    Hello.
    The dishwasher stopped heating water.
    Checked relay in the control module. He was good but I also mentioned him.
    Tested NTC sensor - functional.
    Proven tacho generator - functional
    Checked heater - functional.

    According to the service, there is still a "(PR) - LEVEL PRESSURE SWITCH" element on the way of supplying the heater. How does he look physically and where to look for him?

    In place of the heater I plugged the meter and it still shows 35VAC.
    In addition, when opening the dishwasher I found one unconnected connector, but I do not see a place to plug it anywhere. It has purple and brown wires and they are of those with a larger cross-section. Is this some additional wiring (richer dishwasher option) or has it really come loose somewhere?

    best regards

    I am asking for the beginning and the end of these wires.

    No, I have disconnected the heater connector and connected the meter. I will put in a picture of the heater when I found it after opening the dishwasher

    Please. Such a view I found after opening the dishwasher. A light blue wire is connected to the heater (the connector is in a plastic cover), and a brown connector without a cover. The cross-section of these wires is smaller than those of "unknown origin" ...

    When I look at it, it really matches the heater. 230V appears on it so I agree. But what other cables do in the heater do not know ...

    Added after 2 [minutes]:

    I didn't buy this dishwasher. She was already in the apartment I bought. Maybe sometime it broke down and someone did some modification? Only why if this cube is 230V, and so far for 3 years of my use also worked properly without this cube ...

    For sure. It looks like a bypass of the hydrostat, but it's best to be seen by an experienced service technician, because this modification can be dangerous.

    Hello.
    I x-rayed the connections in my dishwasher and I have a question.
    For what purpose is the conversion of the dishwasher heater installation used to bypass the hydrostat. The heater is powered by a rectifying diode, and is additionally connected by a relay with a capacitor, resistor and diode. The relay coil is powered by wires coming out of the dishwasher pump?

    I connected the dishwasher according to the correct scheme, i.e. with the participation of a hydrostat and the heater works correctly, so why did you change it?

    I guess you should ask only the author of this modification, the only reasonable explanation would be that the original circuit is not working properly. But if everything is okay, leave it alone.

    I do not know exactly what the pump hoses (white and beige) are from, but it turns out that in such a system the dishwasher heats all the time during the pump operation. I do not know, maybe it was not drying in the original or not perfect.
