[Solved] Bosch SMV50E70EU dishwasher - tap lights up before the end of the program

Hey,
I have a problem with the Bosch SMV50E70EU dishwasher yesterday.
symptoms: the dishwasher is normally washed, almost the entire program is made. Most likely, during the rinsing, it stops, the tap is on and squeals as at the end of the program. The dishes are clean but not completely rinsed. Unfortunately, the dishwasher does not have any display, so I do not have any error code.

I checked all filters, hoses, pump to pump out. Everything looks good, it's clean. In the evening I will continue to check individual elements. I'll let you know if I found anything. I will be grateful for any suggestions on where to look.

1. A sieve at the entrance of clean water.
2. The whole drain carefully.
3. Tray under the dishwasher tub.
4. Hydrostatic system.

Yesterday I had a moment to deal with the diagnosis.
I've probably got to the accumulation, because I found two failures: a piece of cloth wound on the pump axis of the pump and the broken heater.
Everything can be seen in the pictures.
The film turned out to be very helpful when extracting the heat pump. It shows how to pull out the heat pump without dismantling the entire dishwasher.



The new pump-heater costs 118? But before I order a new one I will try to fix the burned path. Let me know if I succeeded.













I am sorry for the lack of Polish characters, but I only have a German keyboard at my disposal.

The path on the heater was soldered. The dishwasher works as it should. I only have doubts about the durability of this solder. Getting contact was very difficult. If the heater drops again, it will write the appropriate note here.
edit:
The path on the heater has been repaired and the heater is working properly.
