KDP-20 Problwms Hi carl, The drain pump and the main motor are the same thing on your DW, then there is a drain valve that opens while the main motor is running which allows the water to drain when called for by the timer.
I am wondering if just the main motor is staying on and or is the drain valve also staying on as well ? [ When it is stuck in the cycle open the door and poor a gallon of water in the DW and see if it drains when you start the DW again right away ]. Also if you think the drain valve is staying on ? or it might have something stuck in the valve that is holding the valve open causing the DW to appear to be getting stuck in the drain mode [ very likely ]
Do some more checking out and let us know what you find.

Melted Drain Solenoid Yay Glad You got it working great news.
These Solenoids are intermittent duty coils, if they are energized more than a few minutes they melt and fail,
They can also just short and fail on their own as well, The failure was not caused by a voltage drop and the only way a timer can cause a failure is if it keeps the coil energized too long, so if the timer caused it the new part would have failed by now.
