How to Clean the Drain Pump Filter on a LG WT7300CW Washer, Step by Step Instructions
Step by step instructions for the LG WT7300CW (top load washer, direct drive). Parts and access points can differ a little by production year. The steps below cover the common layout for this platform, and the model notes flag its quirks.
You can clean a washer drain pump filter on a LG WT7300CW yourself in 15 to 30 minutes. Difficulty is easy. A pro charges a $130+ service call for a "won’t drain" visit.
- 5 steps, 15 to 30 minutes, easy difficulty.
- Tools you need are shallow pan or baking dish, towels, flashlight.
- Parts to buy are none, this is maintenance.
- Unplug the machine before you start.
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.

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.

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
