    Hotpoint dishwasher shows f12 fault on display panel. Model fdfsm 31111

    It’s only just over a year old. It does seem to have water down by the filter. Otherwise it looks like it could be Communication problem between the main panel and the motherboard. Any suggestions to put this problem right

    I have an FDM550, it has completed a wash and I have emptied the washer, but now the wash light flashes continuously. I have tried switching it off at the mains and leaving for 30 mins. As soon as I power it on again, the light starts flashing. It sounds like it’s trying to empty the water out, but it has already finished the cycle.

    Hi Paul
    I have hotpoint Aquarius FDM550 dishwasher
    When I turn it on no water fills and I have the rinse aid, salt, wash and end lights flashing?!
    Can’t seem to find that error code on manual troubleshooting page. I have pulled out the filter and it’s clean!
    Please help! Hopefully something silly as I can’t afford a new one with Christmas next week!

    Dishwasher FDYB 11011P giving an A10 fault. Salt and rinse aid and start lights flshing after about 10 mmiutes. As per your youtube video we removed the pump motor.

    Across the element it reads 13.8 ohms. Between terminal on side marked red and the heater element terminal it is open circuit. Is this correct? Is the terminal block switchedor faulty.

    If we need a new pump what would be the cost.

    Listing A01, A02 – – A10 etc., is OK but you need to list which light combination correlates to each fault code.
