Thermal vapor is a useful household appliance invented not so long ago. It combines the functions of an electric kettle and a thermos, and is in many ways similar to a samovar. On the one hand, it allows you to quickly boil water, on the other - to maintain its temperature for a long time. However, such household appliances from time to time need repair. If you want to repair the thermopot yourself, before starting work, learn as much as possible about how this device works and functions. To do this, read the instructions attached to the device.
The device and principle of operation of the thermoscale
All heating devices are arranged according to one scheme, they are distinguished only by the additional functionality and the material from which they are made. The functional elements of the device are placed in a protective case, so in order to fix the thermal flute with your own hands, you will need to remove the case. The liquid flows into a stainless steel tank, into the bottom of which two heating elements are integrated - heating elements. The first carries out heating of the liquid to boiling water, and the other heating elements are needed to maintain the temperature. All cables are equipped with a protective coating made of ceramic, which prevents the cables from contacting the steel tank.
In the side there is a tubular object( water pump).This pump is needed for water supply. In various versions, the voltage drop at the motor is in the range of 8-24 V.
It is worth noting the electrical board on which the circuit is installed, which is necessary for secondary boiling. In addition, it is necessary for voltage conversion. Broken contacts on this board can be repaired with your own hands, just using a soldering tool.
In addition to this main board, the device also has a control module. It supports the operation of the water supply keys and secondary heating. Also connected to the module are indicators that show which of the available modes the technician is currently working on.
In the heating device, the thermostat is of great importance. It is mounted in the bottom or side of the water tank. For situations where the thermostat for some reason does not work, a thermal fuse has been created. It eliminates the possibility of overheating and breakage of the thermal steam when it is accidentally activated with an empty tank.
Finding out where all the key elements of the thermotube are located, it becomes substantially easier to establish the cause of the breakdown and repair the thermopot with your own hands. But it would be more correct to investigate the scheme, to understand all the connections and what parts are to be replaced. In some cases, repair is inappropriate, and even experts do not take it.

Thermots Consider the most common problems and how to fix them.
- The indicator panel does not light up and the device does not function at all. In such a situation, it is necessary to inspect all wires and connections, as well as the thermostat and fuse. If there is more than one breakdown, it will be more difficult to repair the device with your own hands.
- Only the secondary boiling key functions, but the main primary boiling is not performed. In such a situation, a thermal switch located in the bottom is tested.
- The main boiling works, but with the secondary one, the thermal steam does not work. It is necessary to examine the module on the main board.
- Boiling does not work, only heating is available. Most likely, the heating component burned down, or the wire broke.
- Water supply not working. There are violations in the pump. Often at the same time the spiral element for auxiliary heating burns, after which the voltage is not supplied to the engine.
Faulty network cable thermopota
The housing of the vehicle is fastened with screws, which need to be unscrewed, having previously removed the plug from the socket. In the inner part you will find the bar to be carefully examined. All kinds of burnt parts, without a doubt, point to the specific location of the fault. The cord is carefully separated from the device and checked by a tester. If the cause of the cable is faulty, you can quickly replace it with your own hands.
Chips
In the standard thermo sweat there are two electronic modules:
- For power supply.
- to manage.
Both need to be visually inspected if there are no swollen capacitors, blown resistors, unsuitable fuses, broken tracks. Replace damaged elements with new ones; contacts and soldering are restored by tin plating.
But first of all it is necessary to check the presence of fuses and their integrity. If a component change does not help, but instead the replaced part also burns, then the fault lies in the electronics that went down due to a short circuit.
Resistors are indicated by multi-colored stripes. The standard question is how to find out from which side the labeling begins and from which side it ends.
With capacitors much easier - they swell. As a rule, newcomers who are looking for methods of repairing a thermosol are tormented by the question - what does it mean to “swell”?To understand, it is enough to see a broken capacitor at least once.
With diodes is always more problematic, however, and they break much less. You just need to separate the component and test it with a tester from both ends to find out if it works.
Torn tracks of the electronic circuit should be slightly cleaned, removing the paint layer from them. Then the surface is tinned and covered with solder. Will work as well as before.

The pump does not work
The pump pumps water for feeding through a crane in manual or automatic mode. The pump is quite simple, it includes several simple windings that any beginner can understand. All contacts must be called in pairs. Also, the pump, dismantled from the case, is worth testing, sending a certain voltage to it. The 12 volts needed to test the pump can be obtained from simple batteries or a car battery.
Repair of heating elements of thermosweat
We do not recommend replacing metal sheets with terminals for others. Overheating protection is provided by bimetallic switches. The durability of the device largely depends on the functioning of this element. As a rule, there are more than one thermal switch in the heating element, one of which controls the characteristics of the liquid, and the second does not allow activation when the tank is empty. In such a situation, the component of heating elements heats up to a temperature of more than one hundred degrees and breaks the power supply circuit.
To improve the contact of the circuit breakers, use a special paste, similar to the one that is applied between the fan and the PC processor.
This sensitive component functions quite simply. When the surrounding space warms up to the set temperature, the contacts of the circuit breaker switch open. But as soon as the temperature decreases by 15-30 degrees from this point, as the conductivity resumes. Unfortunately, it is impossible to figure out what type these elements of heating elements are related to, simply by looking at the instructions of the thermoplot. However, the surfaces of the elements are always labeled, so you can choose the optimal replacement.

As a rule, the manufacturer is not satisfied with the simple system of protection against overheating and equips the equipment with fuses. These are small tubular elements, closely attached to the wall of the tank or glued to it. When the steel tank heats up to a critical temperature, the fuse of the heating element will burn, and the device will not work unless it is replaced. That is why you should carefully examine the technique in terms of the presence of such defects.
Also, with the help of a tester, the operability of the bimetallic contact is checked. Before starting the test, the element of the heating element should be evaporated.
When spirals of heating components burn, repairing equipment is simply unprofitable. The tank is too complicated for self-parsing, and the insulation and cables are quite expensive.
After the completion of repair work, the safety of the device should be tested. To this end, determine the resistance between the plug and the tank, and between the plug and the outer case. In a normal situation, it must be infinite.
