What Does Monogram Dishwasher Error Code C2 Mean?

Error code C2 on a Monogram dishwasher signals a fill valve problem — specifically an overfill or continuous fill condition. The control board detects the water level is rising beyond the expected point, suggesting the fill valve is not closing properly.

Common Causes

  • Stuck-open fill valve – The solenoid valve fails to close after the tub reaches the correct level, continuously adding water.
  • Faulty water level sensor – Incorrect level readings cause the controller to keep the valve open too long.
  • Control board fault – The board fails to send the close signal to the inlet valve.

How to Troubleshoot

  1. Turn off the water supply – Close the shutoff valve under the sink to stop water flow.
  2. Reset the dishwasher – Press Cancel/Drain, wait for the pump to clear water, then cut power at the breaker for 60 seconds.
  3. Observe on restart – If the tub continues to overfill after reset, the fill valve needs replacement.
