HC explained
This is a high temperature code on current models. In the US wording the dishwasher interior is overheated; the Australian listing instead calls it a heating check for high temperature.
US procedure
Flip the circuit breaker off for half a minute, then back on.
Unload the tub completely.
Put detergent in the drawer.
Launch a Normal cycle.
A second HC means requesting service.
Australian procedure
Australia asks for a cycle on an empty dishwasher with detergent in. When the code stays, put the dishwasher’s breaker in the off position and get in touch with Samsung service, leaving it off until then.

Model compatibility: Samsung 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

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.
