Jodie for Model Number GSD5330D01WW Dishwasher does not drain. Piston and nut assembly check valve is shot (AP2617344)...cone has discinerated. Could this be the problem? Pressing start and reset used to drain pan, but problem continually got worse and now no longer drains at all. Drain lines, connection at disposal, screens, sumps, etc. all cleaned and clear. drain pump runs (bench tested) and cycle tested, and drain pump impeller is clear. Also, replaced valve flapper (328). Recently replaced motor pump complete due to small leak at shaft dripping onto solenoid (was still working but water was getting on the floor), so none of the above is the problem. Restating Question: If piston and nut assembly check valve is bad, is this the problem for dishwasher not drain?
Answer Jodie, Yes the piston and nut assembly WD24X10018 being defective will cause the unit to not drain. Read More... Answered by AppliancePartsPros.com | Thursday, December 22, 2016
