Samsung Washer HE2 Error Code: Causes and Fixes
Quick answer: On a Samsung Washer, the HE2 error code means a fault has been detected in the heater relay circuit or the heater is overheating. Samsung Washer HE2 is a heater-related fault that is specifically associated with the heater relay on the control board or a temperature reading that has gone above the expected maximum. HE2 can indicate that the thermostat has failed to cut out at the correct temperature, or that the relay that controls the heater is stuck on.
Quick Fix for Samsung Washer HE2
- Run a power reset: unplug the washer for 5 minutes.
- Allow the machine to cool down completely before reconnecting.
- Select a cold wash to test basic machine operation.
- If HE2 only appears on hot wash programs, the heater circuit or its relay needs to be inspected.
- For persistent HE2, a qualified technician should inspect the heater relay and control board.
Common Causes of Samsung Washer HE2
- Heater relay fault: The relay on the control board that switches the heating element on/off is stuck closed (on), causing overheating.
- Overtemperature condition: The water temperature has exceeded the safe maximum, triggering a thermal cutout.
- Failed thermostat: The safety thermostat that should cut out the heater at maximum temperature has failed.
- Thermistor fault: An incorrect temperature reading from the thermistor causes the control board to apply heat beyond the correct temperature.
- Scale buildup: Thick limescale insulation on the heater element causes hot spots and overtemperature.
