    Hi I have a Siemens SN66T097GB/74 which is flashing the tap and rinse aid lights, the PCB has no signs of damage so I have tried replacing it but it’s still doing the same thing.
    Can anyone give me some advice?
    Thanks, Darren

    as far as i know a flashing light tap symbol is just an indication there is a fault but never worked out how to tell which

    do any other lights change and stay lit when it faults out

    does it fault out immediately or wait 5 mins or so ?

    Thanks for getting back to me, it flashes along with the rinse aid light as soon as you turn the on off switch on.
    I have had these lights flash before and replaced the PCB to fix it but not this time

    bit of a long shot as siemans manuals are rare

    https://www.manualslib.com/manual/958098/Bosch-She4am12u.html?page=8#manual

    closest i can get
    try to see if their ways of extracting fault codes works on your unit

    The Tap symbol is the appliance way of saying fault encountered but no way of fi ding out what without running through a quick wash and seeing where it fails. 90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the time I find the heat pump to be the cause. This can be tested with the module removed just enough room to get test probes in and check for continuity.

    only if the light is not flashing as thats the fill error signal. if its flashing it could almost be anything else
