What is this dishwasher drain solenoid seal part & how can I replace it?

Our dishwasher (GE GSD3200G00WW) is leaking underneath whenever the drain process kicks in. It looks like the seal between the drain solenoid and the drain itself has deteriorated and should be replaced.

Removed the drain solenoid:



This part (1/2 inch in diameter) (that is right against the drain around where the shaft comes out) popped right off:



And behind it you can see rotted rubber type material inset into the drain itself around the shaft:



which is almost certainly where the water is coming out.

In the videos I can find showing how to replace the drain solenoid, it shows this part already being in place, as if built into the drain itself, for example in this video https://www.youtube.com/watch?v=1ZX9uP8UcPc#t=96 :



So -- what is this part called? And, how can I replace it? Can I just scrape out the remaining rubber from the drain around the shaft, and then pop the new part in? Or is this so integrated with the drain that I'll need to fully remove the drain and pump and everything?

 

Post make and model # before somebody can help.

 

Welcome to the forums.

Oh, duh, dishwasher is a GE GSD3200G00WW - sorry

 

PJmax - thanks! that video is exactly what I needed. https://www.youtube.com/watch?v=3kamDdLlWSs

Tinnerman clip is the metal piece that is 1/2" diameter
Shaft seal is the rubber part and can be popped right out.

Even though the dishwasher in the video is not a GE, the actual drain and solenoid and whatnot look exactly the same, so the part numbers might even be correct.

THANKS!
