LG Washer Error Code OPn

OPn on an LG washer stands for a drawer open error. It means the washer detected that the detergent drawer was not completely closed when the cycle was started, or the drawer was opened during operation. The machine stops the cycle and displays this code to prevent operating without the drawer properly seated. Closing the drawer firmly is the first step to clearing it.

The washer is designed to halt operation when OPn appears, so it will not run a cycle with the drawer detected as open. You should not attempt to force the cycle to run by bypassing the error. Once the drawer is properly closed and the error clears, the machine is safe to operate normally.

If the fix is simply cleaning the drawer or ensuring it closes properly, there is no parts cost involved. If the drawer position sensor or switch has failed and requires replacement, parts and labor costs can range from around $75 to $200 depending on the specific component and your location. If the drawer itself is damaged and needs replacement, costs are typically in a similar range depending on the model.

Start by opening the detergent drawer fully and then pushing it firmly back in until it is completely flush and seated. If the error persists, clean the drawer and the housing cavity to remove any detergent buildup that could be blocking full closure. If the drawer is fully closed and clean but the error remains, the drawer position sensor or switch may need to be inspected and tested for proper function.

A power reset alone is unlikely to permanently clear OPn if the underlying cause has not been addressed. The error will return as soon as the washer checks the drawer position again. The correct approach is to close the drawer fully and confirm it is free of obstructions, then restart the cycle. If the drawer and sensor are functioning correctly, the error will not reappear.
