Impeller ... gone!

Dishwasher Repair
1

I have a whirlpool dishwasher. It quit working today. I just took it apart, and I can see that the impeller blades are all missing. I can’t tell if they were knocked off, or eaten away. There seem to be no pieces floating around inside, and the motor is working.

No leaks.

So, I see that impellers are only, like, $20.

2 questions:

  1. How do I get the darned thing off the motor shaft?
  2. I see the impellers (PN: 3108052) are out of stock - how soon can they be delivered if I order now?
  3. (I can’t count) - what else should I get to ensure the repair is good?

Got it off. Didn’t break anything. Still - how long to get a new one? And what do you suppose happened to it?

I was looking for info for you but could not find anything decent on pump repair but perhaps the following will be of some use.

As to what happened I can only guess. Something could have got in there, ate up the fins and then once they were gone was able to get out.
I would check the drain assembly just in case it is now stuck in there.
