Last week the heating element in my dishwasher quit getting hot. I ordered a new element and installed it into the dishwasher two days ago. The new heating element did not fix the issue. I then removed the thermistor and tested it with my multimeter. It looks like the reading is 44k Ohms if I'm reading it correctly. I have no idea if the thermistor reading is within its operating limits. Unfortunately, the service materials and wiring diagrams are not still with the dishwasher. The dishwasher appears to be working fine except for the heating issue.

Are there any other items I should be checking? I can't find any definitive service documents on this old model.

Thank you

Hi RT,

The thermistor should measure 5K ohms at room temp. So if it was 44k ohms at room temperature its way off and that is likely the problem.

Here's the thermistor for your model:

I replaced the thermistor today with a new one but the dishwasher and element are still not getting hot. Is there another item I should be checking?

That's odd, the thermistor was way off too, unless your meter wasn't reading it properly.

The only part left that tells the heater to come on is the control board.

Here's the control board assembly for your model:
GE WD21X10247 Main Control Board Kit


The resistance plug (selector plug) from the old board (location @ CN4 on the board) must be connected back on the new board.
