    This machine washes fine but the pump keeps running even though its emptied all the water….. even if its turned off at the plug then back on after a few minutes it still has the pump noise going – it does eventually go off and the machine will work fine until the end then the problem comes back

    Is this a pcb issue because the base is clear of water or something I’m missing?

    this is an old one

    check left hand side for deposit build up
    if ok probably a bad triac on the board. A lot of times when the triacs fail they will half wave so check pump voltage. if its about half voltage then almost certainly triac. Beware if programmer fires triac it will probably be normal voltage so you need to attach meter and watch
