Standing water in the drum after a cycle ends is one of the most common laundry calls we see across the Tri-Valley. Three things account for nearly every case: a clogged pump filter, a kinked drain hose, or a failed pump. The first two you can check in ten minutes. The third is a part swap, and it is worth getting right the first time.
This guide covers the not-draining symptom specifically. For the broader picture on washers and dryers, the washer and dryer repair guide walks through bearings, control boards, and motor couplers too.
Drain the tub first
Before anything else, get the water out so you are not diagnosing a flooded machine. Unplug it. On a front-loader, open the small access panel at the lower-right front, lay down towels, and slowly unscrew the round pump filter to let the water drain into a pan. On a top-loader, lower the drain hose end into a bucket below the water line and let gravity do it.
Check 1: the pump filter (coin trap)
The pump filter catches coins, hair pins, and lint balls. When it packs up, water cannot reach the pump impeller. This is the single most common cause of a no-drain call.
With the machine drained, fully unscrew the filter, pull it out, clear any debris, and rinse it under the tap. Reseat it firmly so it does not leak, then run a rinse-and-spin to test. If clearing it fixes the drain, you are done. If the machine still sits with water, move to the hose.
Check 2: the drain hose
The drain hose runs from the pump to the standpipe or laundry sink. Two things go wrong: it kinks when the machine gets pushed against the wall, or it clogs with lint and detergent sludge.
Pull the machine out and look at the hose. Straighten any kinks. While you are back there, check that the standpipe is not backed up either. A clogged house drain mimics a washer fault exactly, and no amount of pump work fixes a blocked standpipe.
If both the filter and the hose check out, you are past the homeowner checklist.
What a failing drain pump looks and sounds like
If those checks come back clean but water still sits in the drum, the pump is the likely cause. Listen during the drain portion of a cycle. A pump that hums or buzzes but moves no water has a jammed impeller or a worn motor. A pump that goes silent during drain has lost power, from a failed motor or a wiring fault. A burnt smell near the pump means replacement.
LG and Samsung front-loaders use the same drain pump. One quick diagnostic: turn the impeller by hand. A healthy pump resists slightly from the motor’s magnet drag. A failed pump spins loose and free with no resistance. That free-spinning impeller means the motor is done and the pump can no longer move water, even when the part looks fine. The video below shows a bad pump next to a good one side by side.
Pump replacement is a pro job. The pump seats against a housing and gasket, and if it is not seated and clamped exactly right it leaks onto the floor on the very next cycle. Doing it wrong means a second service call and a wet floor. A tech who does it every week gets it done clean and right.
Call us
If the filter and hose check out and the pump is still not moving water, or if you hear buzzing, smell burning, or see a drain error after the basics are clear, give us a call. Those point past a simple clog to the pump motor, the drain sensor, or a wiring fault. None of those are safe to guess at.

FAQ
Why is my washer not draining but spin still works? The wash motor is fine and the problem is downstream. Check the pump filter, then the drain hose, then the pump itself.
Where is the drain pump filter? On most front-loaders it sits behind a small panel at the lower-right front. Lay towels down first, since the tub can dump a gallon or more.
Should I keep running cycles to force it through? No. Running against a blockage overheats the pump and shortens its life. Drain it manually and clear the clog first.
