    Hi all

    Select prog, press start- door locks & machine starts process, after 15/30 secs it shutsdown & display goes blank.
    Power to machine & board OK.
    took pcb apart & checked caps & joints – all appear ok.
    Would have thought it must be Power or operating module, 😕 But which one?
    Any clues anyone

    Clive.

    its one of those questions and there is no clear answer but it does sound a bit like a power problem
    chances are the power board uses a switch mode power supply. the chips they use sometimes fail so my next step would be to arrange to check the output voltage of the chip after the machine fails. I expect an output voltage of say 12 to 20 volts if it starts ok then goes to zero you have found it
    also had a miele with a similar problem ended up being a voltage regulator chip failing after start up

    Thanks Dave,
    Don’t suppose you have a wiring diagram then ?
