Questions & Answers

For Whirlpool Thermister (Part Number: OEM18036888)

1 Answer

Linda, No there are no "special" tools needed to replace the WP8269208/WP8269208 Thermister. Here's a little help " The thermistor can be removed from the sump by turning it ¼ turn counterclockwise and pulling it out(make sure the power to the dishwasher is removed, have a couple of rags handy to catch any water that will leak from the sump). The thermistor can be removed without removing the sump assembly from the tub. Access to the thermistor can be gained by removing the access and toe panels while the unit is in its installed position. Thanks,

Gary, Remove the console and the control board from inside the console. If you find a black or dark color substance in the membrane switch [green harness on control] then it is shorted and would need to be replaced. The part number would depend on the color.

Hello Tim, There are three more parts in that circuit. These are the door switch WPW10653840, the control board W10854220, and the wiring harness W11027902. These should all be checked to determine the issue. Be aware also that if the unit is not properly leveled and secured under the countertop, the door switches may not be "making" electrically when the door is closed.

Tim, For a proper diagnosis, we would need you to please verify the model number from the units' I.D. tag since it will not come up for us as a valid model number.

Terry for Model Number 665.17059402

I have a Kenmore Elite Dishwasher that stopped working after the wash cycle. It would pump out, but the rinse cycle wouldn't start and the control buttons locked up. I replaced the main control board but that didn't solve the problem. I have completely gone through all components checking resistance, continuity, freedom of operation, etc. and all checked out fine except the wax motor (vent) resistance is about 25% high. I don't believe this is the problem. I thinking thermistor even though the resistance was right on at room temperature. Do you have any thoughts on my problem and would you have a temp/resistance chart for the thermistor (Part # WP8269208) Thank you. P.S. My incoming hot water runs hot about 160 degrees F.

1 Answer

Terry, your incoming water temperature seems rather high. Thermister readings at 77 degrees is 48-52K, as it gets hotter, the resistance number drops, at 140 degrees it should read 12-13K. Have you tried running error codes on the display? Sometimes a thermister will read good at room temperature but once it heats up, the numbers can be off.

Peggy P, the thermister is located on the sump/motor assembly. It should be possible to replace it without removing the dishwasher, but, it would be easier to pull it out and work on it.

Oliver, According to the parts list of this unit it will not have a thermister in it. If there were a thermister it would be located on the bottom of the sump assembly.
