Why won’t my washer drain? Causes and fixes

By: Reliable Parts • July 2026

A washer that won’t drain is most often caused by a clogged drain pump filter, a blocked or kinked drain hose, or a failed drain pump motor. Foreign objects like coins, socks, and lint commonly lodge in the pump impeller and stop water from clearing. On some top-load washers a failed lid switch also prevents draining. Identify your washer’s model number to order the correct replacement parts.

Safety information

Unplug the washer before opening the pump filter or removing any hose. The filter housing and tub hold standing water - have towels and a shallow pan ready. Never bypass the lid switch or door lock to force a drain cycle with panels removed.

Most common causes

  1. Clogged drain pump filter — lint, coins, and small clothing items collect in the filter or coin trap and block flow; the most common cause on front-load washers.
  2. Blocked or kinked drain hose — a hose crushed against the wall or clogged with lint restricts or stops drainage.
  3. Foreign object in the pump impeller — debris that passes the filter can jam the impeller so the pump hums but doesn’t move water.
  4. Failed drain pump motor — the pump runs weakly, intermittently, or not at all and must be replaced.
  5. Failed lid switch or door lock — some washers will not enter the drain cycle without a closed-lid or locked-door signal.
  6. Drain standpipe problem — a house drain that is clogged, or a standpipe that is too tall or too short, can cause slow draining or siphoning.

Step-by-step diagnosis

  1. Check the drain hose for kinks. Pull the washer forward and confirm the hose isn’t crushed behind the machine, and that it enters the standpipe without being pushed in so far that it seals against the pipe.
  2. Clean the drain pump filter. On front-loaders, open the access door at the bottom front, place towels down, and unscrew the filter. Remove lint, coins, and debris. This single step resolves a large share of no-drain calls.
  3. Inspect the pump impeller through the filter opening. Rotate it with a finger - it should turn in distinct increments with light magnetic resistance. A jammed or free-spinning impeller indicates an obstruction or a stripped impeller.
  4. Listen to the pump during a drain cycle. A humming pump that moves no water is jammed or failed. A silent pump points to a power, switch, or control problem rather than the pump itself.
  5. Check the tub-to-pump hose. Small items that escape the drum - socks, baby clothes - often lodge in the corrugated hose between the outer tub and the pump. Remove the hose clamp and inspect.
  6. Test the lid switch or door lock. If the washer won’t drain and also won’t spin, the interlock is a likely common cause. Test for continuity and replace if it fails.
  7. Verify the house drain and standpipe drain freely by pouring a bucket of water down the standpipe. If it backs up, the problem is plumbing, not the washer.

Replacement parts to consider

Common parts for a no-drain condition: drain pump, drain hose, pump filter/coin trap, tub-to-pump hose, lid switch, door lock assembly. Enter your washer’s model number on reliableparts.com for the exact parts for your specific model.

Related FAQs

How do I force my washer to drain?

Most front-load washers can be drained manually through the pump filter door at the bottom front: place shallow pans and towels down, open the small drain tube or slowly unscrew the filter, and let gravity empty the tub. Then clean the filter before running another cycle.

Why is my washer full of water and won’t spin?

A washer holding water that won’t spin is protecting itself - most models refuse to spin until the tub drains. Fix the drain problem first: clean the pump filter, check the hose for kinks, and inspect the pump. Once the water clears, spin normally resumes.

How much does a washer drain pump cost?

A replacement drain pump typically costs $25-80 for most brands, and on many front-load washers it is accessible from the front or bottom of the machine without major disassembly. Professional replacement generally runs $150-300 including labor.

How often should I clean my washer’s drain pump filter?

Clean the pump filter every one to three months, more often if you wash pet bedding or heavily linting items. Regular cleaning prevents most no-drain failures and also reduces odors from trapped debris decomposing in the filter housing.

Can a clogged house drain make my washer stop draining?

Yes. If the standpipe or the branch drain it feeds is clogged, water backs up and the washer appears to have failed. Test by pouring a bucket of water down the standpipe - if it rises or drains slowly, clear the house drain before replacing washer parts.
