HC explained
Among the information codes in the Dacor manual, HC stands for a high temperature heating check. It belongs to the current 24-inch Modernist and Heritage dishwashers (DDW24M99* and DDW24T99*) and is displayed when the machine fails to run.
What the manual wants you to do
Load nothing, put in detergent, and start a cycle; the manual describes this as a functional check.
Should HC remain on the display, find the home breaker panel and turn that dishwasher’s breaker off.
Next, get in touch with Dacor.
Other information codes
LC signals a leak, PC is the zone wash function check, and F9 is an older-series WPS sensor label.
Dishwasher service in San Francisco
When HC returns, call (415) 687-5926. Tell us the code, the model number and how the empty cycle went. Dacor dishwasher repair covers San Francisco and the Bay Area.
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
HC is the high temperature heating check information code; the manual advises an empty detergent cycle first.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
