    Hi Guys

    Got a neff dishwasher overfilling, Do loads of these and normally without any real problems anyway this one is causing grief.

    Float side chamber and hose to sump clear and even replaced the pressure chamber complete with microswitches bsh263186.

    Starts to fill, circ motor kicks in runs ok, then fills more switches then stops filling, a few seconds later fills again this time dose not stop nor does it operate the overfill protection, leaks out of door seals?

    once it reached it level is it then controlled by pcb for time out?

    Have checked for shorts etc, running out of ideas.

    Anyone??

    Cheers

    I’m thinking it’s likely a PCB problem. 🙁

    The PCB calculates the time taken between the initial fill valve activation and the moment the level (full) switches operates, then the PCB adds another 200 ml on top of that. So I figure that that is the point where the PCB should shut off supply to the valve but doesn’t?

    I’ve never come across the problem myself therefore not 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} on that, so maybe the BSH boys can help me out here? 😕

    Thanks Martin

    That was my initial thought, but you dont want to believe it at first!

    Oh well i will wait and see if anyone else can just confirm this as well then quote the customer :rolls:
