    Got this one today and thought I’d throw it to my learned friends before
    sticking a timer in.
    Select a wash programme 4 and it goes into the preselect
    Passes through dry……
    then again………
    😕 and again……. 😯
    then comes to rest with the led’s showing rinse. But what you hear is the pump, water filling and the drum in distribute. All at the same time.
    D’yer reckon it could be a timer fault.

    Thats a nice fault.
    I would firstly check for earth leakage.
    Failing that possibly a power module fault.
    Boro might be able to shed more light on it 😉

    Agree with Greg, that is a lovely fault.

    Definately give it a blst with megger aswell. Fault display on this model is displayed via the wash led’s (yellow) being on constant and the dry led’s (red) flashing.

    If I recall the selector s/w 058797 was prone to failure after time, but going by your description does sound like power module problem expensive at £153.
