High Limit Thermostat WP661566

Hello Ashley, thank you for contacting us. It could be the high limit thermostat, it could also be the heating element. You can test these with a multi meter. Good luck with the repair!

Hello Frank, Thank you for the question. The thermostat should read closed at room temp. You can test this with a multi-meter. Hope this helps!

Hi Brad, Thank you for the question. The drain hose may not have a loop in it. The fill water may be draining out of the dishwasher by going straight out the drain hose. Be sure that your drain hose is not simply laying straight. It must have a loop in it or be off the ground so the water is not gravity fed out via the drain hose. You can also try to empty the dishwasher, set it to run a wash cycle. Let it fill with water as normal. When the dishwasher begins the cycle, open the door and see if the water level is just under the heating elements.If there is not enough water there may be a clog in your water fill line. Remove the fill hose where it attaches to the fill valve. Check to be sure there is nothing clogging the screen on the inlet fill valve. Also check the water fill line for blockage. You can also check the Overfill Control Switch if it is not filling with water at the correct level. If it is defective it can shut the water flow off too soon. Hope this helps!

Hello Drew, Thank you for your inquiry. I would also check the bi-metal fuse/thermal fuse, door switch-and wires going from it to the control board, and the control board itself. Hope this helps!

Hi Josey, Thank you for the question, the flashing sanitize light indicates it did reach the sanitize temperature of 140-155 degrees in the final rinse. You can try running the hot water in the adjoining sink to get the hot water up to max temperature before starting the dishwasher. If this does not help try opening the door a bit during the wash cycle to see if there is steam indicating the water is hot. If the water is not getting hot then you may need to replace the heating element. Hope this helps!

Hi Bahman, Thank you for the question. This part is used as a safety device to protect the dishwasher circuit from overload. If the temperature gets to high it will shut off the electrical current to the heating unit in the appliance. Hope this helps!

Hello Richard, thank you for your question. If there is water getting into the unit but the appliance will not start the cycle you will want to test the motor to see if it has failed. If the motor is fine, the issue would be with the electronic board which would have to be replaced. I hope this helps!

Hi John, That is a good question. It may cause the situation you are describing. Another part that may fix the issue could be the door switch kit as well. You may need to contact Whirlpool for more information. Their telephone number is 1-866-698-2538. I hope this helps. Thanks and have a great day!

Hi Bahman, Thank you for your question. Well, if both your heating element and your thermostat are testing that they are working, then the only other parts to check would be your bi metal fuse, and your electronic control board. I hope that helps. Good luck with your repair.

Hello Chris, Thank you for your inquiry. Since the high limit thermostat will shut down the heating element once it reaches a certain temperature, it could be causing the issue. You can test it with a multimeter to see if it has continuity. I would also double check the wiring going to the heating element for any visible damage. Hope this helps!
