[FIXED] Maytag Dishwasher humming motor, drains, and shuts down

Model Number: W10596270A
Brand: Maytag
Age: 1-5 years

I started my dishwasher the other night and heard the motor humming. I left it assuming it would go and went to bed. My wife told me she started, and I had forgotten to (It figures). Her cycle did not finish either, and she noticed the humming as well. I ran the diagnostics on it and got codes 4-3 and 10-1 back in that order.

4-3 is No communication between the electronic control board and the wash pump motor (No surprises there with the humming).
10-1 is Dispenser electrical problem.

When I ran the diagnostics I didn't get a hum at all, so I don't know if it tried the motor or worked fine. I can hear a click before the motor starts humming and before it stops, so I assume the relay is working fine. I know the dispenser works because it opened during the diagnostics. I am going to try inspecting and cleaning the impeller tonight. Is there any way to work out what is actually causing it not to start?

It seems like deep cleaning the impeller fixed the problem. It started right up after I got everything put back together.
