Washing Machine Won't Drain — Causes and How to Fix It
Standing water in the drum at the end of a cycle is one of the most common washer problems — and one of the most fixable at home. The vast majority of drain failures come down to three things: a clogged pump filter, a blocked or kinked drain hose, or a failed drain pump. Work through them in that order before calling anyone.
1. Clean the Drain Pump Filter First
On front-load washers (and many top-loaders), there is a small access panel at the front-bottom of the machine. Behind it is the drain pump filter — a screw-out trap that catches coins, lint, hair ties, and socks. This is the number-one cause of a no-drain. Unplug the washer, lay down towels and a shallow tray (a lot of water will come out), and slowly unscrew the filter to drain it. Clean out everything, check the impeller behind it for debris, and reinstall. Many washers drain perfectly the moment this trap is cleared.
2. Check the Drain Hose
The corrugated drain hose runs from the back of the washer to a standpipe or under-sink connection. Pull the washer out and inspect the hose for kinks, and disconnect it to check for clogs — lint and debris collect where the hose meets the standpipe. Make sure the hose is not pushed too far down the standpipe, which can cause siphoning. Clear any blockage and confirm the standpipe itself drains freely.
3. Test the Drain Pump
If the filter and hose are clear and the washer still won't drain, the drain pump itself may have failed. Listen during the drain step: a pump that hums but moves no water, or is completely silent, is likely bad. With the washer unplugged, you can access the pump (usually behind the front or rear panel), check it for continuity with a multimeter, and inspect the impeller. A replacement pump is an affordable, common DIY repair on most brands.
4. Rule Out a Suds Lock
Too much detergent — or standard detergent in an HE machine — creates excess suds that the pump cannot move. Many washers will flash a suds code (Sud, Sd, 5d) and pause. If you over-dosed detergent, run an extra rinse cycle and switch to a small amount of HE detergent going forward.

FAQ
The washer could not pump the water out in time. Start with the drain pump filter (front-bottom access panel) — a clog there is the most common cause — then check the drain hose, then the pump itself.
Yes. Unplug it, then either lower the drain hose into a bucket below the drum level to gravity-drain, or slowly open the drain pump filter with towels and a tray ready to catch the water.
Replacement drain pumps typically run $30 to $80 for the part, and it's a common DIY repair on most washers with basic tools.
