What Does Monogram Dishwasher Error Code C3 Mean?

Error code C3 on a Monogram dishwasher indicates a wash pump malfunction. The circulation pump that pressurizes water through the spray arms has failed to operate correctly, resulting in poor washing performance or a complete wash failure.

Common Causes

  • Blocked pump impeller – Broken glass, food debris, or foreign objects jammed in the pump prevent it from spinning.
  • Failed wash pump motor – The pump motor has burned out electrically.
  • Loose wiring connector – The electrical connection to the pump motor has come loose.
  • Control board fault – The board’s pump drive circuit has failed.

How to Troubleshoot

  1. Check for debris – Remove the lower spray arm and filter assembly. Look for glass or hard objects near the pump inlet and remove any found.
  2. Clean the filter – Rinse the cylindrical and mesh filters under running water.
  3. Reset – Cut power for 60 seconds and restart a short cycle.
