Error codeHC
ApplianceDishwasher
Quick answer
HC on Dacor Modernist and Heritage dishwashers is a high temperature heating check; run an empty cycle with detergent.
Model compatibility: Dacor reuses codes across series and model years, so HC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
High temperature heating check.
HC on a Dacor Modernist or Heritage built-in dishwasher (DDW24M99* and DDW24T99*, 24-inch) is the high temperature heating check. It is one of the information codes in the owner’s manual, shown when the dishwasher fails to operate.
Steps from the manual
Empty the dishwasher, add detergent and run a cycle. The manual calls this a functional check.
If HC continues, go to the circuit breaker panel and switch the dishwasher’s breaker off.
Then contact Dacor.
