    Hi Dave, thanks for the response. There doesn’t seem to be any sequence. It continually flashes and beeps also, until I turn it off. :rolls: :rolls:

    Re: Whirlpool Dishwasher

    in that case it could be fault 1

    ntc (thermostat) fault.

    it could be
    1 the NTC
    2 broken wire from the timer to the NTC
    3 faulty timer

    Hi Dave, is the ntc thermostat east to get at ? :rolls: Is there an exploded parts diagram anywhere. Appreciate your help.

    Re: Whirlpool Dishwasher

    the ntc is a small probe that plugs in the bottom of the sump so it in the water. take the filter out you should see it sticking up prob front right of the sump

    google 481228268012

    this may not be the correct part number for yours as there are a number of models with the same model. but it will give you a picture.

    check the wiring first

    Re: Whirlpool Dishwasher

    HI Dave, thanks. Presumably it connects to the main control board in the door? I did have a problem last year with the plastic cover over the board wires failing and the sharp metal of the door cutting a wire and shorting the main pcb. I thought I had covered and protected the wires aginst that happening again. I’ll let you know how I get on. And thanks again for your help with this. 😛

    Hi Dave, not the sensor or wiring. Wiring checked between circuit pcb plug and plug for the sensor – good continuity both wires. Also compared sensor with another and resistance the same- but changed it anyway. Fault still the same. You mentioned the timer in your list. Where is that ? Is it on the main PCB in the door ? Also,noticed there is another gismo with a wired connection in the sump. Could this be the problem ? :eeek: :eeek:

    Re: Whirlpool Dishwasher

    the timer is the pcb board itself so may be that not reading sensor properly

    Dave

    obviously I cannot promise changing the board will cure it

    Re: Whirlpool Dishwasher

    Hi Dave ? I’ll give it a quick once over to see if there is anything obvious on the PCB but I have already replaced one ( mentioned earlier) so it might be a new dishwasher. 😕 😕 😕
