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.

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
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
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
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
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
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.

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.
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.
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.
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.
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.
