Washing Machine Not Draining? 7 Causes Ranked by Likelihood (With Tests)

The most common cause is a clogged pump filter. Check that and the drain hose before assuming the pump motor has failed.

Before you start

Unplug the appliance, shut off the water supply if relevant, and stop immediately if you smell burning. If in doubt, call a qualified professional.

On this page

The most common cause of a washing machine that won’t drain is a clogged pump filter, not a failed motor. Before assuming you need a replacement part, work through the checks below in order. They’re ranked from most to least likely based on how these cases typically resolve.

This page is part of our full washing machine troubleshooting guide. If your machine drains but then refuses to spin, see our not spinning guide instead, since the two symptoms share some causes but aren’t the same problem.

Repair or Replace?

Every cause on this page except a failed control board costs well under $90 in parts and under an hour of your time, so repairing is the clear choice. A control board runs $100–$250 in parts plus labor if you hire it out; on a machine older than 10 years, that’s usually the point where a new washing machine makes more financial sense than a third repair.

Whirlpool, GE, Samsung, LG, Maytag, Kenmore, Electrolux, and Bosch all place the pump filter and drain hose slightly differently, and reset procedures vary by model. Brand-specific guides are available for Whirlpool, GE, Samsung, and LG washers, covering the reset procedure, exact filter and pump location, and the error codes specific to each brand. If your machine shows a code, see Bosch E18 or Frigidaire E2.

If your machine drains fine but leaves a musty smell behind, that’s a different issue. See our Washing Machine Smells guide.

Frequently Asked Questions

Why is there a little water left in the drum even after a completed cycle?

A small amount of water pooled around the drain area or in the door gasket fold is normal on many models and keeps the pump seal from drying out. Water covering the bottom of the drum is not.

Can I run another cycle to try to clear a washing machine that won't drain?

Not until you've cleared the clog. Running another cycle on standing water just adds more weight on top of the blockage and can trigger the machine's overflow protection.

I just installed a new washing machine and it won't drain at all. What should I check first?

Check that the drain hose is inserted correctly into the standpipe and not pushed in so far that it's kinked, and confirm any shipping locks or transit bolts were removed during installation.

How can I check the drain pump without a multimeter?

You can't confirm a failed motor without one, but you can rule out a jam by checking whether the pump's impeller, visible once the filter is removed, spins freely by hand.

Is a loud humming sound during the drain cycle normal?

A brief hum is normal. A grinding or rattling sound usually means something rigid, like a coin or a bra underwire, is caught in the pump.

Tools needed

Probable causes

First checks

Step-by-step diagnosis

  1. Place towels and a shallow pan under the filter access door before opening it. Water will run out.
  2. Turn the filter counter-clockwise to remove it, clear out any debris, and check that the small impeller behind it spins freely by hand.
  3. If the filter is clear, disconnect the drain hose at the standpipe end and check for a clog with a flashlight; a shop vacuum on the hose end pulls out most soft blockages.
  4. With the machine unplugged, test the drain pump for continuity with a multimeter: a healthy pump motor typically reads a low resistance in the tens of ohms, though the exact figure varies by model, and infinite resistance means the motor has failed.
  5. If the pump tests fine but the machine never attempts to drain, the more likely cause is the door lock circuit or the control board, both professional-level repairs on most models.

When to call a professional

If the simple checks didn’t solve it, if the fix involves electrical wiring, gas, or the refrigerant circuit, or if you have any doubt at all: stop there and hand the appliance to a qualified repair professional.
