New GE Dishwasher wont stop draining

I pulled this out of a newly constructed house because the owners went to stainless. It had water in it so I believe it was run or tested. I just installed it in a friends home and it works but it seems like something might be stuck in the drain. It fills and when it kicks into wash mode, the water just pumps out the drain. Any help? Thanks a bunch!

Could not find info on this particular unit, hopefully the following is close.[COLOR=Blue]

Check out the pump.

On the left hand side of the pump housing you will see a solenoid.
This operates the wash/drain flapper valve.
Up is for wash
Down is for drain.

The way it works is that at the start of the drain cycle the solenoid gets power for about 10 seconds. This pulls the solenoid plunger/flapper down into the drain position. The water pressure then holds the flapper valve here till the unit is empty (no more water pressure on the flapper). The springs on the solenoid’s lever arm then return the flapper valve to the wash position.

Perhaps your flapper is stuck in the drain position or the springs came off during the move.

Also be sure that the drain hose is looped up at least 10 inches higher than where it enters the house plumbing.

I was watching the solenoid and there is not much movement when it is going up and down. I am going to take it apart and see if something is stuck in it. Thanks again, AL
