Bosch SMV 50E10 RU please help me diagnose
It started with the activation of the aquastop, the machine (hereinafter referred to as PMM) hummed, did not turn off, and was pulled out of the socket. Then it was plugged back into the outlet. For some time the network turned on spontaneously, but a day passed. It worked fine for three days, but then it stopped heating the water, although the cycle was complete. Then he began to knock out the introductory machine (RCD). The inspection did not show any crime; no flooding was found. A repairman was called, the machine stood idle. Upon the arrival of the specialist, the PMM was connected to the network, and, lo and behold, the machine started working again like factory. The water is heating, everything is on schedule. The miracle lasted for three days, after which the PMM stopped heating the water again, and after several washes (with cold water) the machine began to break out again. Upon opening, a fairly burnt and, accordingly, non-functional aquastop switch was discovered (the resistance was over three hundred ohms). The switch was restored, the PMM worked normally again. Three days. After washing at 70 degrees, the water stopped heating again. There was moisture on the bottom, but not on a global scale. I wiped the pan and began to drive the PMM in search of leaks. I spent a day, no leaks, no water heating either. The aquastop sensor, that is, the switch, was not in its normal place, hung separately on the wires, and did not affect the process in the event of a leak, and was obviously already in good working order. However, pressing the button on it stopped the washing, but the drain pump did not start. But if you pull it out at all during washing, then the standard emergency procedure starts - the drain pump turns on, regardless of the position of the door and the pressing of the buttons. The next day, the PMM was already working as expected - it heated the water, pressing the aquastop button turned on the standard emergency mode. The heating element rings 21 ohms, thermistor 2*9 kOhm. No comments were found on the tracks, no ground calls. No clearly visible leak was found under the magnifying glass. I took everything apart, even the door. And yet, water is not poured into the container where the salt is poured. The resistance of the retractor coil is 2.4 kOhm. There was an idea that there was a leak in the pump, moisture got onto the tracks near the connector and from the power circuits stray voltage through the water was supplied to the contacts of the thermistor, which blew the mind of the control unit, but is this possible? Again, no traces were found. Well, where else to dig?
