Whirlpool dishwasher stuck in rinse. Water heating light is on. Water is hot, but dishwasher continues to run. Cycle completes in low energy / China, but on Normal or higher does not drain / advance.
I think it is either the hi limit or the operating thermostat.
Can you tell me which?
Hi limit is AP3010530,
Operating / Cycling is AP3115144
Thanks,

The first failure suspect is the cycling thermostat AP3115144. The hi-limit thermostat is a safety device to prevent overheating. Here are the break down diagrams for the whirlpool dishwasher Model DU920PFGB0Gene.

And here is the tech sheet and wiring diagram https://www.servicematters.com/d...0Sheet%20-%208066008.pdf https://www.servicematters.com/d...0Sheet%20-%203379193.pdfBuy a meter otherwise you are guessing and so am I. You can get a decent digital multimeter for under $20.00, you do not need fancy though it is nice if the leads are a couple feet long. You can then check the heater for resistance (usually around 25 ohms) and the thermostats (should be 0 ohms at room temperature). There is a good sticky on meter usage at the start of this forum Maybe it is heating but the unit does not sense the temperature increase. |
