Samsung Dishwasher Error Code HC: High temperature heater error
Applies to Samsung dishwashers that show HC or 1E, IE on the display.
The heater is running too hot or its control has faulted. On rotary models this same error displays as 1E or IE.
What this code means
The dishwasher heats its own water for the hot wash and sanitize phases. This error means the heater circuit reported a high-temperature fault. Rotary models display the same fault as 1E/IE.
The manufacturer's checks, in order
- Reset the dishwasher: switch its circuit breaker off, wait a moment, and switch it back on.
- Run a cycle and see whether the code returns.
If the problem continues after a reset, switch the breaker off and contact a Samsung service center.
