    Went to a W’pool dishwasher ADG7540 (8542 5401 5810) that was not heating the water, otherwise seems to run OK.

    On the diagnostic all I got was a continuous flash – someone said this is actually an F1 = NTC Fault? Is this right?

    Anyway the resistance cold on the NTC was 13.8 K ohms.

    Can anyone tell me if this is a correct or incorrect reading. I have ordered a new NTC anyways.

    Thanks

    As a rule anywhere between 10 & 20KΩ is OK. 🙂

    Here are the correct values for Whirlpool dishwasher NTC’s

    20º = 58.1 kΩ
    25º = 47.1 kΩ
    30º = 38.2 kΩ
    40º = 25.4 kΩ
    50º = 17.2 kΩ
    60º = 11.8 kΩ
    70º = 8.3 kΩ
    80º = 6 kΩ
    85º = 4 kΩ

    Thanks John

    Fitted the little bayonet-type NTC probe and D/W is now heating properly.
