Why did the water heating suddenly stop working during washing? This is one of the most common problems with modern washing machines. Service workers responsible for the repair of household appliances can easily determine the causes of the breakdown and be able to eliminate them. Commoners go into a stupor when the washing machine does not heat the water. This damage is very serious, because washing in cold water is not effective. In this article, we will explain
Checking water heating
If the washing machine does not heat up the water, then the device may display an error during operation, and then interrupt the wash immediately. Older models do not have this feature. In order to find out if the water heating is working, it is recommended to start the hot wash mode. After half an hour, if the lid is warm, the water heats up normally, but when the glass remains cold, it means that the water is not heating, therefore, the machine is broken. For a washing machine with horizontal loading, it will be problematic to check the water heating in this way.
To troubleshoot the problem, identify the root cause. It is worth highlighting here:
- clogging of the water level sensor (pressure switch);
- problems with the wiring of the tubular electric heater circuit;
- scale formation on the heating element;
- Heating element burned out;
- malfunctions of the thermostat;
- breakdown of the control module.
If you consider each of the reasons in more detail, you can understand what to do in order to eliminate this or that breakdown on your own.

Clogged water level sensor
Absolutely all modern washing machines have a special sensor that is responsible for the water level in the machine, closing the circuit and starting work. The ingress of various debris can cause the sensor to stop leaking water. In any case, if you are faced with a similar problem, you just need to clean the sensor tube. If the washing machine still does not heat the water, then you can replace sensor on new.
Open circuit heating element
Another reason why the washing machine does not heat the water is a break in the wires going to the heating element. If at least one wire breaks when disassembling the machine, the tubular electric heater (TEN) will not perform its functions. In most cases, the element's circuit wiring is located inside the washing machine, next to the case. Spinning and drying involves the vibration of the washing machine, which can lead to grinding and wire breakage. In this case, it is recommended to solder them. If the heating element still does not work, it is necessary to replace the entire damaged wire.
A breakdown of the heating element should not be ruled out. To check the heating element, it is recommended to ring it with a multimeter. If the cause of the breakdown lies in the heater, then it is recommended replace the heating element of the washing machine... To do this, you need to remove the cover of the machine body, loosen the heating element fasteners, and replace it with a new working part. It is worth remembering that improper removal or installation of the heating element can damage the washing machine tank.
When purchasing a new heating element, you should pay attention to its shape. An unsuitable element may not fit into the place of an old part or cause damage. The new tubular electric heater should be selected specifically for the specific model of the washing machine.
Scale formation on the heating element
If after rang and checked the heating element, it will turn out to be in good order, you need to make sure that no scale has formed on it, which prevents the water from heating. If such a problem was found, it must be eliminated by boiling the heating element with citric acid until the scale dissolves completely. For prevention, it is recommended to use special chemicals or powders, for example Calgonum for washing machines... It is also recommended to periodically run boiling water with citric acid through the washing machine. In addition, installing a water filter will help get rid of scale.
Water heating sensor breakage
The thermostat responsible for heating gives a signal to turn heating on or off. If this sensor is faulty, the water may not heat up, or, on the contrary, it may heat up to the maximum temperature. In any case, in the event of malfunctions, a thorough check is recommended. If necessary, the sensor should be replaced.
Control node malfunctions
Every modern washing machine has a control module. Unit breakdowns will certainly affect the operation of the entire washing machine. Breakage and oxidation of contacts, as well as ingress of moisture or condensate inside the module will lead to its breakdown. Control unit repair - a laborious and very costly business, therefore, service center specialists recommend making a complete replacement. There is an option to exchange the old board for a modern, reliable and durable one.
