Dereck for Model Number 665.12773k311 I have a Kenmore (rebranded Whirlpool) dishwasher. The heater wasn't heating the water or drying at the end of the cycle. I found the filter screen was plugged with cooking grease. I cleaned the screen. The issue remained. In advance, I purchased a new heater coil and thermostat. I pulled the unit and removed the heater coil and thermostat. I did a continuity test on both parts and they tested good. Please indicate what to test next. Could the Turbidity sensor be bad. I believe there is a thermal switch in that sensor as well. I'm stuck.
Answer Hello Derek, it sounds as if the control board has disabled the heater circuit. It can do this if it sees certain problems unrelated to heater operation, You will need to run the diagnostic test to find the fault code, the diagnostic test sheet is located behind the lower kickplate. To enter the test, open the door, cancel any cycles, press any 3 keypads in a 123.123.123 sequence, close the door and count the clean light blinks. That will be the fault codes, can have up to 4 codes. Read More... Answered by AppliancePartsPros.com | Monday, November 18, 2019
