Samsung dishwasher HC error
ErrorHC
Samsung identifies HC as a high-temperature heater error. Follow the empty Normal-cycle check exactly once, then request service if HC returns.
What the code means
The dishwasher temperature is too high
Do not open the dishwasher while it is hot or test heater wiring. Keep clear of steam and use service if the code returns after the official check.
Typical symptoms
01HC appears during or after a cycle
02The dishwasher temperature is detected as too high
03The code returns after the official test cycle
Likely causes
Start with the least invasive explanation and stop if the check requires internal electrical or sealed-system access.
01An overheating or heater-control condition
02A model-specific temperature or control fault
