Equipment of this type consists of many components, systems, and parts. That is why there are several explanations why the washing machine does not heat water:
– damaged heating element;
– the thermostat does not work;
– failure in the functioning of the software device or electronic module;
– breakdown of the water level sensor;
– errors in connection to the drain system – “siphon effect” (liquid immediately flows into the sewer);
– scale on the heating device.
To find out for what reason the unit does not heat water, it is necessary to learn in detail about each fault.
Damage to the heating element
One of the frequent breakdowns due to which the machine does not heat water is problems with the heating element. The average service life of this element with proper operation is 5 years. After that, it becomes prone to heat transfer and overheating. If the heating element in the washing machine does not heat due to its burnout, then this element cannot be restored. It must be replaced with a new one.
Only a master can determine the malfunction of the heating element. This requires not only certain knowledge but also a special device – a multimeter (tester). In addition, for the accuracy of the test, you must use a certain formula: R (resistance) = U² (mains voltage) / P (heater power).
Based on this, the diagnosis and replacement of the heating element should be entrusted to a specialist with experience, otherwise, there is a risk of only exacerbating the problem, as a result of which the machine will need expensive repairs.
Faulty temperature sensor, which is why the washing machine does not heat the water
The tank of any machine is equipped with a thermostat. The sensor is located on the surface of the heating device. It is a small cylinder with electrical wires. The thermostat is responsible for heating the water to the required temperature.
There are 3 types of temperature sensors in total. Each of them is arranged in a certain way, so it is not recommended to repair this element yourself
Important! If the thermostat is not replaced in time, it will lead to the burning of the heating device.
Failure in the functioning of the electronic module or programmer
The programmer itself consists of several elements at once: synchronous motor, contacts, cams responsible for the operation of the synchronous motor, and gear reducer. All of them can break, which will cause a malfunction of this device. This will negatively affect the heating. In addition, for this reason, water may not be collected at all.
It is worth noting that there are many factors due to which the control module can fail. The most common is a violation of operating conditions. Most often, it will be enough to make repairs to eliminate the breakdown. However, in special cases, it may be necessary to replace the electronic module.
Failure of the water level sensor, as a result of which the washing machine does not heat the water
Most modern washing machines are prone to such a breakdown. If the sensor does not work during the operation of the equipment, the unit will not be able to carry out normal washing. The device itself is a plastic part to which electrical wires are connected. To remove the sensor, you need to disconnect them. If you do the repair yourself, then when connecting the wires, you can make a mistake that will lead to negative consequences, which entails unplanned expenses.
Not only cold water indicates a malfunction of the water level sensor, but also the lack of spin. Because of this, the quality of washing greatly deteriorates.
Errors in connection to the drainage system
In this case, it means an arbitrary flow of water into the sewer or its return from the drainage system to the tank. This is due to improper connection of the equipment. If you install the unit yourself, it is important to carefully read the instructions before doing so.
Important! The drain hose must be raised to a height of at least 60 cm. If you fix it lower, then there will be a self-drain. That is, the washing water will immediately flow into the sewer.
If the unit itself is not properly installed, then during the washing process it can vibrate, shake and make a hum. Connecting the machine is a responsible process, on which the service life and quality of washing things depend.
Scale on the heating element
The appearance of solid deposits on the surface of the heating element is caused by violation of the operating conditions of the equipment, hard water, and low-quality household chemicals. This is one of the main reasons why washing equipment does not heat water. If you do not clean the heating element, it will lead to a number of other breakdowns. For example, scale particles can clog the drain hose, damage the nozzles or the tank wall and become a source of unpleasant odor. To clean the heating element from the scale, it must be removed from the machine.
Important! Many users use special products that prevent the formation of scale, which immediately eliminates this fault. This is the most common mistake. Even when using special means, solid deposits form on the surface of the heating element, although it happens much more slowly.
Now you know what to do if the washing machine does not heat water. The main thing is to correctly identify the cause of the malfunction. If you doubt the correctness of your definition, then contact the master. He will diagnose and accurately identify the fault, and then correctly eliminate it.
