Washing machine does not heat water

The washing machine does not heat the waterHeating water to the required temperature is necessary for normal washing of clothes. If the washing machine does not heat the water, then the quality of the wash decreases. For this reason, it is necessary to monitor how hot the water is during the programs.

How can you tell if your washing machine is not heating the water?

Some people check the temperature of the laundry when the wash is finished. And naturally, the laundry will feel cold to the touch. But this does not mean that the machine is faulty. After all, shortly before the end of the washing process, rinsing occurs, which involves cold water. Therefore, this verification method is not correct.

We recommend checking the hatch temperature during the first half hour of machine operation. If during this time the hatch remains cold, then there is a malfunction!

There are times when the wash cycle runs from start to finish, but the water never heats up. In this case, you may notice that the laundry is not washed or smells bad.

Malfunctions

There may be several faults in this situation.

Level sensor faulty

Quite often, in some washing machines, the level sensor tube may become clogged. This happens when washing. Hair, threads or some pieces of fabric may get into it. Such blockages make it difficult for this part of the machine to operate normally. That is, water is poured into the tank. But the heating element does not work. And all because the module is misinformed and does not issue a command for heating.

In order to fix this, you can clean the tube or replace the sensor. You can learn how to make this replacement yourself from the video:

Heating element (heating element) open circuit

Heating element washing machine heating elementAnother possible breakdown is a break in the heating element circuit. In order to check the condition of the circuit, you need to ensure the integrity of the wires that are adjacent to the heating element. In a number of washing machine models, the wires leading to the heating element are located next to the machine body. Such an arrangement may negatively affect their safety. During washing, spinning and other operations, the machine produces vibrations. And the wiring may simply fray. If you discover this malfunction, you must either solder the broken wires or replace them with new ones.

The most common breakdown that causes a lack of heating of water in a washing machine is the failure of the heating element itself. In order to check the serviceability of this part, it is better for us to use a tester. By ringing the heating element we can determine whether it is working or not. If we are convinced that the reason for the incorrect operation of the machine is in the heating element, then it should be replaced with a new one. The replacement process is quite simple. A person without special skills can handle it. To carry out the entire operation, you only need to remove the back cover of the washing machine. Then, loosen the fastenings of the part, remove it and install a new one. You can learn how this is done from the following video:

You must be careful when removing and replacing this part. Since too sharp removal and incorrect installation can damage the plastic tank.

When purchasing a new heating element, you need to be very careful. After all, an unsuitable part may not fit in the place of the old one, interfere with normal operation, or even break your household appliance. In order to find a new heating element, we recommend using the Internet. This is the easiest way to find and order the necessary spare part in your city.

Scale or increased water hardness

Scale on the heating element of a washing machine can occur due to a high concentration of magnesium and calcium salts or rust in tap water. The appearance of scale can affect the heating of water. Since it worsens the functions of the heating element. In order to avoid such troubles, you can use special tools to keep the machine in good condition. For example, colgon. Or install a filter that will soften the water.

Heating sensor failure

Also, one of the reasons why the washing machine may not heat the water is a malfunction of the heating sensor, which is also called a thermostat.

It must inform the control module about the moment when it is necessary to activate the heating device. And if it stops working, then it needs to be changed. To do this, watch the video instructions:

Failure of the programmer or heating element relay

The programmer is part of the control module. It can break for various reasons. For example, contact connections will become charred. The module is a rather expensive and very difficult to repair part. Not every repair service will undertake to restore it. Most often, in this case, the module needs to be replaced.

We do not recommend replacing the control module yourself. If you do not have the appropriate skills, then it is better to turn to specialists.

    Thank you, everything is very clearly described! Great help!

  2. Gravatar Larissa Larisa:

    Thanks for the advice, now I know that the machine washes with cold water and the water is heated in the machine.

    • Gravatar Tatyana Tatiana:

      The machine washes with hot water. But it’s picking up from a cold pipe

  3. Gravatar Konstantin Konstantin:

    Question. And what is the most likely reason for the non-heating, if the water does not heat up only on the program with 40 degrees Celsius, i.e. If you set it to 50 or 60 degrees, then heating occurs.

  4. Gravatar Glory Glory:

    So I have a question, heating occurs only when washing at 40 degrees. If you set the wash to 60-95, water just immediately pours into the machine.
    What's wrong with this? Thank you.

    • Gravatar Vladimir Vladimir:

      The water level sensor is faulty.

      • Gravatar Pavel Paul:

        Yes! For one thing, the sewer may be clogged. Well, “masters”...

  5. Gravatar Natalia Natalia:

    Question. What could be the reason if the water does not heat up even at 30%?

  6. Gravatar Boris Boris:

    I put the heating element in the car, water flows from under it. Maybe the gum has dried out?

  7. Gravatar Anonymous Anonymous:

    Hello. Please tell me, my eyes are blinking, where is the key? What should I do?

  8. Gravatar Kiril Kiril:

    The machine heats water normally at 95 degrees, but does not heat at 60 degrees, is the problem in the thermostat?

    • Gravatar Ahh Ahh:

      I also have the same problem: at 90 degrees it heats normally, but at 60 it doesn’t heat. What is the problem?

  9. Gravatar Alexey Alexei:

    The Indesit washing machine does not heat the water. The heating element and temperature sensor are working, but the water does not heat up. What other reasons could there be?

  10. Gravatar Yura Yura:

    Hello, have you found the reason? I have the same problem.

  11. Gravatar Denis Denis:

    Most likely the power relay on the board has failed.

  12. Gravatar Valery Valery:

    Thank you. Intelligible.

  13. Gravatar Natalia Natalia:

    At a temperature of 40° the machine washes normally, when you set it to 60° it gives an error.
