Washer Won't Drain? 7 Causes and How to Fix Each One

Washer won't drain? Here are the 7 real causes — clogged pump filter, kinked hose, failed drain pump, and more — with step-by-step fixes for front-load and top-load machines.

A washer that won’t drain is the most common washing machine complaint there is — standing water in the drum after every cycle. The good news: 8 out of 10 times it’s a clog, not a broken machine. Here’s how to fix it, in order from most to least likely.

1. Clogged drain pump filter (front-load) — the #1 cause

Front-loaders have a filter behind the small door at the bottom front. It catches coins, buttons, hairpins, and lint — and when it’s full, water won’t drain. Fix: unplug the washer. Open the door, put a towel and a shallow pan underneath, and unscrew the filter cap. Let the water drain out (there will be a lot), pull out the gunk, rinse the filter, and screw it back. Run a rinse cycle to confirm.

2. Blocked coin trap (top-load)

Top-load washers have a similar trap inside the agitator or at the drain pump. Remove the agitator cap, check for debris, and clear the pump inlet. Fix: same process — unplug, find the trap, clear it.

3. Kinked or clogged drain hose

The drain hose runs from the pump to your standpipe or sink. It kinks easily if the washer is pushed back against the wall, and it can clog with lint over time. Fix: pull the machine out, straighten the hose, and check the standpipe. If the hose is old or gunked, replace it — they’re cheap.

4. The drain hose is too deep in the standpipe

If the hose is shoved too far into the standpipe, you get a siphoning/airflow problem that blocks draining. Fix: the hose end should sit a few inches inside the standpipe — not touching the water at the bottom. Check the fit.

5. Failed drain pump

If the filter is clean and the hose is clear, the pump itself may be dead. You can usually hear it — a working pump hums during drain; a dead one is silent. Fix: unplug, access the pump (bottom front panel or behind the kickplate), and test the two terminals with a multimeter. No continuity = replace the pump. It’s a common DIY job and the pump is $40–$90.

6. Blocked pump impeller

Sometimes the pump runs but the impeller is jammed with a coin or bra wire, so nothing moves. Open the pump housing and check the impeller blades — a bra underwire can stop a pump dead.

7. The error codes that mean “drain problem”

If your washer has a display, it may tell you directly: Samsung 5E/5C, LG OE, Whirlpool F21, GE drain fault. See our error-code guides for the full breakdowns:

When to call a pro

If the pump tests fine, the hoses are clear, and it still won’t drain, the problem is likely the control board or a wiring fault — that’s when a licensed tech beats a guessing game with expensive parts.

FAQ

Q: Why won’t my front-load washer drain? A: 90% of the time it’s the drain pump filter. Clean it first — it’s behind the bottom-front door.

Q: Can a clogged drain cause other washer problems? A: Yes — many washers won’t spin if water won’t drain (the spin cycle is interlocked with draining). Fix the drain and the spin often comes back with it.

Q: How much does it cost to fix a washer that won’t drain? A: DIY: $10–$100 in parts (filter, hose, or pump). Hiring a tech: $150–$350 including labor.

Always unplug the washer before opening any panel. When in doubt, call a licensed appliance tech.
