Customer Questions and Answers for Water Inlet Valve Assembly by Whirlpool

Hello Tom. It uses a thermistor and this is the way the manufacturer designed the washer. It is working properly.

Hello Chad. It sounds like the timer WPW10111389 and the water valve WPW10144820 is bad and will need to be replaced in the unit.

Hello Johnny. 1. Unplug washer or disconnect power. (also disconnect the fill hoses) 2. Slide a putty knife under the right or left corner of the control panel. Lift the corner of the panel and push back on the knife blade to release the clip. Repeat the procedure for the other clip. 3. Rotate the control panel and position it back out of the way. 4.Lift the locking tab, and disconnect the main harness from the lid switch connector. 5.Remove the 5/16? hex-head screw from the green ground wire on the lid switch. Lift the washer lid so it is straight up. Release the locking tab and pull the lid switch up and out of the cabinet top opening. 6. Use a screwdriver and unclip the left and right cabinet spring clips from the cabinet top. 7. Rotate the cabinet up in the back and slide forward so you can access the top of the tub, and set the cabinet aside." You now have access to the fill valve assembly Use a flat blade screw driver and remove the plastic mounting pin, and disconnect the tabs in the assembly from the slots in the cabinet back, disconnect the wires and reverse the procedure to install the new valve assembly.

John, The way to test is to check the water temperature. Let the tub fill with water and the temp should be 78 degrees on warm and 105 on hot. While it is possible that the thermistor is not working properly, it would normally have issues with the cold water fill as well.

John, your washer is an "energy star" machine. It has always had a "Target Temperature" : Hot water temp 105-110 dgrs.F, warm water temp. 78-92 dgrs.F. and cold water temp. 62-70 dgrs.F. (+/_ 10%) Only one of the cold water temp settings is un controlled ( whatever the cold water temperature out of the faucet is what will fill the tub). In some areas of the country, the thermistor can be slow to react due to the extremely low cold water temp.(northern climates) or the warmer cold water temp (dessert climates). The water temp. thermistor is actually part of the fill valve / flume assembly WPW10144820 and as long as you have good water flow through the assembly, the thermistor will react properly. You may want to start a wash cycle and check the water temperatures entering the tub with a cooks pocket thermometer. This will help determine if there is an issue.
