    Hi
    I have a Whirlpool ADG 7440 (8542 440 15810) about 7-8 years old which has started to do the following
    On any selected cycle

    1: runs the drain pump for 30-60 seconds, then pump stops (any water in sump is pumped out)
    2: starts to beep continuously

    On opening the door the rinse cycle light is on
    The warning light is flashing continuously

    I previously had what appeared to be a problem with pump out
    but this disappeared after letting the machine sit for a couple of weeks

    Also it is possible that the power cut off to the machine during a cycle

    I have seen similar issues on this forum but for different model numbers, apologies if I am repeating

    What is the cause ? And how do I fix it ?
    How do I gain access for any part replacement that might be required ?

    Thanks in advance

    Peter

    Continuous flashing is the temperature sensor failure. This is the probe sticking up through the floor of the sump, next to the Water Indicator which you changed.

    It’s HERE if you wish to proceed with the repair. Be very careful – do not get any part of it wet whilst changing it.

    Power off, of course.

    Thanks for the reply
    I actually did not change the water indicator, as the problem disappeared after letting the machine sit unused for about 3 months.

    I spoke to a local Whirlpool repair guy who suggested it may have gotten stuck mid cyle and leaving it sit let it “relax” out. Sounded a bit off but machine did start working fine again for about a month. Now I have this new problem…

    Should I now change both ?
    Am slow to work on it as it is built in tight into kitchen unit.

    You might get away with giving the Water Indicator a good scrub out with very hot water and and old toothbrush – you can usually see the coagulated fatty deposits through the black grid.

    The NTC or temperature device there’s no way round. They are particularly touchy beasts and either work or don’t – no half measures I’m afraid.
