    Hi,

    I’ve trawled the forum but could not find the answer. Perhaps someone can help…

    I have a Bosch Logixx 7 dishwasher that has developed a fault that when switched on, two warning LEDs flash in unison – the one beside the tap icon and the one beside the rinse aid icon. The machine will no longer enter any cycles due to this error at startup. There is no accompanying ‘E’ error, just the two flashing LEDs.

    This has been happening during wash cycles for a while at completely random points during the cycle but could be cleared after a few on/off switches. It’s now permanent even after having been disconnected from the mains for a period.

    Do you know what has failed? I’ve tried the forum but there is no info on this particular fault scenario.

    Here are the code numbers from the machine in case they help :-

    SMV69T10GB/27
    AKO 732941-10 Typ:TV
    35 100 906
    BSH 900 385 466 01825

    Thanks!
    Mr.M

    Use this format with the lights and someone may know, I don’t have codes for that model…

    XOOXO

    Where X is lit, O is not.

    What they have as a graphic is often irrelevant as it varies from model to model as the functionality of the LED or button can vary even using the same control board.

    I called an engineer out as not clear which part has failed and I didn’t want to risk ordering something and it not fixing the problem.

    He’s not seen this fault before and it wasn’t listed within his technical pack. The Bosch bods I spoke with first didn’t know what it meant either. One ventured that it might be caused by a leak in the region of the rinse aid dispenser, but does not look to be the case.

    Engineer suspects it has to be the main PCB board underneath (accessible from the right hand side). He’s coming back with a price for that – I’m tied in now as have paid £60 call out.

    Hi Mr M,

    I have the very same problem you had.

    This is the only place I have found any reference to it.

    Please could you let me know if the replacement of the PCB was the fault. My PCB is the same as your AKO 732941.

    Many thanks

    Hi Mr M,

    I now realise that there are two PCB’s one in the door and the other underneath the dishwasher on the right hand side.

    Please could you let me know which PCB you had to replace to solve the problem.

    Many thanks

    Hi to any body out there with this problem.

    It was the main control board – fitted to the bottom right of the machine. One of the chips had overheated and split!

    All working now!

    Cheers
