LG Washer Error Code 1HC

The 1HC code on an LG washer indicates a heater error in the upper washer unit. It is triggered when the washing heater is detected as short-circuited or when the wire connection to the heater has been lost. The washer stops operation when this code appears to prevent further electrical or mechanical damage.

No, you should not continue using the washer while the 1HC code is displayed. A short-circuited heater or damaged wiring can pose an electrical hazard, and the washer will typically not complete its cycle anyway. Unplug the appliance and diagnose the fault before attempting to run another load.

Repair costs depend on the specific fault found. If only a loose connector needs to be reseated, there may be little to no parts cost. Replacing a failed heater element typically runs anywhere from $30 to $100 or more for the part, plus labor if a technician is hired. A full service call with diagnosis and repair can range from $100 to $300 or higher depending on your location and the parts required.

Some causes of the 1HC error are accessible to a knowledgeable DIYer. Start by unplugging the washer and checking the wire harness connection at the heater for looseness or corrosion. If the connector is secure and undamaged, testing the heater element for proper resistance and inspecting the harness for damage are the next steps, though component replacement may require comfort working with appliance wiring.

Resetting the washer by unplugging it for a few minutes may temporarily clear the code, but it will return if the underlying wiring or heater fault has not been corrected. A reset alone does not repair a disconnected wire or a failed heater element, so the root cause must be addressed for the error to stay cleared.
