LG Washer Error Code 19C2

The 19C2 code on an LG washer indicates a power error affecting the upper washer unit. It signals that the upper unit is not receiving proper power, which is most often traced to the plug receptacle connection between the upper and lower units. Voltage levels at the receptacle and the physical condition of the connection should be inspected first.

When the 19C2 error is active, the upper washer unit is not functioning correctly due to a power fault. Continuing to use the appliance without addressing the issue is not recommended, as an underlying wiring or connection problem could pose an electrical risk. It is best to stop using the upper unit and diagnose the power issue before running additional cycles.

Repair costs vary depending on the cause. If the fix is simply reseating the plug receptacle, there is no parts cost involved. Replacement wiring harnesses or receptacle components can range from around $20 to $80 in parts. A control board replacement is the most expensive possibility, with parts typically ranging from $100 to $300 or more, plus labor if a technician is involved.

Start by confirming that the plug receptacle connecting the upper washer is fully and securely plugged in. Next, use a multimeter to verify that the voltage at the receptacle is correct. If the connection and voltage are both good, inspect the wiring harness and terminals for damage or corrosion. If internal components like the harness or control board are faulty, those parts will need to be repaired or replaced.

A basic reset may temporarily clear the error code display, but if the underlying power issue is not resolved, the 19C2 code will return once the machine attempts to operate the upper washer again. Resetting should only be used after the root cause, such as a loose receptacle or incorrect voltage, has been identified and corrected.
