A number of codes inform you of problems with heating water, 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 lights signal an error: opposite to the maximum speed (1000 or 800) and after 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!
