What OPn (Detergent Drawer Not Inserted) Means
OPn appears when the washer was operated without the detergent/softener drawer fully inserted, or the drawer was opened while the washer was running, per LG's front-load washer Help Library article.
Common Causes of OPn (Detergent Drawer Not Inserted)
- Detergent drawer not fully inserted before starting
- Drawer opened accidentally mid-cycle
🔧 One Safe Check You Can Try
Make sure the detergent drawer is pushed in completely until it seats flush with the washer's front panel, then restart the cycle.
⚠ Why You Shouldn't Go Further Than That
- There's no repair here beyond seating the drawer correctly - if it still won't fully insert or seems to slide loosely even when apparently closed, the drawer's guide rails or latch may need a technician's look.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
