How to check the resistance of the heating elements of the washing machine
Reasons why your the washing machine stopped heating watermaybe a few. First, it could fail control module. Secondly, there was a breakdown of the heating element - a tubular heating element. The most common cause of failure is the second problem. In the article we will tell where to find, how to extract, how to ring the heating element and check its resistance.

Testing the TENA
In order to make sure that the part is working, or, on the contrary, in its malfunction, it is necessary to do a few simple manipulations:
- Disconnect the washing machine from the power supply.
- Find the heating element, and it is located behind the front or back cover of the vehicle.
- Disconnect the wires from it.
- Check the resistance of the part with a multimeter.
- Visually inspect TEN for the presence of defects.
Where is the heater
To find the tubular heating element, we needdisassemble the washing machine. But first, let's determine where the electric heater is located in your unit. In most modern models, it is located behind the rear wall. But it is likely that your machine is not among the majority, and the part is located behind the front cover. To determine where the heater is, compare the walls, most often it is installed behind the one that is larger.
We dismantle the desired cover by unscrewing several screws. We find the heater, it is located at the bottom of the tank. Disconnect all wires from it.
We recommend to begin to take a picture of the location of all the wires, so that you do not have to randomly connect everything back.
Resistance
Before removing the heating element, it is necessary to check its resistance with a multimeter.The average value possessed by a properly functioning part is 24.2-40 Ohm. The voltage in the electrical network - 220 volts, squared, should be divided into a part power of about 2000 W (in our case).
The power of the heating element, which is installed in your washing machine,can learn from the instruction manual.
Before checking the resistance of the heating element, make sure that the washing machine is disconnected from the power supply. Next, start the test mode in the tester, set the value to 200 Ohm, hook the test leads to the terminals of the part. The result should appear on the display of the multimeter.
If the figure is close to the one given by the formula, it means that the heating element is all right. If the indicator is significantly less than the value that is considered normal, it indicates that the electric heater is damaged. If the device shows the number "1", then a breakage occurred inside the heating element. The digit "0" indicates a short circuit. In all cases, the defective part will have to be replaced. You can learn how to do this. of this article.
Visual inspection
If you do not have a multimeter, then the performance of the part can be checked with a visual inspection.
First way. Should run the wash. And start watching your electric meter, in particular, behind the wheel. If it is gaining momentum, then most likely the heating element is working.
Second way. Visual inspection. Remove the heating element.To do this, you need to unscrew the nut, which is in the middle. Next, you need to click on the end of the protruding bolt so that it dives, and pry off the heater with a knife. Now that we have the heating element in our hands, we can carefully examine it from all sides. If you find even minor cracks or black specks on the part, then most likely it is defective.
Take note
- When you install a new heating element or return an old one to its place, watch carefully that all the connections are completely sealed. Make sure that the heater gets into the right mount located at the bottom of the tank. Otherwise, the part will touch the drum at the time of washing. Which, of course, is not very good impact on its further performance.
- Do not neglect the preventive measures that will help extend the life of the heater. Every six months, run the wash in standard mode with an empty drum. Instead of washing powder, pour a spoonful or two of citric acid. This method will remove the scum formed in the process. Read more about methods of dealing with scale on heating elements. Read here.
Conclusion
If your washing machine has stopped heating water, do not rush to buy a new one. Perhaps the problem lies only in the faulty heating element. The part should be dismantled and ringing to confirm or exclude the guess that it is damaged TEN washing machine.
If this manipulation did not allow to reveal the malfunction, then a careful inspection of the heating element will help to make sure that it is working properly. If the defect is confirmed, the electric heater must be replaced. New item can be ordered through the service center.
