Washer Won't Drain — Why and What You Can Do

You opened the washer and there's a tub full of water. The cycle won't finish, the door won't unlock (if it's a front-loader), and the laundry is stuck inside. This is one of the most common washer problems we get called for in West Hollywood, especially in older apartments where the drain plumbing has seen better days.

Most of the time it's one of three things. You can check all three in about ten minutes.

First — drain the water out manually

Before you do anything, you need to get the water out of the drum so you don't flood the floor.

Front-loaders usually have a small drain hose behind a panel at the bottom front of the machine. There's a little plastic cap on it. Put a shallow tray on the floor (the water comes out almost level with the floor, so a baking pan works), open the cap, and let it drain. This takes a while — there can be five or more gallons in there.

Top-loaders don't usually have an external drain hose. You'll need to bail the water out with a pitcher or use a wet/dry vacuum.

1. Check the drain pump filter

Front-load washers have a filter (sometimes called a "trap" or "pump cleanout") that catches coins, hair clips, kids' toys, and other small things before they reach the drain pump. When it's clogged, water can't drain.

It's behind the same panel as the drain hose. Once the water is out, unscrew the filter (it's a big knob, you turn it counterclockwise — be ready for a little more water and probably some lint and a missing sock or two).

Clean it out, screw it back in tight, and try a rinse cycle. About 40% of "not draining" calls are this simple. We've pulled out everything from coins to a metal hair clip to a hotel room key card.

Top-loaders usually don't have a user-accessible filter — for those, the issue is more likely number 2 or 3 below.

2. Check the drain hose for kinks or clogs

The drain hose runs from the back of the washer up into the standpipe in the wall. In an older West Hollywood apartment, that standpipe might have been narrow to start with and is now half-full of lint and gunk after a few decades.

Pull the washer out from the wall (carefully — don't strain the water lines). Look at the drain hose. If it's kinked, straighten it. If you can pull it out of the standpipe, do that and run a cycle into a bucket on the floor. If the washer drains fine into the bucket, your standpipe in the wall is clogged. That's a plumber, not me.

If it doesn't drain into the bucket either, the hose itself or something inside the washer is the problem.

3. Listen to the drain pump

Run a drain or spin cycle and put your ear close to the bottom of the washer. You should hear the drain pump running — a steady humming or whirring noise.

• If you hear nothing — the pump motor or its wiring is dead. The pump itself needs replacement, usually $220–$320 parts and labor.
• If you hear a humming or grinding but no water moves — the pump is jammed. Sometimes this is a small object stuck in the impeller. Replacement is the usual fix.
• If you hear the pump running normally but water still won't drain — go back to checking the hose and standpipe.

What if it's not any of those?

Less common but possible:

• Lid switch (top-loaders) — if the washer thinks the lid is open, it won't drain or spin. Quick fix.
• Door lock (front-loaders) — same idea. The cycle won't proceed without the door fully locked.
• Control board — uncommon, but if the diagnostic shows no fault and the pump is fine, sometimes the main control board has failed.

What it usually costs

Most "won't drain" repairs run $180–$350 parts and labor. The main exception is a control board, which can push $400–$550 on certain LG and Samsung front-loaders. We'll tell you the part cost in writing before any work starts.
