Polar PFL 1000 Washing Machine - Overflow, Flooding, Pumping Issues, and Black Coating on Elements

When I arrived home for the holidays, I learned that my parents have a strange problem with the title washing machine. It seems that several times it overflowed with water and flooded the bathroom. The water spilled out through the powder drawer. I turned on the rinse + spin program and see that it hangs on pumping water and "pumped" all the time. Sometimes he does not pour water at all. The pump probably works, because when I put a water hose into the powder drawer, it normally pumps out.

I turned on the driver, a few LEDs, resistors and coils were covered with a black coating, I thought that something burned, but it looks like these elements are ok. I improved February under larger elements. She did well one wash and again the same In the picture below I marked elements that were black (photo taken from another thread in this forum).



I just noticed that after disconnecting from the electricity for a few minutes it probably starts to work normally. Could the microprocessor or firmware go out?

You have a blocked hydrostatic system (this can with a hose and cables on the right in the programmer area). The tube is led from the prestige to the above hydrostat, the prestige is located at the bottom of the tank, it is (prestat) probably jammed. To get to the prestige you have to disassemble the front part of the washing machine with the sight glass. The module is in working order, these paths are dirty due to the static field on the inverter.

I was also wondering if there was anything to do with the water sensor, but I could not locate it. Thanks for the info, I will try to clean it
