Washer Not Draining Completely: Causes and How to Fix It

Washer not draining completely usually means the machine is removing some water but not enough to leave the drum fully clear at the end of the cycle.

If your washer is not draining completely, it may leave a shallow pool in the drum, wet laundry after the cycle, or a damp smell that suggests water is still being left behind. In some cases, the washer drains slowly enough to finish the cycle, but not well enough to empty properly.

Why Is My Washer Not Draining Completely?

A washing machine that does not drain completely is often dealing with a partial blockage, restricted drain hose, dirty pump area, weak drain pump, too many suds, or a slow household drain line. If your machine is showing a brand-specific code, you can also compare it with the LG Washer OE Code, Samsung Washer 5C Code, Whirlpool Washer F21 Code, Whirlpool Washer F9 E1 Code, Whirlpool Washer DRN Code, Maytag Washer F9 E1 Code, Bosch Washer E18 / F18 Code, GE Washer E2 Code, or GE Washer E23 Code.

Quick Answer: Why a Washer Is Not Draining Completely

A washer usually fails to drain completely because water can still get out, but not fast or fully enough to clear the drum the way it should. The most common reasons are a partial drain blockage, pump restriction, weak drain pump, clogged filter, or a drain hose setup that slows water flow.

In many cases, the washer is not dealing with a total drain failure. It is dealing with an incomplete drain path.

Most Common Reasons a Washer Is Not Draining Completely

Partially clogged drain hose
Dirty pump filter or pump clean-out area
Lint, coins, or debris in the drain path
Weak or slowing drain pump
Too many suds slowing water removal
Household standpipe or drain line restriction
Drain hose installed incorrectly

Signs Your Washer Is Not Draining Completely

A partial drain problem often looks less dramatic than a total drain failure. Common signs include:

A small amount of water left in the drum
Clothes coming out wetter than normal
The washer finishing the cycle but still smelling damp
Drain performance getting worse over time
The machine taking longer than usual near the end
Water left in the bottom after spin

Sometimes the washer technically “drains,” but not well enough to leave the tub fully clear.

What to Check First When a Washer Is Not Draining Completely

1. Look for standing water in the bottom of the drum

If only a small amount remains, the problem may be partial rather than total. That usually points to a restriction, not always a completely dead pump.

2. Check the drain hose behind the washer

Look for bends, crushing, or a hose path that may be slowing water flow without stopping it entirely.

3. Check the filter or pump area

Coins, lint, hair, and residue can collect there and reduce drainage enough to leave water behind.

4. Think about detergent use

Too many suds can slow drainage and make it seem like the washer has a mechanical problem when the real issue is foam and residue.

How to Fix a Washer That Is Not Draining Completely

Most partial drain problems should be approached by clearing the drain path first before assuming the pump itself has failed.

Inspect and straighten the drain hose

If the hose is pinched or partly restricted, correcting its position may restore full drainage.

Clean the pump filter or clean-out area

If your washer has an accessible filter, remove debris carefully and check for anything blocking water flow.

Reduce excess detergent use

If the washer is producing too many suds, use less detergent and make sure it is the correct type for the machine.

Run a short drain or rinse cycle

After clearing the obvious restriction, test the washer again and see whether the remaining water problem improves.

When the Drain Pump May Be Weak

If the hose and filter area are clear but the washer still leaves water behind, the drain pump may be weakening rather than completely failed.

Possible signs include:

The washer drains, but very slowly
The remaining water problem gets worse over time
The pump sounds weaker or different than before
The machine leaves wet clothes even with balanced loads

At that point, the issue may be more than a simple clog.

When Suds or Residue Are the Real Cause

Sometimes the washer is not draining completely because the water path is being slowed by foam and residue rather than a hard blockage.

Possible signs include:

Soapy or foamy water remains inside
The problem happens more with certain detergents
The washer also smells sour or musty
The machine has occasional SUD-related symptoms

In those cases, compare the issue with Whirlpool Washer SUD Code, Maytag Washer SUD Code, and Washer Smells Bad.

How Brand Codes Connect to Incomplete Draining

Many washer brands use drain codes even when the problem is partial, not total. If your washer display shows a code, these pages may help:

These codes are different by brand, but they often point to the same restricted drain-side causes.

How to Reset a Washer After a Partial Drain Problem

Once you have corrected the obvious restriction, a simple reset may help the washer restart normally.

Turn the washer off
Unplug it from the power source
Wait about 5 minutes
Plug it back in
Run a short drain or rinse cycle

A reset can clear a temporary interruption, but it will not permanently fix a blocked hose, dirty filter, or weak drain pump.

Is a Washer That Is Not Draining Completely Serious?

Usually it is not a major disaster if the cause is a partial clog or too much suds. In many cases, the fix is simple once the drain path is cleaned properly.

It becomes more serious when:

The amount of leftover water gets worse over time
Clothes keep coming out much wetter than normal
The washer smells damp or sour after cycles
The same issue happens every wash
A reset does not help

When to Call a Technician

You may need professional service if:

The hose and filter area appear clear but the washer still leaves water behind
The pump sounds weak or abnormal
The same problem returns repeatedly after cleaning
You suspect a weak pump or internal drain restriction

At that point, the problem is more likely to involve the drain pump or internal drain path than basic maintenance.

FAQ

Why is there still water left in my washer after the cycle?

The most common reasons are a partial blockage, dirty filter, weak pump, or drain hose restriction.

Can too much detergent cause incomplete draining?

Yes. Excess suds can slow water removal and leave moisture behind.

Is partial draining still a pump problem?

Sometimes. A weak pump may still move some water, but not enough to clear the drum fully.

Will unplugging the washer fix incomplete draining?

Only if the issue was a temporary interruption. A reset will not fix a physical restriction or a weak pump.

Final Thoughts

If your washer is not draining completely, start with the basics first: inspect the hose, clean the filter or pump area, reduce excess detergent, and test the drain cycle again. In many cases, the issue is a partial restriction, not a total washer failure.

If the problem keeps coming back, the washer may have a weak drain pump or a deeper internal drain issue that needs closer diagnosis. If the machine stops draining entirely, move next to Washer Won’t Drain.
