Causes of Heating Problems
If you suspect that your Bosch washing machine is not heating the water, you need to make sure of this.
If the Bosch washing machine continues to operate until the end of the program without displaying an error message, you need to make sure that there really is no heating.
You can do it this way:
Select a program with water heating.- Start the work cycle.
- After 10-15 minutes from the start, touch the glass of the hatch with your hand.
- If the glass is warm, then the heating is fine.
- If the glass is cold, you need to double-check that the settings are correct.
Some programs do not require heating or wash clothes at a minimum temperature of 30? C, which practically does not feel like heating.
In the case when heating does not really start, you need to move on to analyzing the condition of the Bosch washing machine.There is a possibility that heating does not start due to the fact that the washing machine is constantly filling and draining water.
This can happen if the Bosch machine is installed incorrectly, when the drain hose simply lies on the floor and does not have the necessary rise above the level of the tank. The solution to the problem is to install the equipment in accordance with the manufacturer’s recommendations.
Diagnostics of a Bosch washing machine, troubleshooting methods
Lack of heating when choosing the correct Bosch program and settings always indicates a breakdown. To clarify the condition of the components, the washing machine will need to be partially disassembled. But first you need to disconnect the device from communications: be sure to unplug the plug from the socket and close the tap that supplies water to the washing machine.
The heating element burned out
Failure of the heating element is the most common error according to statistics, which leads to problems with water heating. The tubular electric heating element is located under the drum of the Bosch washing machine. The unit is accessible with the front panel removed.
To analyze the condition of the part, a multimeter is used and a visual inspection is carried out. The part that has become unusable is replaced with a new one. Details - in this article.

Thermostat failure
If the temperature sensor fails, the Bosch washing machine cannot determine whether heating has occurred or not. The temperature sensor is located on the heating element. The functionality of the element is checked with a multimeter. Broken part needs to be replaced.
Failures in the control module
The control unit controls the operation of the Bosch washing machine and coordinates the switching on of the units.
If certain elements on the board burn out, signals related to water heating are not received or received. As a result, no heating occurs.
Solving the problem - repairing the module. It is accessible with the top cover and top control panel removed.
Repairing the control module is a complex task that requires knowledge in electronics and special equipment, so it is better to entrust it to a specialist.
Wiring violations
In a Bosch washing machine, the main components are connected by electrical wires, through which signals pass from and to the control unit. If contacts are broken, wires or the entire loop are broken, information stops passing through. Such a breakdown can lead to a lack of water heating, as well as other failures.
Water level sensor
If the water in the Bosch machine does not heat up, then One of the possible reasons may be a breakdown of the water level sensor. This element of the washing machine is not directly connected with heating, but if it fails, the water may not heat up.

Possible difficulties
If there is no water heating, and searching for a solution to the problem, you may encounter certain difficulties:
| Problem | Ways to solve the problem |
| The washing machine is under warranty | You should not open the washing machine body yourself. If a failure is detected, you need to contact the service center |
| The new heating element does not fit into the seat | Most likely, a heating element that was not suitable for this washing machine model was selected. |
| Can't get the heating element | The part is held in place by a central nut. In addition, the heating element itself “sits” quite tightly, which allows you to avoid leaks |
| After replacing the heating element, the water in the drum still does not heat up | It is necessary to check the other components that are involved in the water heating process. There is a possibility that it was not only the heating element that was worn out |
