What does this error code mean?
Samsung dishwasher error code HC, sometimes shown as HE, usually points to a high-temperature or heating-control problem. The dishwasher may stop during washing or drying because the temperature is outside the expected range.
Clean filters and check that the hot water supply is not excessively hot, but do not inspect heaters, thermostats, wiring, or internal sensors yourself.
HC relates to heating control, temperature sensing, circulation, and drying temperature behaviour.
Symptoms users may notice
- The dishwasher may stop during or near the end of a cycle.
- Drying may be poor or interrupted.
- The interior may seem unusually hot or steamy.
Why is this happening?
- Water temperature higher than expected
- Blocked filter affecting circulation
- Heater or temperature-sensing fault
- Control fault during heating or drying
What this usually points to
HC relates to heating control, temperature sensing, circulation, and drying temperature behaviour.
How to fix this safely
- Switch off and disconnect power before checking accessible filters.
- Clean the filter so water can circulate properly.
- Confirm the dishwasher is not being fed with unusually hot water.
- Try one normal cycle only if there is no burning smell, leak, or overheating sign.
Can I fix this myself?
MaybeYou can clean filters and check obvious supply conditions. Repeated heating or overheating warnings need diagnosis.
Safety boundary: Do not remove panels, test heaters, bypass thermostats, or run the dishwasher if it smells hot or scorched.
What not to do
- Do not keep running hot cycles if HC returns.
- Do not bypass thermostats or sensors.
- Do not remove panels to inspect heater parts.
Reset steps
- Power off for at least five minutes after safe checks.
- Restart with clean filters and normal loading.
- Stop if HC returns or the dishwasher seems unusually hot.
Intermittent vs persistent faults
A one-off HC may clear after a reset and filter clean, but repeated HC should be treated as a heating safety fault.
When to call an engineer
Call an appliance engineer if HC returns, drying or heating is abnormal, the appliance smells hot, or temperature diagnosis would require internal access.
Safety warning
Disconnect the dishwasher from power before checking filters, and do not use it if there is overheating, burning smell, damaged wiring, or any need to remove panels.
