What the appliance detected
Detected condition
Samsung says HE means the temperature inside the dishwasher is being detected incorrectly.
What may contribute
Possible causes
- The temperature inside the dishwasher is being detected incorrectly.
- A temporary cycle condition may clear after an empty Normal cycle with detergent.
- A temperature sensor, heater, wiring, or control issue may require service if the code returns.
Start conservatively
Safe preliminary checks
Work in order and stop whenever a step is not supported by the documentation for your model.
Record the code and stop for hazards
- Photograph or write down HE before clearing the display.
- Stop for smoke, burning odor, sparking, abnormal heat, visible damage, or water near electrical parts.
Run only the documented empty-cycle check
- Empty the dishwasher.
- Add detergent and run a Normal cycle if there are no hazard signs and the owner manual supports normal use.
Preserve a returning code
- If HE still occurs, switch off power to the dishwasher at the circuit breaker and request Samsung service.
- Do not continue running cycles or repeatedly resetting the dishwasher.
Actions not recommended
- Do not access the heater, sensor, wiring, control board, or internal electrical parts.
- Do not test live voltage or replace temperature parts based on HE alone.
- Do not run cycles if overheating, smoke, burning odor, sparking, or leakage is present.
When to stop and request service
- Request Samsung service if HE returns after the documented empty Normal cycle.
- Stop immediately for abnormal heat, smoke, burning odor, sparking, visible damage, or water near electrical parts.
- Use qualified service for any internal temperature, heater, wiring, or control diagnosis.
