What OPn means

OPn is shown on LG front-load washers with an alphanumeric display, including the washer half of a WashTower and the WashCombo. It means the washer was operated without the detergent drawer fully inserted, or the drawer was opened while the washer ran. The owner sees OPn and the cycle will not continue until the drawer registers as fully closed. It is a simple position message, not a drainage or water issue.

Common causes of OPn

Detergent drawer not pushed in all the way
Drawer opened during the cycle
Drawer position not being read

✓ One safe check you can try

1. Pull the detergent drawer out and check it is seated on its rails. 2. Push the drawer in completely. 3. Restart the cycle. 4. Wipe any detergent residue from the drawer rails and opening. 5. Check that nothing is stuck behind the drawer. 6. Request service if OPn persists.

! Why to stop there

With the drawer pushed in, a returning OPn leaves the sensing that reads the drawer position in question.
We check the drawer fit and its detection, then confirm with a cycle.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

OPnOPn questions

Can opening the drawer mid-cycle cause OPn?

Yes. The washer reports OPn if the drawer is opened during operation, so close it fully and restart. The washer checks the drawer position before running, and an open or half-closed drawer stops it.

Why does OPn happen with the drawer looking closed?

It may not be pushed fully home. Press it in until it stops. If OPn remains, we look at how the washer detects it. A drawer that looks closed may sit slightly out, so press until it stops and restart.

Is OPn a leak warning?

No. It only concerns the drawer position. Wipe any detergent from around the drawer and run a cycle again. Detergent residue can also stop it seating, so wipe the drawer rails and the opening.
