LG Washing Machine Error Code HE
Heater error — water heater circuit fault
On LG washers with an internal water heater (steam and sanitary cycles), the control detected an abnormal heating circuit — the element isn't drawing current, or the thermistor never confirmed a temperature rise. The wash continues without heated water on most models, but steam/sanitize cycles are disabled.
