# Samsung dishwasher error code HC

### What HC means on this make

The machine has measured the temperature inside the tub and found it too high. That is either the heater staying on when it should have stopped, or the sensor reading low and letting it. Samsung’s own first move is a full power cycle at the breaker and a normal run, and that is worth doing because a one-off can be a control that has latched rather than a component that has failed.

### Where this appears, and why not to clear it

On the appliance’s own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Cut power at the breaker for thirty seconds and restore it.
- Empty the machine, fill the detergent drawer and run a normal cycle.
- If the code returns, the heater circuit or its sensing is the repair, and it should not be run in the meantime.

### Where this goes next

The job this usually becomes is [temperature sensor replacement](/services/temperature-sensor-replacement/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
