Mend GE GSD4020Z07BB Dishwasher Leak Pump

GE GSD4020Z07BB Dishwasher will not completely drain?

We've noticed an occasional leak near the door over the past few months, then we noticed this past week the pan was full of clean water. Apparently it is not completely draining.

I disconnected the strainers and made sure it was free of garbage, then disconnected the drainage hose and blew air through it to make sure it was clear of a blockage, along with the pipe it was connected to.

Are there any repair instructions available online for checking the pump and parts associated with draining the dishwasher? I have hit end of my knowledge of how to repair a dishwasher.

Thanks!

I had a similar problem when my dishwasher was about two years old. I found that the piston valve was corroded and did not seal when activated, allowing water to come back into the dishwasher when pumped out. To check this valve, remove the filter screen in the very back of the inside of the dishwasher. The piston valve is right below the screen and can be unscrewed with your hand. If it appears defective - replace it. This fixed my problem.

I wish I knew the answer as well. My GE GSD5120D00BB dishwasher does not completely drain either. I first noticed this in December 2005. Any clues? I saw some answer online that it might be an electronic timing component which turns the pump on for a set period of time.
