Customer Questions and Answers for Water Inlet Valve (Dishwasher) by Whirlpool

Hello Pat in Tinley Park. This model uses a thermistor and mixes hot and cold no matter the setting. Make sure the wiring connections are good. It could be a bad temp switch WP8578337.

Irock, The water valve WP8578341 is the correct water valve for your unit. The yellow connector is for the thermistor for automatic temp control.

Hello Gary, This will either be the water inlet valve WP8578341 thermistor or the temperature switch WP8578337. The thermister cycles the hot or cold mixing valve of or back on to control the water temperature.

Ron, It could be the fill valve, but first check and make sure the fill hose and fill valve debris screens are not clogged. Make sure your hot water temperature is 120 dgrs.F. and your cold water is not too cold. Any one of these issues could cause the washer temperature to fluctuate or exceed the bi metal switch perameters.

Hello Frank. If you can stop the water from entering the machine by turning off the timer or unplugging the unit, you will need to look for a bad pressure hose or replace the pressure switch. If the only way to shut off the water is at the shut off for the water hoses, you will need to replace the water valve WP8578341 in the unit.

Al, Your washer is probably operating "normally". The water valve WP8578341 has a thermistor or bi metal installed in the water flow. Based on the temperature selected, the water valve cycles the hot and cold water solenoids off and on, in an attempt to reach the prescribed water temperature. A quick, easy check, fill the washer on a hot wash setting,take a thermometer and set it in the water for a few minutes, the water temperature in the tub should be in the neighbor hood of 110 dgrs. F. +/- 10 %. If you're in that range then the washer is working properly. Thanks and Good Luck

Hello Rick. Based on the information you provided, it sounds like the water valve WP8578341 is bad and will need to be replaced. Hope this helps.

Hi Don. The water valve is part # WP8578341. Did you take the hose off and try to put it in a bucket to insure the water house supply valve and hose is not clogged? It should take a professional well under an hour to remove the cabinet and access the valve. Thank you.
