How to check the TEN of a washing machine with a multimeter: ring the heating element
The heating element in the washing machine is one of the main parts. Outwardly, it resembles a small diameter metal pipe, inside which is a kind of spiral. It is heated by the action of current. This is due to resistance, which has a spiral. The free space inside the Tena is filled with a dielectric, which has a high thermal conductivity.
TEN in the washing process is often heated, and then cools down. The result is a spiral, located inside the metal tube gradually wears out and begins to lose its qualities. All this leads to that, that the heating element simply stops working. The part is either locked on the body, or burns out. Water is not heated during washing. If the TEN has become unusable, then the item should be replaced. It is simply impossible to restore the serviceability of the part. However, everyone will be able to check the washing machine with a multimeter TEN.
Where is the detail
In different models of washing machines, the heating element is located either in front, or behind. How to determine the location of Ten? If the back cover is large, that's where the heating element will be. Very rarely TEN is located in front.
You can also turn the washing machine on its side and look from below, where to be TEN. If necessary, you can remove the back panel of the washing machine. This will not cause much difficulty. It is enough to unscrew hardware.

How to calculate the resistance of Ten
To check the heating element in the washing machine, it is necessary to know not only, how to call TEN with a multimeter, but also an indicator of its resistance. First of all, this value should be calculated. You will need some information:
- High-voltage, which is fed to the water heater. In this case, the U is equal to - 220 V. This voltage, which is present in the household network.
- Power Ten - R. It will not be difficult to determine this indicator. Just look at the instructions. Knowing the model of the washing machine, the power of the heating element can be viewed online.
Having learned all the necessary indicators, you can calculate the resistance - R. There is a formula for this:
R = U2 / P
This resistance arises in Tene in the process of its use. The value of R in Ohms is measured. If the heating element of the washing machine is working, then the multimeter should show the resulting figure.
How to check TEN
After, as the location of Ten was determined, it is necessary to call the TEN for integrity. Before checking the heating element, many experts recommend removing it. However, this is not necessary. All you have to do is disconnect the wires from the heating element and ring it. To do this, unscrew all the nuts with a screwdriver or wrench. To ring the multimeter heating element, it should be de-energized and disconnected from the mains. Instrument, designed to determine resistance, should be translated to 200 Ohm. The ends of the multimeter must be attached to the Ten terminals.
- If the heating element is working, then the device will show the value, which will be close to the estimated.
- If the number is shown on the screen 1, then it indicates a break, which occurred inside Ten. In this case, you need to replace Ten.
- If the display shows 0, then there is a short circuit inside the heating element. Such damage can be corrected only by replacing the part.
Checking Ten for a breakdown on the case
If the multimeter shows the correct value, but the water does not heat up, then it is worth checking the breakdown of the part on the body. With this phenomenon, sparks may be observed under the appliance during the washing process. This is very dangerous. To check the multimeter should be switched to ring mode. The device should beep. After that, the indicators on the multimeters will light up. One end of the device should touch the Ten terminal, and the second - to the housing or to the ground terminal. If the multimeter started beeping, then the heating element is not working, and it needs to be replaced.
