How to Clean the Drain Pump Filter on a LG WT7405CV Washer — Step-by-Step Instructions
Step-by-step instructions for the LG WT7405CV (top-load washer, direct drive, 4.8 cu ft). Parts and access points can differ slightly by production year — the steps below cover the common layout for this platform, and the model notes flag its quirks.
Unplug the washer first. The trap may hold a surprising amount of water — go slow with the cap and let it drain into the pan in stages.
Tools
- Shallow pan or baking dish
- Towels
- Flashlight
Parts
- None — this is maintenance
Step by step
-
1 Find the access door
On nearly every front-loader there’s a small rectangular door or kick-panel at the bottom front corner. Pop it open with a flat screwdriver or coin.
-
2 Drain the water first
Most machines hide a small rubber drain hose next to the filter cap. Pull it out, aim it into your shallow pan, and remove its plug. No hose? Unscrew the filter cap a quarter-turn and let water seep out in stages.
-
3 Unscrew the filter
Turn the cap counterclockwise and pull the coin trap straight out. Expect gunk: lint mats, coins, hair pins, guitar picks, and at least one sock over the machine’s lifetime.
-
4 Clean everything
Rinse the filter under hot water, scrub with an old toothbrush, and shine a flashlight into the pump housing — spin the impeller with a finger to make sure nothing is jammed behind it.
-
5 Reinstall and test
Screw the filter back in snugly (crooked threads leak), replug the drain hose, close the door, and run a short cycle to confirm draining and no drips.
LG WT7405CV notes & error codes
Worn suspension rods are the defining complaint on LG top-loaders and they wear as a set. Replacing one or two leaves the remaining tired rods to fail within months, and the customer reads that as a repair that did not work.
| Code | What it means |
|---|---|
| OE | Drain error |
| LE | Motor locked / rotor position fault |
| UE | Unbalanced load |
| IE | Inlet / fill fault |
| dE | Lid lock fault |

If the filter is clean but the washer still won’t drain — or the pump hums or grinds with the filter out — the pump itself is likely failing, and diagnosing pumps vs control faults is quick work for a tech. If you'd rather skip it entirely, find a washer repair pro near you →
