Chosen Solution
I have a Whirlpool Quiet Partner II (W10142800B). A week ago it started running dry through the wash cycle. The dishwasher fills normally during the soak, sprays water fine during this cycle, the float switch works, then when it dispenses the cleaning solution it drains all of the water and runs the rest of the cycle dry.I have already replaced the Circulation Motor, Drain Motor, and Inlet Valve switch with little change. There was some debris near the chopper screen and all of that was cleared out. Whoever originally installed the dishwasher used copper pipe to connect the inlet valve, and it had a kink in it. I replaced this with a flexible pipe, with no change. If I manually fill it during the wash cycle, it runs fine until rinse where it will run dry. I can hear the drain motor running when it turns on, sometimes with a rattling noise (maybe the rubber drain valve?)The only remaining parts to check would be a bad connection or capacitor, maybe the sensor. I’ve looked all over the forums and found similar issues but not many with solutions. What is should do on Normal is FILL - WASH - DETERGENT -WASH - DRAIN - FILL -WASH - DRAIN -FILL- Heat WASH - WASH - DRAIN - DRY What is is doing is FILL- WASH - DETERGENET - DRAIN - WASH (dry) - DRAIN - Sometimes fill…. Dishwasher fills initiallyWater sprays fine during cycleInlet valve screen clean and newChopper screen cleanDrain hose is above the fill hose by 30 inches.Both motors replacedNo damage to any parts of the motorno objects in the motors or drain areafilters are clea
Unfortunately, most of what you have done would have little chance of causing this problem. Water is input so it can’t be the fill valve. The water drains so it can’t be the drain pump/motor. One of the cycles pumps water to wash/rinse so it cant be the circulation motor or drain valve. If it is being told to drain prematurely, it must be a problem with the control bd.
