LG Washer Error Code dHE — Dry Function Heater Error
What this means
The dHE error code appears on LG washer-dryer combo units and indicates a problem with the drying heater or its temperature sensor. The heater is either not activating, overheating, or the thermistor is reading abnormal temperatures. This code only appears on models with a built-in drying function.
Alternate codes: DHE
Step-by-step fix
2 stepsPower-cycle the unit
Unplug the washer-dryer for 10 seconds, then restore power and try a drying cycle.
Clean the lint filter and ventilation
Clean the lint filter and check the ventilation path for blockages. Restricted airflow can cause the heater to overheat and trigger this code.
When to call a professional
If the error persists, the heating element or thermistor will need to be tested and likely replaced by a technician.
