietrich: I press the Block button, then pour water. The pump jerks, the block button turns off. What could it be

Urzhum: Apparently the bottom of the owner's thermopot scooped up water in the sink. They turned it on without waiting for the water to dry. As a result, the transistor short circuits and fails. The instructions must be read at least once from cover to cover, there is a warning about what to avoid. Many have not had a single breakdown even after 7 years of operation. The coating peels off over time - because it is poured cold water into the hot bowl of the machine. There is zero attention to this, the mesh filter delays the delamination, it must be monitored and removed from the mesh.

Nader Ibeidou: Very useful video…..thank you very much

Tanks are not afraid of dirt.: Hello. I have a Chinese thermopot from METRO-Cash&Carry, no name, some kind for sale only in Metro. 4.2 l with electric pump. IN Lately After filling the mug with boiling water, the boiling heater began to turn on for a few seconds. What could it be? Have you encountered such a defect?

Damir Akhmetov: Hello Oleg, tell me. The thermopod is a new Chinese-made model “Tiffany”, it has a “water supply” button. But there is no “reconnection” at all.. there is a place on the board.. but there is no button itself.. is this how life should be or what do you say? ??

MoOvik: By the way, while doing this, I changed the diodes from 1000V to 400V, the rest of the characteristics are the same, what are the consequences?

MoOvik: but I didn’t have a tester nearby, I watched you check the motor and it started and now I have a 12V power supply from the kettle))

Sony Bravia:!!! I have a similar Panasonic NC-EM40P thermopot, it stopped boiling water and only works in heating mode. The contacts of the heating element rang at 3:30, yellow - orange are ringing, but yellow - red are not. I tried to find it in workshops, but there’s nothing at all anywhere, probably they don’t supply heating elements, now I’m racking my brains about what to do, it’s a pity to throw it away. Maybe you can tell me something?..

Mohd Rizal kamal: Hi there, can someone speak in english.. i would like to know how did you test the dynamo(pump)? …are u using battery or using electric?

Sony Bravia:!!! 5:12 Mine’s inner covering has also peeled off, and now the heating element has also burned out, I don’t know where to get it... (((

Pyotr Starygin: Hello, please tell me, the heating boils and does not turn off

Andrey Malinovsky: Can you tell me what the operating voltage is for the pump motor?

Kirill Stadnik: On the contrary, it pumps without interruption - what do you recommend?

    The main advantage of a thermopot over an electric kettle is that you can not only boil water in it, but also store it, keeping it at a high temperature, like in a thermos.

    You can set the temperature yourself.

    Most models are equipped with four water heating modes.

    It is able to maintain the temperature you need for several hours.

    The water remains hot, as if it had just boiled, but if you need it, you can choose one with lower settings.

    By purchasing a thermopot, you will always have water at the required temperature, for example, for brewing a cup of tea or preparing baby food for your child.

    In addition, a thermopot can save not only your time (you don’t need to wait for the water to heat up), but also electricity (you don’t have to turn on the electrical appliance every time someone in the household wants to drink hot tea or brew porridge or other food.

    A large amount of liquid, four to five liters, will take longer to boil than in an electric kettle.

    Its cost is several times more than a simple electric kettle.

    Causes of failure.

    From this video, you will learn what causes of failure of thermopots. We recommend viewing.

    Despite the fact that such devices have an excellent and durable design, they break quite often due to the poor quality of their electrical components.

    Since the cost of a new kettle like this is not small, in many cases it is best to repair it yourself or by contacting a specialist and not overpay a significant amount of money to purchase a new kettle.

    The main reasons why a thermopot may fail, as well as methods for eliminating them.

    Lack of indication of the special thermopot control panel does not turn on.

    It is necessary to check the integrity of all wires, and also check the operation of the thermal fuse and safety switch.

    The thermopot's re-boil button does not execute the command and does not boil water when it is first turned on, or when water is poured into it. It is necessary to check the operation of the thermal switch located at the bottom of the tank.

    The device does not work in all modes.

    With this problem, the electrical circuit failed due to forced boiling and actually broke such parts as a relay, a transistor or a rectifier.

    Failure to operate the water supply lever. Most likely, the water supply motor or the rectifier diodes on the motor power supply circuit are faulty.

