What HC means

On current Dacor Modernist and Contemporary dishwashers, such as the DDW24M999US, DDW24M999UM, DDW24T998US and DDW24T999BB, HC is a high temperature heating check. The control found the heating in the tub running hotter than it should, so it stopped the cycle and showed HC. You see the code on the display and the wash does not finish. The owner's manual lists a simple retry before calling for service.

Common causes of HC

Heating element or its control circuit staying on too long
Temperature sensor in the tub reading incorrectly
Control board that is not switching the heater off

✓ One safe check you can try

1. Let the dishwasher cool, with the door closed. 2. Start an empty cycle with detergent, as the owner's manual lists. 3. If HC appears again, switch the dishwasher breaker off. 4. Do not use the dishwasher until it has been checked. 5. Call us and tell us the model number and when the code appeared.

! Why to stop there

An empty cycle that clears HC once does not prove the heating circuit is safe, so we test the heater and sensor readings.
Heat that is too high can come from a sensor or from the board, and the code does not say which.
We give a written price before work, and the repair carries a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

HCHC questions

What does HC mean on my Dacor dishwasher?

HC is a high temperature heating check. The control sensed more heat than the cycle allows and stopped it. You see HC on the display and the wash is not completed.

Should I run the dishwasher again after HC?

One empty cycle with detergent is what the owner's manual lists. If HC returns, switch the breaker off and leave it off, because repeated overheating is not something to test at home.

Is HC dangerous?

It is a protective stop, so the machine is doing its job. But excess heat should not be ignored, so if the code repeats we want the heating circuit tested before you use the dishwasher again.
