Washer drain troubleshooting

Washer Won't Drain Water? Check the Filter and Hose First

If a washer won't drain water, run one Drain/Spin command and listen for water flow, a steady hum, grinding, or silence. If water stays put, check load balance, the drain hose, and the pump filter before you blame the pump or control board.

A good clue is where the water acts up: silence, a steady hum, rough grinding, or water backing up at the standpipe each points to a different next check.

Work from the outside in: cycle command, load balance, drain hose, cleanout filter, pump sound.

Don’t start with: Do not buy a washer drain pump first. Prove the hose, cleanout filter, pump cavity, and house drain can pass water before parts go in the cart.

Tub still full?Cancel the cycle, choose Drain/Spin, and listen for water flow, humming, grinding, or silence.

Pump hums but water stays put?Unplug the washer, control the water, then inspect the hose and pump filter before blaming the pump.

Do this first

Stop running cycles if water is rising, leaking onto the floor, or backing up from the standpipe.
Unplug the washer before opening a service panel, pump filter, hose connection, or lower cabinet area.
Keep towels and a shallow pan in place before loosening any cleanout cap or hose clamp.
Open pump filters slowly; a full tub can release more water than a small pan can hold.
Do not reach into the pump area with power connected or while the machine is trying to drain.
Do not pour chemical drain cleaner into the washer, pump filter, hose, or laundry standpipe.
Call service if you smell burning, see melted wiring, or the washer trips a breaker during drain.

60-second drain sort

Does Drain/Spin start at all?

If nothing starts, confirm the cycle was canceled, the lid or door is firmly shut, and the washer is not paused before opening the cabinet.

Is the load one heavy wet lump?

Redistribute it or remove a few heavy items. Some washers will not reach a proper spin and drain finish with a badly bunched load.

Do you hear a steady hum?

A steady hum with no water movement usually means the pump is trying against debris, a packed filter, or a blocked hose. Unplug the washer, contain the water, then recheck the filter, pump cavity, and hose before pricing a pump.

Is the pump silent during drain?

A silent pump moves electrical, door/lid sensing, and pump diagnosis higher on the list, but only after the washer is actually commanding drain.

Does the standpipe or sink back up?

That points outside the washer. Stop the washer and clear the laundry drain path before buying washer parts.

Is the hose and filter path clear?

Now pump failure becomes a reasonable parts branch, especially if the pump hums, leaks, grinds, or has a damaged impeller.

Follow the water before buying a pump

Look for the first clue: standing water, cleanout debris, or a hose route that cannot pass water.

Front-load washer with standing water and wet clothes after the cycle failed to drain — Standing water and soaked clothes do not prove the pump is bad. Run one drain command and listen before opening anything.

Washer pump filter removed with lint and small debris blocking the cleanout area — A dirty cleanout filter is a real drain restriction. Drain slowly, clear debris, and check the cavity before replacing parts.

Washer drain hose routed to a laundry standpipe behind the machine — The hose and standpipe matter. A crushed hose, airtight fit, or backing-up laundry drain can mimic a failed washer pump.

Before you buy anything

Copy the full model number from the washer tag and prove where the water stops. A drain hose belongs in the cart only if it is split, crushed, permanently kinked, or blocked beyond cleaning. A drain pump comes later, after the hose, filter, pump cavity, and standpipe clues point there.

What is probably happening

The washer must finish the cycle, power the pump, pass water through the hose, and discharge into the laundry drain.

Cycle or latch state: the washer may be paused, still soaking, or waiting for the lid or door signal before it ever powers the pump.
Load balance: one heavy item can keep the washer from reaching the spin behavior that normally finishes the drain portion.
Hose restriction: a crushed hose, blocked hose end, or hose shoved too tightly into the standpipe can stop flow outside the cabinet.
Pump-filter debris: lint, coins, hair pins, small garments, and fabric scraps can pack the cleanout or jam the impeller.
House drain problem: water backing up at the standpipe or laundry sink means the washer may be pumping into a blocked drain.
Pump failure: the pump is more believable after the visible drain path is clear and it still hums, grinds, leaks, or stays dead during drain.

What not to do

A full washer can turn a small repair into a wet electrical problem. Slow down and contain the water first. Order a part only after the clue is specific: a split or crushed hose, a packed cleanout, or a clear drain path with the pump still humming, grinding, leaking, or silent.

Do not keep restarting full cycles when the tub is already full of water.
Do not pull a pump filter cap all the way out until you have a pan, towels, and a plan for the water.
Do not assume a humming pump is bad; a jammed impeller or blocked hose can make a good pump sound stuck.
Do not tape a split drain hose or force a cracked plastic cleanout cap back into service.
Do not seal the drain hose airtight in the standpipe; the washer drain still needs the correct air gap and routing from the model instructions.
Do not use chemical drain cleaner in the washer or standpipe, especially before opening a hose or cleanout.

Step-by-step fix

Work in the same order water leaves the machine. Stop as soon as the clue points clearly outside the washer or toward a part that can be matched by model number.

Step 1: Cancel the current cycle. Choose Drain/Spin or Spin Only, close the lid or door firmly, press Start, and listen for the first minute.
Step 2: If the load is one heavy wet bundle, redistribute it or remove a few items, then try Drain/Spin again.
Step 3: Unplug the washer. Pull it forward only far enough to see the drain hose without stretching supply hoses or the power cord.
Step 4: Look for a crushed hose, sharp bend, blocked outlet end, or hose pushed too far into the standpipe. Correct the routing before opening the machine.
Step 5: If your model has a pump filter or service drain, put towels and a shallow pan down first. Drain slowly, then remove lint, coins, pins, and fabric debris.
Step 6: With the filter back in place and the area dry, run Drain/Spin again. A strong drain sound means the restriction was likely cleared.
Step 7: If the path is clear but the pump hums, grinds, leaks, or stays silent during a real drain command, move to model-specific pump diagnosis or service.

