LG Washer Error Code 19C1

The 19C1 code on an LG washer indicates a power error affecting the upper washer unit in a twin-load configuration. The machine has detected that the voltage supplied to the upper unit's internal power terminals is outside the acceptable operating range. This can stem from problems with your home's electrical supply or from an internal component issue such as a faulty control board or damaged wiring.

Yes, power-related errors should be taken seriously. Abnormal voltage conditions can potentially damage internal components over time or indicate a wiring fault that poses a risk. Avoid continued use of the upper washer unit until the source of the power error has been identified and corrected.

Repair costs vary depending on the root cause. If the issue is simply a circuit or outlet problem, the cost may be minimal, ranging from nothing to a modest electrician service call fee. If an internal component such as the power control board requires replacement, parts and labor combined could range from around $150 to $400 or more depending on your location and service provider.

Start by measuring the voltage at the wall outlet to confirm it meets the washer's requirements, and make sure the appliance is on an adequate dedicated circuit. If household power checks out, inspect the internal power terminals and wiring harness connectors for looseness, corrosion, or damage. If those connections appear sound, the power control board may need to be tested and potentially replaced by a qualified technician.

A reset may temporarily clear the code, but if the underlying power issue is not resolved, the error will return. To reset, unplug the washer for a few minutes and then restore power. If the code reappears immediately or after the next wash cycle, a deeper diagnostic of the power supply and internal components is necessary.
