    not been used for a couple of days dial, at 12 o clock in the off position.
    machine then decides to turn itself on with door light flashing.and dial still untouched at the 12 o clock off position.
    obviosly theres a ghost in the house.??
    back to seriousness,unpluged the machine to see if it would reset,this didnt work .so would i be right in assuming this is a board problem.
    cheers ,darren

    How many times did you tried and fail?

    ddirect, try that just with little alcohol…
    and advice customer to unplug machine when she isn’t use it because is more safty and machine will live much more (because any fluctuation from power supply network will shorting PCB life). And explanation for this malfuction is that: all time between middle potentiometer pin (cursor) and both other two pin’s exist diferential potential which will form like magnet field (because of thin distance) and attract dust which on his turn will conduct current… result output from stanby mode…

    Colleagues, I have a question: how many of you did try that and didn’t worked?

    Mates,
    I have to apologies for my earlier replies… :haier:
    Yesterday I’ve received ten PCB’s with same problem: do not reset or even do not select another program…
    I’ve done my work like earlier job: cleaned potentiometer and change it with temperature one but further I wanted to see which are my work results…so I took my laptop and using one of merloni programs for EVOII 💡 I have check and see how PCB is seeing potentiometers (if you turn potentiometer one step you should see it into display also):
    – program selector looks OK (former temperature potentiometer), :tright:
    – temperature selector is not registering same values in supposed position on all ten repaired cases. :tdown:

    So, cleaning them isn’t a solution…you have to replace them with new ones…
