[Gesser]

Hello friends.
Please tell me about this dishwasher.
After starting the washing program, the pump starts pumping water and does not stop. Water begins to flow out from under the door, everything flows into the pan. In principle, there is no emergency flood sensor in the pan. The float with two limit switches appears to be normal, the limit switches work. True, one is connected as normally closed, the other as normally open. Maybe there is something wrong with them, because before this some hands have already climbed into this dishwasher.
The second assumption is about the pressure switch, as I understand it, it is located on the tank with resin. The question is - can it get clogged?
Please do not kick too hard when just starting to understand the structure and repair of dishwashers. If necessary, I can provide all photos from all sides.

They say this happens because the sensor that is responsible for the water level is filled with fat. Fat sticks to it and it remains in the position that there is no water yet. and pours endless amounts of water. To get rid of the problem, we need to disassemble or wash the grease trap so that the sensor can move freely and nothing interferes with it
