Samsung dishwasher HE error code
HE means heater / water heat fault. The dishwasher cannot heat the water to temperature within the allowed time — the heater, its wiring or the thermistor is at fault..
Engineer usually needed · Fault type: Electrical/hardware
Safe checks, in order of likelihood
- Run the hottest program and see if the cycle completes or stops with HE.
- Power-cycle at the plug for 10 minutes to rule out an electronics glitch.
- Check the dishwasher is on its own socket — shared circuits can under-supply the heater.
Call a professional when…
The heater element, its wiring or the thermistor is tested and replaced as needed. If the code returns after these checks, book a qualified engineer.
