My dishwasher won't heat the water and seems to run a loooong time. 2 hours. I checked the element and it tested good. I checked the thermister and it tested 39000 ohms.
There are no blinking lights, and I had the dishwasher set at high temp wash, high temp rinse. the water never heated. What would be my next step?
ANSWER Hello Tim. Based on the reading you got, the thermistor in the unit is bad and will need to be replaced.
