Kevin K for Model Number GSD4000J00WW Does not drain completely. The drain solenoid tests good. Mine does not have a check valve or piston assembly. If I disconnect drain hose at insinkerator, dishwasher drains almost completely into a bucket except for about 1/4". I pulled insinkerator and all drain pipes out and there doesn't appear to be any blockages. Both sinks drain fine. I did notice that when I pulled the motor/pump assembly out that the rubber flapper attached to solenoid arm is chewed up a bit and allows some water to shoot back in the tub during drain. Any help would be appreciated. Thanks
Answer Hello Kevin. If you are sure the drain hose is not clogged, you will need to replace the complete pump and motor assembly WD26X10013 in the unit. Read More... Answered by AppliancePartsPros.com | Wednesday, September 11, 2013
