Quick answer
Samsung dishwasher HC: interior temperature is too hot or fails the high temperature heating check.
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
High temperature heater error: interior is too hot (US); high temperature heating check (AU).
HC on a Samsung dishwasher is a high temperature code for current models. Samsung’s US page describes it as the inside of the dishwasher being too hot, while the Australian page calls it a high temperature heating check.
The US steps
Switch the dishwasher off at the circuit breaker for 30 seconds and then back on. Empty the dishwasher, fill the detergent drawer and start a Normal cycle. If HC appears again, request service.
The Australian steps
Run a cycle with the dishwasher empty and detergent added. If the code continues, turn the dishwasher’s circuit breaker off and contact a service centre.
