    Pressure switch not getting activated after motor starts. Normally something blocked in the impellor of the pump. You can split it & check quite easilly. Could be duff pressure sw’ either.

    checked the drain pump and cleared it or is it the circulation pump? or could a slow inlet valve cause this . water coming in but does not sound as loud as other d/w.

    Circulation pump, slow inlet water pressure would also cause exact same problem, as if not enough water has filled when circulation motor starts there won’t be enough water pressure to activate pressure sw’ thus causing machine to go into fault condition.

    💡 check filters in inlet hose

    You can put a meter on the terminals, switches should change over when you blow in to it

    its a high pressure swtich so need a syringe to operate it, unless you have a lot of puff it wont click by blowing.

    I must have good puff, then us Irish are made differently 😀 !

    You could leave pressure sw’ in situ, take off cable connection & meter it when motor starts 💡

    I ordered a new pressure switch (which you could hear click when you blow in it ) and the problem is solved !
    Thanks for your help 😀
