Washing Machine Not Draining? Here's What to Check First

A tub full of standing water is one of the top calls we get. Walk through these four checkpoints in order and you'll likely find the cause before a technician ever needs to.

Quick Answer

A washer that won't drain is almost always the drain hose, the pump filter, or the drain pump motor — check them in that order. Front-load owners should look at the pump filter first; it causes more no-drain calls than anything else on the machine.

Few things are as frustrating as opening the washer at the end of a cycle to find the drum still full of water. Before you call for service, run through these four checkpoints — in this order — to narrow down what's actually happening.

Step 1: Inspect the Drain Hose

Water travels from the back of the machine through this hose to a standpipe or sink drain. A kink, a clog, or a blocked standpipe on the other end will all stop water from leaving the tub.

Fix: Work out any kinks and confirm the hose isn't pushed more than 6 inches into the standpipe — go deeper than that and you risk creating a siphon that pulls water back in.

Step 2: Check the Pump Filter on Front-Loaders

Behind the small hatch near the bottom front of a front-load washer sits a coin trap and pump filter. This one part is responsible for more no-drain calls than anything else on the machine.

Fix: Lay towels down first — you'll get a rush of water — then slowly back out the filter and clear whatever's caught inside.

Step 3: Read the Error Code

Newer washers will usually flash a drain-specific code (things like F21, OE, E20, or 5E, depending on the manufacturer). Pair your model number with that code online to zero in on the exact cause.

Step 4: Suspect the Drain Pump Motor

If the hose runs clear and the filter's clean but water still won't leave, the pump motor itself may have burned out. A telltale sign is a humming noise with no actual draining — the motor's trying to spin the impeller but can't.

Frequently Asked Questions

Where is the pump filter on a front-load washer?

Behind a small hatch near the bottom-front of the machine. Lay towels down first — there's usually a rush of residual water when you open it.

What does an F21, OE, E20, or 5E error code mean?

These are drain-related codes different manufacturers use for the same underlying problem: the machine detected it couldn't drain within the expected time.
