Paul M. for Model Number WDF530PLYB1 Replaced broken heating element on Whirlpool Dishwasher Model # WDF530PLYB1. Easy enough. However, the dishwasher runs through all cycles but heating element doesn't come on. Do not think this newer dishwasher model has a separate heating element thermal fuse but instead a thermostat that may be preventing the heating element from comming on? Any advice? Thank you.
Answer Hello Paul, The thermostat WP661566 is under the unit mounted to the bottom of the washtub. To test it, remove one wire and test from one side to the other. If bad, it will not give a reading on your meter at all. If it is good, it will read just like you were touching the two meter leads directly together. You can test for an internal short by removing the other wire and testing from either terminal to a known good ground. If the thermostat, heating element and wiring all test good, you will need to replace the control W10473200. Read More... Answered by AppliancePartsPros.com | Thursday, March 7, 2013
