The washing machine does not heat water.
Heating water to the required temperature is essential for proper washing. If the washing machine doesn't heat the water, the washing quality will be compromised. For this reason, it's important to monitor the water temperature during the cycle.
How do you know if your washing machine isn't heating the water?
Some people check the temperature of the laundry after the wash cycle is complete. Naturally, the laundry will feel cold to the touch. But this doesn't necessarily mean the machine is faulty. After all, shortly before the end of the wash cycle, a rinse cycle occurs, which uses cold water. Therefore, this testing method is not reliable.
We recommend checking the sunroof temperature within the first half hour of operation. If the sunroof remains cold during this time, there's a problem!
Sometimes a wash cycle runs from start to finish, but the water never gets hot. In this case, you may notice that your laundry isn't clean or smells bad.
Malfunctions
There may be several faults in this situation.
The level sensor is faulty
Quite often, the water level sensor tube in some washing machines can become clogged. This happens during the wash cycle. Hair, thread, or other fabric particles can get caught in it. Such blockages hinder the normal operation of this part of the machine. This means that water fills the drum, but the heating element doesn't engage. This is because the module is misinformed and doesn't send the heating signal.
To fix this, you can clean the tube or replace the sensor. You can learn how to do this yourself in this video:
Heating element (TEN) circuit break
Another possible problem is a broken heating element circuit. To check the circuit, ensure the integrity of the wires connected to the heating element. In some washing machine models, the wires leading to the heating element are located near the machine body. This location can negatively impact their integrity. The machine vibrates during washing, spinning, and other operations. This can also cause the wiring to fray. If you discover this problem, you will need to either solder the broken wires or replace them with new ones.
The most common failure that causes a washing machine to not heat water is a failure of the heating element itself. To check the functionality of this part, it's best to use a tester. By ringing the heating element, we can determine whether it's working properly. If we've confirmed that the heating element is the cause of the machine's malfunction, it should be replaced with a new one. The replacement process is quite simple and can be performed by anyone without any special skills. To complete the entire operation, you only need to remove the back cover of the washing machine. Then, loosen the fasteners, remove the element, and install the new one. You can learn how to do this in the following video:
Care must be taken when removing and replacing this part. Excessive force and incorrect installation can damage the plastic tank.
When purchasing a new heating element, you need to be extremely careful. An incorrect part may not fit the old one, interfere with normal operation, or even damage your appliance. To find a new heating element, we recommend searching online. This is the easiest way to find and order the necessary part in your city.
Scale or increased water hardness
Scale buildup on a washing machine's heating element can be caused by high concentrations of magnesium and calcium salts or rust in tap water. Scale buildup can affect water heating, as it impairs the heating element's performance. To avoid such problems, you can use specialized maintenance products, such as Colgon, to maintain your machine. Alternatively, you can install a water softener filter.
Heating sensor failure
Another reason why a washing machine may not heat water is a faulty heating sensor, also known as a thermostat.
It should inform the control module when the heating element needs to be activated. If it stops working, it needs to be replaced. For instructions, watch the video:
Failure of the programmer or heating element relay
The programmer is part of the control module. It can fail for various reasons. For example, the contact connections may become charred. The module is a fairly expensive and difficult-to-repair component. Not every repair service will undertake its repair. Most often, in this case, the module must be replaced.
We do not recommend replacing the control module yourself. If you don't have the necessary skills, it's best to contact a professional.

Thank you, everything was explained very clearly! You were a great help!
Thank you for the advice, now I know that the machine washes with cold water and the water is heated in the machine.
The machine washes with hot water, but it fills with cold water.
Question: What's the most likely reason for the water not heating up if the water isn't heating up on the 40 degrees Celsius program alone? If I set it to 50 or 60 degrees, it does heat up.
I have a question: the heating only occurs when washing at 40 degrees. If I set the wash to 60-95 degrees, the water just fills right into the machine.
What's wrong here? Thank you.
The water level sensor is faulty.
Yes! The drain might have clogged up too. What "masters"...
Question: What could be the reason if the water doesn't heat up even at 30%?
I'm installing a heating element in my car, and water is leaking from underneath it. Maybe the rubber seal has dried out?
Hello. Please tell me, my light is blinking, where is the key. What should I do?
The machine heats water to 95 degrees normally, but it doesn’t heat it to 60. Is the problem with the thermostat?
I have the same problem: at 90 degrees it heats up fine, but at 60 it doesn't. What's the problem?
My Indesit washing machine isn't heating the water. The heating element and temperature sensor are working properly, but the water isn't heating. What other possible causes could this be?
Hello, have you found the cause? I have the same problem.
Most likely the power relay on the board has failed.
Thank you. Clearly explained.
At a temperature of 40° the machine washes normally, but when you set it to 60° it gives an error.
