As the title states, the dishwasher won't drain. I've taken the inside sump apart and found some junk in the screen - cleaned all that out. Impeller spins freely. Verified that the hose is not kinked or blocked, and the sink it connects to drains. I suspect that the pump or control module is the culprit - which connector on the control module goes to the pump? Does anyone have the service manual for this dishwasher? Any other suggestions? Thanks.
