Bosh 33A13/14 does not heat water, the cycle does not complete
The resistance of the heating element corresponds to the power (it has not applied direct voltage yet), the temperature sensor changes resistance when heated from 50 to 15 kOhm.
In the case with A water presence sensor is embedded with a heating element; water presses through a rubber membrane on the piston, and it presses on the microscope. There are doubts that it shorts, but I simply bypassed it.
They write that there must be a pressure switch somewhere - I can’t find any pressure switch.
I measured the voltage on the heating element during the washing process - about 120 volts. What could it be?

I’ll add - the first thing I did when it broke was to clean all the filters, + fill in various detergents and turn it on. Ten without plaque.

I didn’t think of measuring the voltage not on the heating element, but on the contacts, disconnecting them from the heating element. It’s still standing disassembled. Looks like the control unit is the cause.

The soldering of the heating element electromagnetic relay has fallen off on the control board. That is, I just melted away from long work. The relay itself is intact, just soldered. But during disassembly and reassembly, one of the connectors crumbled; it will have to be replaced or some kind of collective farm attached.
