I have a Whirlpool dishwasher (type 575-0). Over the weekend, the dishwasher control buttons simply stopped working. No LEDs came on when the button was pushed, dishwasher didn't start, nothing.

Yesterday I disassembled the dishwasher, reset all the connections, and clean up the door switch. After reassembling the dishwasher and turning power back on, exactly one light came on (the sani-rinse). Thinking it was just the lights, I pushed start and when I closed the door, there was a mechanical grinding sound. I don't think it was the integrated disposal, it sounded more like a pump or valve. It definitely didn't sound good. After that happened, the board was once more dead. After resetting the power, again the single light. I tried putting it into diagnostic mode, but nothing happened.

Does this seem like a control board issue? With the odd sound, I'm wondering if one of the pumps/values is causing a problem that breaks the controls. The control board costs 1/3 of the amount of a new dishwasher, so I'm not going to replace it unless I know that is the problem.

Does anyone have any ideas on what the issue could be?

  • Sounds like a bad logic board. – Tyson May 25 '16 at 18:08
  • wild guessing: could be something shorting out (tripping a shutoff); could be a fried circuit or a bad other board. Either way, probably time for a new dishwasher if this one is already several years old. – DA01 May 25 '16 at 18:15
  • A short seems to have won the day. This afternoon I started smelling burnt plastic. After shutting off the breaker to the dishwasher, it went away. I'm hopeful that the short isn't in the wall, but is instead in the dishwasher. – Erick T May 26 '16 at 4:21

After smelling burnt plastic for a few hours, I can safely say it was a short.

    A pump that is stuck will draw locked rotor current , this is much like a short and will cause the burning smell as the windings over heat. – Ed Beal Sep 6 '17 at 17:17
  • Possibly something stuck in the grinder, or a stuck water pump (as Ed suggested)? Also check for a stuck float switch. It sounds like the washer thinks there is still water that needs to be drained but the pump can't turn for some reason. – Eric Simpson Dec 4 '19 at 13:55
