LG Error Code HE
Heater error
Common Causes
- 1Heating element failure
- 2Thermostat issue
Step-by-Step Troubleshooting
- 1
Check if the dishwasher is connected to the hot water supply — LG dishwashers require incoming water temperature of at least 120F (49C) for optimal performance
- 2
Run the hot water at the kitchen faucet until it is hot before starting the dishwasher — this ensures hot water reaches the unit immediately
- 3
Access the heating element at the bottom of the tub — test for continuity with a multimeter; a functioning element reads 15-30 ohms
- 4
Inspect the element for visible cracks, warping, or mineral scale buildup that can create hot spots and eventual burnout
- 5
Check the thermistor sensor near the heating element — if it reads incorrectly, the board may not activate the heater relay
Pro Diagnostic Tip
LG dishwashers use the heater for both wash temperature boost and dry cycle. If dishes wash clean but come out wet, the heater works during wash but the dry-cycle relay on the board may be failing independently. Test the heater relay separately.
