Dave for Model Number GSD3620F00BB My dishwasher does not seem to properly drain out completely before the water valve opens. I studied this forum, then I 1) opened the washer's sump and checked for debris - found none 2) replaced the drain hose from the drain check valve in the kitchen sink to the dispose-all - water runs free 3) opened the bottom panel and watched the operation and checked off the drain valve circuit closure per the maintenance sheet I found attached under the unit 4) found that the drain solenoid functioned when the circuit closed during operation, BUT!!!...when the circuit opened, the drain valve was still forced in the DRAIN position by the pump pushing water out the drain....I assume the valve closes when the pressure drops upon the sump draining dry...but it never does! (to check this, I simply opened the door to stop the pump, and the drain valve closed back to the normal (pump flow to the washer) position). 5) The timer then moves on and opens the water valve and on to the next cycle it goes. OK, what do I do next? Purge (somehow) the drain line to the sink? What is causing that valve to stay stuck in the drain-out position once the solenoid de-activates? Is the pump too weak to get the water out "in the time allotted" or is there an obstruction keeping the pressure in the drain-out path too high for the springs to pull the valve shut? (I could not close that valve by hand until I opened the door and stopped the pump, then it shut on its own) Just to reiterate, the solenoid is working per the schematic - but the valve won't close with the pump running. I can move the valve freely by hand when the dishwasher is off. thanks Dave
Answer Hello Dave. You will need to test and see if power is coming to the solenoid during the drain cycle. If so, but the solenoid does not engage, you will need to replace the solenoid WD21X10268. You can test this with a multi-meter MA-DM1. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