    This is a list of the main thermopot malfunctions, which have a similar design.

    Repair of various thermopot parts.

    Power cord. To repair the power cord, you need to unscrew several screws to which the thermopot body is attached. There is a special block inside, and visually inspect all internal parts. We carefully separate the cord and check it with a tester; if it is faulty, we replace it.

    Chip. An ordinary thermopot has two microcircuits: a power supply and a control one. We inspect them visually in order to identify swollen capacitors, burnt transistors, broken fuses, and other damage. In order to replace elements that have failed, it is necessary to use soldering; it does not restore contacts according to the methods presented. Initially, when repairing a microcircuit, you need to see if all the fuses are in place and whether they are intact. If you replace the fuse, but the thermostat also does not work, the cause of the failure consists in its electronic filling. Because there was a short circuit in it.

    Capacitor. It is much easier to deal with a broken capacitor. Since they swell and are easily identified by appearance. Diodes. It is much more difficult to determine the failure of diodes; the good news is that they break quite rarely. It is necessary to sample the element and call its sides to understand whether it is in working condition.

    Board tracks. In order to bring the torn tracks on the board into working condition, they are lightly cleaned with sandpaper and a top layer of varnish is made from them. The shiny surface is combined and covered with a layer of solder.

    Water pump. Also, each device contains a special pump for supplying water, both automatically and manually. For a Vitek thermopot, a new pump costs about $30; an experienced electrician can easily determine which part is faulty. It is also necessary to check the suitability of the thermopot pump.

    Repair of heating elements.

    If heating elements break down, in almost all cases they must be replaced.

    New heating elements start at $40.

    The standard device contains several thermal switches.

    One is designed to control water parameters, and the second serves to protect against turning on the thermopot if there is no water in it.

    The thermal switch works in such a way that the surface of the tank and the flange are in contact.

    To improve contact, a special lubricant is used, similar to that used in personal computers.

    When a certain temperature of the switch is reached, its contacts close; as soon as the temperature decreases, their conductivity is restored.

    These thermopot components can be easily found, since their description is written on the body and marked accordingly.

    Here. you can find a description of a portable gas heater for a tent.

    But most often the manufacturer also adds an additional temperature fuse; it is a small cylindrical part that fits tightly to the wall on the bike.

    It works exactly the same as a regular thermal switch.

    In order to check the operation of the metal contact, it is necessary to perform a dial test by first making the working contacts short-circuited from the thermopot.

    Repair tips.

    The internal filling of most thermopots is slightly different from each other.

    And the simplest models are easy to repair yourself.

    Repair of the Vitek thermopot can be carried out according to standard schemes.

    To repair this device on your own, you must soberly assess your knowledge and experience.

    And do not try to solder microchips with an unsuitable soldering iron that require a hot air gun.

    First, you need to know the basic techniques for working with electrical components, which often do not tolerate static electricity and high temperatures.

    In order to make repairs, you will need tweezers, a tester, a screwdriver with a voltage indicator, as well as a soldering iron and other tools.

    How to repair a thermopot with your own hands.

    All thermos-heaters have a similar design and operating principle, differing only in additional functions, as well as in the material of manufacture. The working parts of the thermopot are enclosed in a housing, and in order to repair the thermopot, it will have to be removed. Water is poured into a stainless steel tank, in the bottom of which two heating elements are built. One of them produces the main heating to boiling water, and the second only heats the water. There is also a general conclusion. Each wire is covered with ceramic protection - “beads”. This prevents the wires from coming into contact with the metal container.

    A cylindrical object can be seen on the side. This is a thermopot motor (water pump) designed to supply water. In different models, the voltage drop across the motor ranges from 8 to 24 volts.

    It is impossible not to notice the electronic board on which the circuit (time relay) is mounted, which is responsible for re-boiling. The circuit is also needed to convert voltage for the pump and relay. You can solder the detached contacts on the circuit with your own hands, thus repairing them.

    In addition to the main board, the thermopot has a control board. With its help, the water supply and reheating buttons operate, and red and LED indicators are connected to it, indicating which mode the thermopot is in.

    The thermal switch is of great importance in all heating devices. It is installed in the bottom and side of the water tank. In case the thermal switch does not work, a thermal fuse is also provided. This allows you to prevent overheating and damage to the thermopot if it is turned on empty.

