LG Washer Error Code OPn — Detergent Drawer Not Fully Closed
What this means
The OPn error code appears when the washer detects the detergent dispenser drawer is open or not fully inserted. This can happen if the drawer was bumped open during operation or if residue buildup prevents the drawer from seating properly. The washer pauses until the drawer is closed.
Alternate codes: Opn
