What HC Means
HC is the heating check on current Dacor dishwashers. Dacor calls it a high-temperature heating check and has the owner run a functional test before calling for service.
Common Causes of HC
- Heater or its thermostat failing
- Temperature sensor reading incorrectly
- Incoming water much hotter than specified
🔧 One Safe Check You Can Try
With the dishwasher empty, add detergent and run a cycle, as Dacor instructs. If HC appears again, switch the dishwasher’s breaker off and contact service.
⚠ Why You Shouldn't Go Further Than That
- The heater and sensor sit in the sump or under the tub, reached with the dishwasher out.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
