Samsung dishwasher HE error
ErrorHE
Samsung identifies HE as a heater error where temperature is detected incorrectly. Run the official empty Normal-cycle check once, then request service.
What the code means
The dishwasher is detecting temperature incorrectly
Do not remove panels or test the heater. Let the appliance cool, keep the door closed if steam or heat is abnormal, and use service if HE returns.
Typical symptoms
01HE appears during a cycle
02Heating or programme completion may be abnormal
03The code returns after an empty Normal cycle
Likely causes
Start with the least invasive explanation and stop if the check requires internal electrical or sealed-system access.
01A heater or temperature-detection fault
02A model-specific control or heating problem
Safe next steps
- 1Record HE and let the dishwasher cool if needed
- 2Empty the dishwasher
- 3Add the model-specified detergent and run one Normal cycle
- 4Stop if steam, burning smell, or abnormal heat appears
- 5If HE returns, switch off power at the circuit breaker and request service
Step-by-step repair
