LG Washer Error Code 6C

The 6C code on an LG washer signals a power supply error caused by under-voltage, over-voltage, or unstable electrical conditions at the machine's outlet. It can also indicate a fault in the main control board (PBA) if the power supply itself is confirmed to be within normal range. The washer shuts down to protect its internal components when this condition is detected.

Unplugging the washer for a few minutes and restarting it may temporarily clear the 6C code, but it will return if the underlying power issue has not been resolved. A reset does not fix a faulty outlet, unstable supply voltage, or a defective control board. Confirm that the root cause is corrected before relying on a reset.

Costs vary depending on the root cause. Replacing a faulty wall receptacle typically runs between $75 and $200 including labor. If the main PBA is at fault, control board replacement can range from $150 to $400 or more depending on parts and labor rates in your area. Many 6C errors are resolved by correcting the power supply without purchasing any parts at all.

Start by checking the wall outlet and home circuit for stable, correct voltage. Make sure the washer is plugged directly into a dedicated outlet and not into an extension cord or a circuit shared with other high-draw appliances. If the power supply is confirmed good, inspect wiring connections in the power path. If the error persists, the main PBA may need to be tested and possibly replaced by a qualified technician.

You should not continue running the washer while this error is active. The code indicates the machine is receiving abnormal voltage, and operating under those conditions could damage internal components or create an electrical hazard. Resolve the power supply issue before running another cycle.
