A washer that stops mid-cycle with a tub full of gray water needs two things: the water out without flooding the floor, and an answer to where the blockage is. Water leaving a washer passes through three places: the machine's own pump, the drain hose, and your home's drain. A stoppage in any one of them looks the same from the front of the machine, so the job is to check them in order.
First, make it safe
Unplug the washer, or switch off its breaker if the plug is hard to reach. You'll be working near water and near the pump, and you don't want the machine to start draining or spinning while your hands are inside it. Closing the hot and cold supply valves behind the washer is a good habit too, so a stuck inlet valve can't keep adding water.
If the laundry room is upstairs, which is the case in a lot of two-story homes built around Charlotte since the 1990s, take extra care. A few gallons on the floor upstairs can soak through to the ceiling below. Lay down towels before you open anything, and work slowly.
Get the water out
Front-loaders. Most have a small access door low on the front panel. Behind it is the drain pump filter, and many models also have a short drain tube next to it. Put down towels and a baking pan or other shallow tray, pull the tube out, uncap it and let the tub drain into the pan, emptying it as often as needed. There may be more water than you expect. Once the flow stops, turn the filter cap counterclockwise slowly and let the rest out before removing it fully.
Top-loaders. Lift out the clothes, wring them over the tub, and bail the water with a small container into a bucket. Many top-loaders have no user-serviceable filter; the pump sits behind the cabinet or underneath, which is why a top-load drain problem more often needs a technician.
Check the machine: filter and pump
With the front-loader drained, look in the filter housing. Socks, hair ties, coins, bra wires, tissue and lint all end up there. Clean the filter under the tap, wipe the housing, and reinstall it firmly. A loose filter cap leaks on the next cycle.
While the filter is out, shine a flashlight into the opening. You may see the pump impeller, a small plastic wheel. With the washer still unplugged, check whether something is wedged against it. If you can turn it gently with a finger and it moves freely, that's a good sign.
Now plug the washer back in and run a drain-and-spin cycle with no clothes. Listen:
- A steady hum but no water moving usually means the pump is jammed or the impeller has failed.
- No sound at all from the pump points to the pump motor, its wiring, or the control that powers it.
- Normal drain sound, but the washer still errors out can be a hose or house-drain problem, or a pressure sensing fault.
Check the hose
Pull the washer out and look at the drain hose. Washers get pushed back against the wall after a move or a cleaning, and a hose that folds behind the cabinet can pinch nearly shut. Straighten it, and make sure it isn't crushed or kinked where it rises to the standpipe or laundry sink.
How the hose goes into the drain matters too. The installation instructions list a maximum height for the drain and how far the hose should go into the standpipe. A hose pushed too deep, or sealed tight with tape, can siphon water or trap air; a drain mounted higher than the pump can push against makes the pump struggle.
Check the house drain
Run a bucket of water down the standpipe or laundry sink. If it backs up or drains slowly, the clog is in the plumbing, not the washer. Lint and detergent sludge build up in laundry drain lines over the years. That's a job for a plumber or a drain snake, not an appliance repair visit.
Don't pour chemical drain cleaner into the washer itself. It can damage the pump seals and hoses, and it won't reach a clog in the house line from inside the tub anyway.
Garage laundry and winter freezes
If your washer sits in an unheated garage, a hard freeze can leave ice in the pump, the drain hose or the inlet hoses. The washer then fills, can't drain, and shows a drain error, with nothing actually broken. Let the space warm up and give the water time to thaw before running a cycle. Don't pour boiling water into the machine or onto the hoses. Once it drains normally, check the floor for drips, since a frozen hose can split.
Apartments and stacked units
In Uptown and South End apartments, the washer is often a stacked or compact unit in a closet. Before you pull it out, check with building management; some buildings handle in-unit appliances themselves, and stacked units are heavy and awkward to move. The filter on a compact front-loader is usually still reachable at the front.
When it's time for a technician
Book a repair visit if:
- The pump hums but won't move water after the filter is clean.
- The pump is silent.
- The drain error comes back after you've checked the filter, hose and house drain.
- Water drains but the washer won't spin, or it won't unlock the door or lid at the end of the cycle.
A technician comes to the house, tests the pump, wiring, lid switch or door lock, and controls, explains what failed, and quotes the repair before any work starts. Parts are matched to your model number. See our washer repair service for what we handle. LG owners can also read our guide to LG washer problems, which covers the drain error on those machines. If clothes are coming out of the dryer damp instead, our dryer not heating guide is the better place to start.
Frequently asked questions
Why do my clothes come out soaking wet even though the washer drained?
The washer may be draining but not reaching full spin speed. A partly blocked pump or filter can slow draining enough that the washer cuts the spin short. An unbalanced load, a worn drive part or a faulty lid switch or door lock can also stop the spin. Start with the filter, then have it diagnosed.
How often should I clean the drain pump filter?
Follow your owner's manual; most makers suggest checking it every few months, and right away whenever a drain error appears. Homes with pets or lots of small items in the wash may need to clean it more often.
Can I run another load to see if it clears itself?
Better not. If the washer can't drain, another fill adds more water to a machine that can't get rid of it, which raises the chance of an overflow. Find the blockage first.
Is a washer that won't drain worth fixing?
Usually. Drain pumps, filters, hoses and lid switches are among the more straightforward washer repairs. If the washer is old and has other problems too, such as bearing noise or leaks, we'll tell you whether the repair still makes sense.
