Dishwasher won’t start. Panel lights work. I press (Normal Wash), (Heat Dry) and (Start/Resume).
1) I can hear water softly running.
2) After a minute or so, I hear a 1 second long buzz that repeats every 5 seconds for a half a minute or so.
3) Then the cancel/drain light comes on solid. And, water is draining into the garbage disposal.
4) After 30 seconds or so, all the lights go out.
I reset everything by shutting off the circuit breaker. No change.
I think maybe the Float mechanism or switch is bad, so I remove the float and everything is very clean and free. I remove the switch and check it with a meter and it is fine.
So, what do I do now? Could it be anything else other than the control board?

Hi. I have seen this issue before on this unit. From what you have described it sounds like you have a bad motor/ pump assembly. The noise you hear after the unit fills is the motor running for the wash potion of the cycle, but is does not sound normal because its not rotating you wash arm or spraying any water. Then the control board senses no rotation and cancels the cycle. You could also have something in the sump blocking the impeller from running. I would check this first. Something in the sump is broken between the motor and impeller. You could tear it down to see what has broken and replace it or replace the whole assembly. Attached is a link for the motor sump and a video showing how to check for a blockage in the motor sump. Please let me know if you need any further assistance.
