Quick answer
A washer that won't drain is most often blocked by a clogged drain-pump filter, a kinked drain hose or a jammed drain pump. On a front-loader, clean the small filter behind the access door at the bottom front first. If the filter is clear and the pump hums or stays silent, the pump itself has likely failed.
Opening the washer to a drum full of gray water is one of the most common laundry calls we get. The good news is that most drain problems are a blockage, not a broken machine, and many can be cleared without a service call.
Work through the causes below in order. They start with the free checks and move toward parts that need a technician. Have towels and a shallow pan ready before you open anything, because a full front-loader can hold several gallons below the door line.
Causes, from most to least likely
1.Clogged drain-pump filter
Most front-loaders, and some top-loaders, have a coin trap in front of the drain pump. It catches socks, hair ties, coins, bobby pins and lint. Once it packs up, water can't reach the pump and the washer stops with a drain error, such as 5C or nd on Samsung or OE on LG.
- Check it yourself
- Unplug the washer. Open the small door at the lower front, set out towels, and unscrew the filter slowly counterclockwise. Pull out anything caught in it, rinse it and screw it back in snugly so it doesn't leak.
- The fix
- Cleaning the filter is free. If it's cracked or the threads are stripped, the filter or housing is replaced. Cleaning it every month or two prevents most repeat clogs.
2.Kinked drain hose or a clogged house drain
The corrugated drain hose behind the washer kinks easily when the machine is pushed back against the wall. The standpipe or laundry sink it empties into can also clog, so the washer pumps fine but the water has nowhere to go.
- Check it yourself
- Pull the washer out a few inches and look for flat spots in the hose. Pour a bucket of water into the standpipe. If it backs up, the clog is in your plumbing, not the washer. The hose should go only about 6 to 8 inches into the standpipe, not all the way down.
- The fix
- Straighten or replace the hose. A clogged standpipe or house drain is a plumber's job.
3.Failed or jammed drain pump
The drain pump is a small motor with a plastic impeller. Something that slips past the filter can lock the impeller, and the pump motor eventually burns out. A pump that hums with no water moving is usually jammed. One that makes no sound at all may have an open winding or no power from the control.
- Check it yourself
- Start a drain-and-spin cycle and listen near the lower front. A hum or buzz with no water flow points to a jam. Rattling or grinding means debris in the impeller.
- The fix · typical $170 – $290
- We remove the pump, clear the impeller and test the motor. If the winding is open or the impeller is broken, the pump is replaced. On most models it's about an hour of work.
4.Sand and grit in the sump
Beach towels, swimsuits and kids' clothes from Clearwater Beach carry more sand than most people expect. It settles in the sump at the bottom of the tub, packs the filter, and wears the pump impeller over time. Vacation rentals that wash beach towels every day see this a lot.
- Check it yourself
- When you clean the filter, look for a gritty layer in the housing. Shake beach towels out well and rinse sandy items with a hose before they go in the washer.
- The fix · typical $170 – $290
- A light buildup flushes out with the filter. Heavy packing means pulling the pump and flushing the sump hose. If the impeller is worn, the pump is replaced.
5.Too many suds
Regular detergent in a high-efficiency washer, or simply too much HE detergent, creates foam. Pumps move water, not foam, so the washer can sit full of suds and throw a drain or suds error. Samsung shows Sud for this.
- Check it yourself
- If the drum is full of foam, run a rinse-and-spin with no detergent, then repeat. Use HE detergent and measure it. Most loads need far less than the cap line.
- The fix
- No part needed. If it keeps happening with correct detergent, we check the pressure sensor and the pump.
6.Lid switch or door lock not confirming
Many washers won't drain and spin until the control confirms the lid or door is locked. A worn lid switch on a top-loader, or a failing lock assembly on a front-loader, can stall the cycle with water still in the tub.
- Check it yourself
- Watch for a lock light or a click when the cycle starts. If the lock light flickers or the washer fills and washes but stops before spin, the lock is a strong suspect.
- The fix · typical $160 – $280
- The lid switch or door lock assembly is replaced and tested through a full drain and spin.
7.Control board not powering the pump
Least likely, but it happens. The main control sends voltage to the drain pump. A failed relay, or a pressure sensor feeding it a bad water-level reading, can mean the pump is never told to run.
- Check it yourself
- This one needs a meter. If the filter, hose and pump are all fine and there's still no drain, electrical testing is the next step.
- The fix · typical $280 – $520
- We confirm voltage at the pump during a drain command before condemning the board. Only then do we quote a board replacement.

What the warranty covers →Common questions
How do I drain a washer that's full of water?
+
Unplug it first. On most front-loaders, open the small access door at the bottom front. Many models have a short bypass hose next to the filter that you can uncap over a pan. Drain it in stages, then remove the filter. On a top-loader, bail the water out with a bucket or lower the drain hose into a bucket below the level of the tub.
How often should I clean the washer drain filter?
+
Every month or two for most households. If you wash a lot of beach towels, pet bedding or kids' clothes, check it more often.
Can I just replace the drain pump myself?
+
On some front-loaders it's a reasonable DIY job if you're comfortable unplugging, draining and removing a few screws and hose clamps. Make sure the pump is actually the problem first. A jammed impeller often just needs to be cleared.
Why does my washer drain but leave clothes soaking wet?
+
That's usually a spin problem, not a drain problem. Our washer-not-spinning guide covers it. An unbalanced load, a worn belt or coupler, or a door lock fault are the common causes.
Is a drain pump repair worth it?
+
Nearly every time. It's one of the less expensive washer repairs, and a new pump fixes the problem completely. It's rarely the reason to replace a washer.
