May 14, 2023 I have the same problem, replaced the drain solenoid and it burned up. I always thought this was caused by the timer, so I have one ordered and an another solenoid. My dishwasher is a GE, and going on 9 years old. I thought about replacing the dishwasher with a new one, but at about $600 plus I thought I would try repairing the old one. So far I have about $150 in parts.

I'm not so sure it's the timer's fault. I got a work order in for a dishwasher that won't drain.

Funny thing is when I got it, it wouldn't fill or drain. The water inlet valve was stick closed, and the drain solenoid was melted closed.

I installed brand new parts. The water goes in and goes out half as fast.

Confused, I check the solenoid. It was binding about 2/3rds the way in. I tried WD40 and it improved the movement, but did nothing for the binding.

Perplexed, I inspect my brand new part from GE and I notice that the actuator (the metal part of the solenoid) is milled to for the home perfectly.

This is not good, because the hole is a plastic columns and the metal bottom is air tight. Thus condition causes a vacuum resistance when the spring tries to pull the actuator back out of the coil. Think when a full trash bag is difficult to remove from a trash can.

So, I took a file and filed down the bottom half of the actuator so air can get pass.

That solved the binding issue

After making the modification, I now wonder if I could have taken my Dremel and just made a single shallow notch from the bottom to the top of the actuator and achieved the same result.