Read the drain result

One controlled Drain/Spin attempt tells more than the first guess. If water leaves fast, do a leak check. If the pump hums and water barely moves, recheck the filter, pump cavity, and hose. Price a model-matched part only after that path is clear and the pump still hums, grinds, leaks, or stays silent.

What you see or hear	What it usually means	Next move
Drain/Spin starts and water leaves fast.	The washer can pump when the command and load are right.	Run a short rinse and drain, then inspect for leaks.
Pump hums but water barely moves.	Debris, a jammed impeller, or a blocked hose is still likely.	Unplug it and recheck the filter, pump cavity, and hose.
Pump is silent during a real drain command.	The pump may not be powered, or the washer may be held out by a door, lid, wiring, or control issue.	Stop before live electrical work and use model-specific service steps.
Water backs up at the standpipe or sink.	The laundry drain cannot accept the discharge.	Stop the washer and clear the plumbing side before replacing washer parts.
Filter is packed with lint, coins, or fabric.	The drain restriction was inside the cleanout path.	Clean it, reinstall it fully, and run a leak check.
Hose is split, brittle, or crushed flat.	The hose itself is now part of the failure.	Replace the hose with the correct model-fit part.

When the standpipe is the real problem

A washer can look broken when the laundry drain is actually the restriction. That clue usually shows up outside the machine, not in the pump filter.

Watch the standpipe or laundry sink during a short drain attempt from a safe distance.
If water rises in the standpipe, gurgles hard, or spills from the sink, stop the washer.
Do not keep running the pump into a backing-up drain; it can flood the laundry area and hide the original clue.
Check only accessible hose routing first. Leave drain-line snaking, cleanout work, or repeated backups to a licensed plumber.
After the home drain is clear, run a short washer drain cycle again before buying a pump.

Replacement Parts

Compare parts only after the symptom points to one. Match the full model number before ordering. A hose makes sense only if it is split, crushed, brittle, or still blocked after cleaning. A pump comes later, after the drain path is clear and it still hums, grinds, leaks, has a broken impeller, or stays silent.

Washer drain hose

Helps when: The hose is split, crushed, permanently kinked, brittle, too short for safe routing, or blocked beyond cleaning.

Skip it when: The hose only needed to be straightened, reseated loosely in the standpipe, or cleared at the outlet end.

Washer drain pump

Helps when: The drain path is clear, but the pump still hums, grinds, leaks, has a broken impeller, or stays silent.

Skip it when: You still have a visible clog, a backing-up standpipe, or an unconfirmed cycle, lid, or door-sensing issue.

Prove the repair

Do not call it fixed the moment water leaves once. A clean repair drains, spins, and stays dry around every area you opened.

Run a short rinse and drain cycle with the washer in its normal position.
Look under the front cleanout, rear hose, and any clamp you touched for fresh drips.
Watch the standpipe or laundry sink during discharge to make sure water does not back up.
Listen for a smooth drain sound instead of a strained hum, rough grind, or repeated clicking.
Run one normal load after the floor is dry enough that a new drip would be obvious.
Write down the model number and what you found if the symptom returns; that record helps avoid buying the wrong part.

FAQ

Why is my washer full of water after the cycle ends?

The washer either never reached a real drain command, could not pump through the hose and filter path, or discharged into a blocked laundry drain. Start with Drain/Spin, load balance, hose routing, and the pump filter.

Does a humming washer mean the drain pump is bad?

Not by itself. A hum often means the pump is trying to move water against a clog, packed filter, jammed impeller, or blocked hose. The pump becomes a better suspect after those paths are clear.

Should I open the pump filter while the washer is full?

Only slowly and with the washer unplugged, towels down, and a shallow pan ready. A full tub can release water fast, so stop if you cannot control the flow.

Can an unbalanced load keep a washer from draining?

It can keep the washer from finishing the drain and spin behavior correctly. A heavy blanket, rug, or bunched load is worth redistributing before you open a hose or filter.

How do I know it is the washer and not the house drain?

If water reaches the standpipe or laundry sink and backs up, the plumbing side is the lead clue. If water never leaves the tub, stay with the washer hose, filter, pump cavity, and pump behavior.

Can I use drain cleaner in the washer drain hose?

No. Chemical drain cleaner can damage washer parts and create a hazardous spill when a hose or cleanout is opened. Clear accessible debris manually or call the right pro for the drain line.

Which part should I consider first?

A hose comes first only when it is damaged or blocked beyond cleaning. A pump comes later, after the hose, cleanout filter, pump cavity, and standpipe all point away from a simple restriction.

What if the washer drains but clothes are still soaked?

That may be more of a spin problem than a drain blockage. First make sure the tub empties fully; then look at load balance, spin behavior, and any lid or door sensing issue.

Where is the pump filter on my washer?

Many front-load washers have a lower front access door, but not every model has a homeowner-removable filter. Use the model manual before prying panels or removing parts.

When should I call a pro?

Call for burning smells, breaker trips, melted wiring, a pump area leak, a washer too heavy to move safely, a backing-up laundry drain, or any diagnosis that requires live electrical testing.
