LG Washer Error Code HC2

HC2 on an LG washer indicates a drying system overheating fault. It is triggered when the water level sensor detects no water while the temperature sensor reads between 100°C and 150°C, or when the drying heater has a short circuit, a disconnected wire, or a heater engagement failure. In response, the washing machine cuts input power as a safety measure. The heater circuit and wiring should be inspected before attempting to restart the machine.

No, you should not continue using the washer until the HC2 fault has been diagnosed and resolved. The error indicates a potentially dangerous overheating condition or a heater circuit fault, both of which carry a risk of further component damage or, in severe cases, a fire hazard. The machine shuts off input power as a protective response, and operating it again before repair could cause additional harm.

A reset may temporarily clear the HC2 code from the display, but it will not resolve the underlying fault. If the heater is shorted, a wire is disconnected, or the temperature sensor continues to detect an overheating condition, the code will return as soon as the machine attempts to run the drying cycle again. The root cause must be identified and corrected before the error will stay cleared.

Some causes of the HC2 error, such as a loose or disconnected wire at the heater, can be addressed by a knowledgeable DIYer comfortable working with appliance wiring. However, diagnosing a shorted heater element, testing heater engagement components, or replacing a faulty control board relay typically requires a multimeter and some technical experience. If you are not comfortable working around high-voltage components, it is best to contact a qualified repair technician.

Repair costs depend on the root cause. If only a wire connection needs to be reseated or tightened, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing a defective heater element generally costs between $100 and $250 including parts and labor. Control board replacement, if required due to a relay or engagement fault, can range from $200 to $400 or more depending on parts availability and technician rates.