    Knowing the location of all the main parts of the thermopot, identifying the problem and making repairs is much easier.

    It’s even better to study the diagram to understand what is connected and what parts can be changed. In some cases, repairs do not make sense, and even specialists will not undertake them.

    Let's disassemble the thermopot.

    It’s worth noting right away that it’s easiest to remove it with your own hands. top part thermos heater. To disassemble the thermopot, you need to find and unscrew the screws located at the bottom of the device. After this, the housing can be easily removed. First you need to visually inspect the board. It happens that a crack is discovered in the solder joint, and the soldered element falls off. In this case, you should use a soldering iron to secure everything as it was.

    Be sure to inspect the thermal switch located in the bottom. Its condition is checked with an ohmmeter.

    Do-it-yourself thermopot repair

    The working device has almost zero resistance. The non-working part must be replaced with a new one. And then the question becomes where to buy the necessary spare part. Often this can only be done through online stores.

    To remove the pump if it malfunctions, you need to disconnect the supply tube from it and unscrew the bolts. Sometimes cleaning the impeller and magnet with a regular napkin gives results. In some cases, repairs will no longer help, and you will have to resort to replacing the thermopot.

    How to fix some problems.

    Let's look at what malfunctions a thermopot can have and how to fix them yourself.

    The indicator panel does not turn on and the device does not work at all. In this case, you should check all wires, all connections, as well as the fuse and thermal regulator. If there are several reasons, then repairs will be more difficult to complete.

    Only the reboil button works. The main first boiling is not carried out. In this case, check the temperature switch located in the bottom.

    The first boiling works, but when boiling again, the thermopot does not turn on. You should inspect the circuit on the main board.

    The water can only be heated; the thermopot does not boil. Most likely, the heating element has burned out or the contact has broken.

    The water supply function has stopped working. There is a problem with the pump's power supply. Quite often, the additional heating coil also burns out, after which voltage is no longer supplied to the motor.

    If the heating element coils are burnt out, then it is not economically feasible to repair the thermopot. Firstly, it is difficult to disassemble the tank, and secondly, the cost of insulation and high-resistance wires is quite high.

    When the repair is completed, it is necessary to check the electrical safety of the device. To do this, it is necessary to measure the resistance between the plug contacts and the tank, as well as between the plug contacts and the outer casing. Resistance must be endless.

    Why does the water supply in the thermopot not work?

    All home appliances are created with the goal of providing comfort to the user. Getting used to convenient exploitation, we become upset when any feature does not function. Quite often, the thermopot's pump does not work. As a result, water enters the cup manually. It seems that the equipment generally works, but a minor breakdown makes it difficult to use the device. Today we will figure out why the water supply in the thermopot does not work.

    What to do if the pump does not pump.

    Work begins with dismantling the bottom cover of the device. Usually it is attached to several bolts that need to be removed. Then you should disassemble the pump; it will be more convenient to do this if you remove the supply tube. Next you need to check the condition of the connecting tubes. Namely, are they clogged with scale? If necessary, remove them and clean them.

    The next step is to remove the magnet from the engine. All parts must be thoroughly cleaned to remove scale and debris. This is best done with a napkin or cloth. When disassembling the pump and engine, do not forget to leave the gaskets intact. They will be useful when assembling the device.

    After these simple steps, the thermopot should supply water again. If the problem persists, you will most likely need to replace parts.

    The pump does not work and the temperature is not maintained.

    If the breakdown is complex, then look for the cause of the malfunction in the heating element. Most often this indicates overheating of the heating element. In this case, work begins with dismantling the top cover. Next we perform the following steps.

    Turn the thermopot over and remove the support ring. To do this you will need a screwdriver and a little effort.

    3. All the insides of the thermopot are hidden under the lid. We need to remove the upper part of the equipment body.

    5. The next step is to remove the heating element. It is important to proceed carefully here. The contacts can be released using a socket wrench, and the heating element tie can be released using a Phillips screwdriver.

    6. All that remains is to ring the heating element, replace it and make sure it is working.

    Be careful when replacing the heating element. Their size may vary depending on the model. For example, there are heating elements of 150 or 160 mm. Therefore, before purchasing, you should clarify what size is needed for your thermopot.
