LG Washer OE: A Drain Warning Is Not a Pump Diagnosis

OE

LG front-load guidance

A drainage warning

OE identifies a drain concern, not a verified pump failure. Match the full display and model before applying this reference.

Record the water state and the exact display

Note whether water remains, whether the warning returned and whether an accessible drain hose is visibly bent. Keep a display photograph. A pump sound alone doesn’t complete the diagnosis.

Filter access and controlled water release need the exact owner procedure. Don’t open an unidentified filter to investigate retained water.

Choose the next task from what you observe

Water remains in the drum
Keep that state with your service notes and follow the drainage observations.
Continue with drainage checks
The tub looks empty, but OE returned
Record both facts. Don’t replace them with a guessed failed sensor or pump; request the applicable next check.

Could the character be zero? Compare the display photograph and the matching manual before using this OE reference.

The code doesn’t supply a part number

If drainage doesn’t return, ask which documented finding establishes the fault before ordering a pump or sensor. This is interpretation and safe routing, not a full repair procedure or a verified part match.
