Error codeOPn
ApplianceWasher
Quick answer
OPn appears when the detergent drawer is not fully inserted or is opened while the washer runs.
Model compatibility: LG reuses codes across series and model years, so OPn may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The detergent drawer was not fully inserted, or was opened during operation.
OPn means the washer ran without the detergent drawer fully inserted, or the drawer was opened while the washer was running. It applies to front-load washers and WashTower units.
What to do
Push the drawer in until it is completely seated.
On models with the ezDispense automatic dispenser, the code appears when the dispenser is not fully closed. Close it by pushing it in all the way.
Look into the dispenser compartment for anything in the way.
If OPn stays even with the dispenser fully closed, request service.
A drawer that is seated yet still triggers OPn is worth a call to (310) 742-8008. Our LG washer repair team in Los Angeles will ask for the model number and whether yours has the automatic dispenser.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
