Error codeOPn

Two ways to trigger OPn
Front-load washers and WashTower stacks show OPn in two situations: the cycle began while the detergent drawer was not fully inserted, or someone opened the drawer while the washer was going.
What to check
Slide the drawer in until it sits completely closed.
If your model has the ezDispense automatic dispenser, OPn means that dispenser is not shut. Push it all the way in.
Peer into the dispenser compartment and see whether anything blocks it.
OPn that lingers with the dispenser shut calls for service.
dE1 is another closed-properly code, for the drawer.
San Francisco help with LG washer repair
A drawer that is seated and still brings up OPn deserves a call to (415) 223-7887. For LG washer repair in the Bay Area, be ready to say whether your washer has the automatic dispenser, and have the model number close by.
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.
