Error code F20 in the Bosch washing machine

A number of codes inform you of problems with water heating, and F20 is also one of them. If it appeared on the display of the washing machine, it means that there was a malfunction in the heating element or something indicates this malfunction. In this case, the water temperature is higher or lower than indicated in the washing program. If your model does not have a display, then two bulbs signal an error: opposite the maximum speed (1000 or 800) and through one from it (800 or 600):

In addition, the washing program will stop before the scheduled end. Perhaps, in this case, the buttons on the panel will stop responding to pressing. Please note that the problem is critical and may cause a short circuit in the mains. Be careful!
