My dishwasher has stopped working. It was running fairly loud for a few days, then stopped altogether. (I know, I know, should have stopped and investigated sooner but with the holidays, etc I just stuck my head in the sand and ignored it).

I found some small fragments of glass in the grinder and I suspect that's the cause of the problem. The impeller does rotate by hand but not very freely.

Running a rinse only cycle now results in the following:
Machine fills with water.
A "click" and then hum (sounds like motor is trying to turn on but is stuck). Afer a few minutes, the drain pump comes on and drains the system. I noticed that the main motor is very hot.

I don't have experience working on these things but I think I have enough mechanical skills to do the job. The question is, what needs to be replaced?

Any advice would be appreciated.

Thanks for the reply. Isn't it possible that after replacing the motor the machine will still be running loud due to a bad pump? I was thinking maybe I should just get the complete pump and motor assembly (item 14) for $60 more and be assured that everything is good.
