LG Washer Error Code 13C

The 13C code on an LG washer signals a washing motor error and hall sensor fault in the upper washer unit. It is the upper-drum equivalent of the 3C error code. The fault means the control board cannot properly drive the upper motor or receive valid feedback from the motor's hall sensor. The washer stops the cycle automatically to prevent damage.

No, you should not continue running the washer while the 13C code is active. The upper drum motor is not operating correctly, and forcing the machine through cycles could worsen the fault or cause additional damage to the motor, wiring, or control board. Leave the washer unplugged until the issue is diagnosed and repaired.

Repair costs vary depending on the failed component. If the fix is simply reseating a loose connector, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing a hall sensor or motor winding repair can add parts costs of roughly $50 to $150, while a full motor replacement or control board swap can bring total costs into the $200 to $450 range including labor.

The first diagnostic step, checking the motor connector terminals and contacts, is something a capable DIYer can attempt by unplugging the machine and inspecting the harness connection at the motor. If the connector looks secure and clean but the error returns, further diagnosis involving wiring continuity checks, hall sensor testing, and motor winding resistance measurements is typically better handled by a qualified technician.

A power reset may temporarily clear the display, but the 13C code will return as soon as the washer attempts to run the upper motor and the underlying fault is still present. Resetting alone does not fix connector problems, sensor failures, or motor faults. A proper repair addressing the root cause is needed to eliminate the error permanently.
