Samsung Dishwasher HE Error Code
Wash water not reaching heat target
What this error means
HE on Samsung rotary-spray models indicates the water did not reach target temperature during wash—often the flow-through heater, thermistor, or incoming water was too cold. WaterWall models may map HE differently; check your manual.
Common causes
- Cold plumbing dead-leg—first water from tap is lukewarm
- Scale buildup in the flow-through heater passage
- Open heating element or loose wire at the terminal block
- Failed thermistor reporting low temp to the board
Step-by-step fixes
- 1Run hot water at the kitchen sink 30 seconds before starting Heavy cycle
- 2Use a dishwasher cleaner to descale the internal heater channel
- 3Retry with Heated Dry off to isolate wash heat from dry heat
- 4Avoid starting sanitize cycles when the water heater is set below 120 °F
When to call a technician
HE on consecutive cycles with hot inlet water needs heater or thermistor testing under the tub.
