Whirlpool wdf520padb dishwasher fills, then I hear a (quiet) click-whirr, which repeats every four seconds for about 30 seconds, then the unit stops.
BTW, I believe this unit has a diagnostic mode, which I can trigger by clicking any three buttons three times in a row. When I do this all the LEDs come on, and then just three come on. But I don't have the diagnostic paperwork that's supposed to be in the plastic sleeve inside the kick cover. I must have... "filed" the papers somewhere. If anybody has a copy or can direct me to one online I'd be grateful.
