My washer won't drain — what do I do?

A washer that fills and washes but leaves standing water almost always comes down to one thing between the tub and your drain being blocked, or the pump quitting. It's one of the most common — and most affordable — repairs we do. Below are the real causes in the exact order we check them, the tests a technician actually runs (including the multimeter readings), the parts and honest price ranges, and the safe checks you can do yourself first.

⚠ Safety first: Always unplug the washer before touching the pump or hoses, and keep towels + a shallow pan ready — there will be trapped water. Only test electrical parts with the machine unplugged.

How a washer's drain system works (30 seconds)

When the wash is done, the control tells the drain pump to run. Water leaves the tub, passes a filter/coin trap (front-loaders and most HE top-loaders), and goes out the drain hose to your standpipe or disposal. Most machines also won't drain or spin unless the lid switch / door lock tells the control the door is secure. So a no-drain is almost always: a blockage in that path, a dead pump, or the control never getting the 'door closed' signal.
What we see most: on standard top-loaders it's usually the drain pump or a jammed impeller; on front-loaders and HE machines, the clogged filter/coin trap is the #1 cause by a mile — and it's a 10-minute DIY. Start there before buying anything.

The most likely causes — in the order we check them

Clogged pump filter / coin trap Easy DIY check

Front-loaders and many HE top-loaders have a filter that catches coins, hair pins, and lint. When it packs solid, water can't leave the tub. Single most common cause.

Test it yourself: Unplug the washer. Find the small access panel at the bottom-front, put a shallow pan + towels down, and slowly unscrew the filter cap to drain it. Pull the filter and clear everything — you'll often find coins, hair, even a sock. Spin the little impeller behind it with a finger; it should turn freely.

🔩 Likely part: usually no part — just cleaning — $0

Tools: Shallow pan + towels, Maybe pliersTime: 10–20 min

Kinked or clogged drain hose Easy DIY check

The hose to your standpipe or disposal can kink behind the machine or clog with lint/gunk where it connects. If it's pushed too far down the standpipe it can also siphon.

Test it yourself: Pull the washer out and look at the hose end-to-end for kinks or crush points. Disconnect it (bucket ready) and check for a clog; run water through it. Make sure it enters the standpipe no more than ~6 inches.

🔩 Likely part: drain hose (only if split/clogged solid) — $15–35

Tools: Bucket, Pliers/hose clampTime: 15–30 min

Object stuck in the pump impeller Moderate DIY

A sock, underwire, or coin gets past the filter and jams the impeller so the pump can't move water — often with a hum.

Test it yourself: With the machine unplugged and the filter removed, reach in and feel the impeller. If it won't spin freely or you feel a hard object, remove it. If the impeller vanes are broken off, the pump needs replacing.

🔩 Likely part: drain pump (only if impeller is damaged) — $30–70

Tools: Flashlight, TowelsTime: 20–40 min

Failed drain pump Technician

The drain pump is a small motor that pushes water out. When the motor windings burn out or the bearings seize, you get a hum with no water movement, or silence.

How a tech tests it: With the machine unplugged, put a multimeter on the pump motor terminals: a good winding reads a few to ~20 ohms. An open reading (OL / infinite) means the motor is dead — replace the pump. (A pump that hums but won't move water with a clear impeller is also done.)

🔩 Likely part: drain pump — $30–70

Tools: Multimeter, Nut driver / screwdriversTime: 45–90 min (tech)

Lid switch or door lock Technician

Most washers won't advance to drain/spin unless the control sees the lid or door as securely closed. A failed switch makes the machine act 'stuck' even though the pump is fine.

How a tech tests it: With power off, test the switch/lock for continuity: it should read continuity (near 0 ohms) when latched and open when released. No change when you latch it = failed switch.

🔩 Likely part: lid switch / door lock — $20–60

Tools: Multimeter, ScrewdriversTime: 30–60 min (tech)

Tools you'll need for the DIY checks

Repair or replace? (the honest math)

A filter clog, hose, or drain pump is an inexpensive fix — parts are typically $0–$70 — and it's worth repairing on a washer of almost any age. Replacement only enters the conversation when a drain failure is paired with another big-ticket failure (worn tub bearings and a dead control board, say). We'll give you the honest math before you spend anything.

Common questions

Why is there standing water in my washer?

The drain step failed. Usual causes: a clogged pump filter/coin trap, a kinked or clogged drain hose, a jammed impeller, or a worn-out drain pump. Unplug the machine and check the filter at the bottom-front first — it's the most common.

How do I know if my washer drain pump is bad?

Two signs: it hums during drain but no water moves (with a clear impeller), or it reads open (OL) on a multimeter across the motor terminals. A good pump winding reads roughly a few to ~20 ohms.

Can I fix a washer that won’t drain myself?

Often yes — clearing the filter/coin trap, checking the hose for kinks, and freeing a jammed impeller are all safe with the machine unplugged. A failed pump or lid switch is a quick technician repair.

What does the filter/coin trap look like?

A round, screw-in cap behind a small panel at the bottom-front of most front-loaders and HE top-loaders. Open it slowly over a pan — there's always some water behind it.

Is a washer that won’t drain worth fixing?

Almost always. The common causes are cheap parts on any age of washer. Send us a 10-second video and we'll tell you the exact part and whether it's worth it — honestly.
