    Hello.
    I have a problem with the dishwasher as in the subject.
    The day before yesterday the dishes were greasy after washing, so it fell on the heater - unfortunately not.
    The dishwasher has 4 programs with water heating. On 2 of them (auto 55-60 and 50 degrees) it does not heat at all. The voltage comes to the switch on the heater, but the plug activating the switch comes out, but not when there is a need (several times and all that) cold water throughout the cycle.
    On the 45-degree program, the washing itself takes place normally - the heater heats, washing in warm water, only at the end the dishes are cold - and in the end should be heating the dishes to dry faster - but the heater no longer heats at the end.

    1. Heater efficient - resistance 26 Ohm - efficient microswitch.
    2. Hydrostat + water jacket cleaned - all microswitches working on it.
    3. The efficient + clean solenoid valves - tested in the service menu - one was suspended before cleaning.
    3. The control panel board is visually perfect.
    4. During the heater test in the service menu, something (some signs) flashes on the display so fast that it can not be read.
    5. Filters cleared. There were several lemon seeds in the bowl (I wonder how they got past the filter)
    6. Arms are moving decently.
    I wanted to reset her factory settings - reset, but I did not find any information on how to do it.
    I will be grateful for your help.

    Added after 36 [minutes]:

    I noticed now that when the mushroom on the heater controls the switch, unfortunately there is no tension on the heater. However, when the switch is not controlled, the voltage on the switch is.
    I have no idea what to do next ...

    It is a pity that no one has an idea for my case.
    New informations.
    I built the control board, measured the relays.
    I connected 5.25V to each of them (without desoldering), one did not hold (only chirping).
    After this measurement, unfortunately, the dishwasher draws in and out the water.
    I exchanged two, the one who ticked and the heater, but nothing changed.
    The water is taken and pumped out.
    As soon as it enters the test mode of subassemblies, at mode 02 all the lights come on and go out, and the machine turns off, and when switching to another test quickly, on 05 it is always on / off.
    Please help :)

    You killed ...
    Certainly not to death ...
    Only the need for a "specialist" ...
    Maybe somebody will be found ...
