Appliance Water Damage

Washing Machine Leaking? Here's What to Do.

A leaking or overflowing washing machine can release water quickly and send it underneath flooring, behind baseboards, into walls, or through the ceiling below. Start by stopping additional water, then determine how far the moisture traveled.

Water Emergency Guide →
What should you do when a washing machine is leaking?

Stop the washing machine and additional water flow when it can be done safely. If the washer's hot and cold supply valves are accessible without entering standing water or encountering an electrical hazard, shut them off. Then determine where the water came from and how far it traveled. A small localized leak is different from a hose failure or overflow that sends water beneath flooring, into walls, or to the level below.

First Priority

Stop the water before focusing on cleanup

A washing machine can have multiple water sources, including hot and cold supply connections, internal components, the drain hose, and the household drain system.

If water is actively flowing, limiting additional water is the first priority when it can be done safely.

Once the flow has stopped, the next question is whether water remained near the appliance or spread into surrounding building materials.

Common Causes

Why is your washing machine leaking?

Where the water appears and when it leaks can help narrow down the possible source.

IN

Supply Hose or Connection

Hot and cold water hoses and their connections can loosen, deteriorate, split, or fail and release water behind the machine.

OUT

Drain Hose

A loose, damaged, disconnected, or improperly positioned drain hose can release water while the washer drains.

DRAIN

Drain or Standpipe Backup

Water may overflow from the standpipe or drain if the household drainage system cannot accept the washer's discharge.

DOOR

Door or Tub Seal

Front-loading washers can leak around a damaged or obstructed door seal, while other internal seals can also allow water to escape.

PUMP

Pump or Internal Component

Pumps, internal hoses, valves, tubs, and other components can develop leaks underneath or inside the appliance.

OVER

Washer Overflow

A filling, control, drainage, or other malfunction can result in water escaping the machine or laundry area.

Finding the Source

Where is the washing machine leaking from?

The location and timing of the water can provide useful clues, although the appliance may need inspection to confirm the actual failure.

Leak Location

Behind the Washing Machine

Check supply hoses, shutoff-valve connections, the drain hose, and the standpipe or drain area. Water may also run underneath the machine before becoming visible.

Leak Location

Under the Washing Machine

Water underneath the washer may originate from an internal hose, pump, tub, seal, or another component—or may have traveled there from a connection behind the machine.

Leak Timing

Leaks While Filling

Supply hoses, inlet connections, valves, internal fill components, or an overfilling problem may deserve investigation.

Leak Timing

Leaks While Draining

The drain hose, standpipe, household drain, pump, or internal drainage components may be involved.

What to Do

Washing machine flooded the floor? Follow these steps.

1

Stop the Machine

Stop the cycle if the washer is still operating and continuing to release water.

2

Stop the Water

Shut off the washer's water supply when the valves can be reached safely. A larger plumbing problem may require the home's main shutoff.

3

Consider Electricity

Do not enter standing water or handle electrical equipment when doing so could expose you to an electrical hazard.

4

Remove Visible Water

Once conditions are safe, remove standing water and wet contents rather than allowing water to remain on the floor.

5

Check Hidden Areas

Look beyond the puddle for moisture beneath flooring, behind trim, inside walls, cabinets, or on the ceiling below.

6

Dry Before Repairing

Address wet building materials before replacing flooring, patching drywall, reinstalling trim, or completing cosmetic repairs.

Safety

What if water is around the washer or electrical outlet?

Washing machines combine water with electrical power, so a significant leak can create conditions that require additional caution.

Do not step into standing water to reach a plug, outlet, appliance, electrical panel, or shutoff if doing so could expose you to an electrical hazard.

If you are unsure whether the area is electrically safe, stay out of the affected area and get appropriate professional help.

Don't reach through standing water to unplug the washing machine.

If electricity and water may be interacting, avoid the area rather than assuming it is safe because the washer has stopped running.

Floor Damage

What if washer water went underneath the flooring?

Water from a washing-machine leak can move underneath flooring even after the visible puddle has been removed.

Depending on the room, moisture may affect vinyl plank, laminate, hardwood, tile assemblies, carpet, padding, underlayment, or the subfloor.

Water can also wick into baseboards and drywall along the perimeter of the laundry area.

The top surface feeling dry does not necessarily establish that materials underneath are dry.

See our complete Water Under Flooring Guide .

Upstairs Laundry Rooms

What if an upstairs washing machine leaked?

A leak from an upstairs laundry area can affect much more than the floor directly around the washer.

Water can move through flooring and the subfloor into the floor-ceiling assembly below. It may affect insulation, framing, ceiling drywall, recessed lights, or other building components.

Check the room below for stains, dripping water, bubbling paint, sagging drywall, or other evidence that moisture traveled through the structure.

A sagging or bulging ceiling below deserves caution.

Keep people away from visibly unstable wet ceiling material, particularly if water is near electrical fixtures.

Hidden Water Damage

Signs the washing-machine leak caused more than a wet floor

Swollen baseboards Water can wick into trim and the lower portion of nearby walls.
Buckled or lifted flooring Some floor materials change shape after water reaches them or the materials underneath.
Soft drywall Water that reached a wall can affect drywall, insulation, and materials inside the wall cavity.
Musty odor Persistent odors after cleanup can be a reason to investigate whether materials remain damp.
Ceiling stain below Water appearing downstairs indicates that the loss traveled through part of the floor-ceiling assembly.
Water behind the washer Water can enter wall openings, gaps, penetrations, and other concealed areas behind the appliance.
Drying

How do you dry out water damage from a washing machine?

The appropriate drying process depends on how much water escaped and which materials became wet.

A small surface spill on a water-resistant floor is different from a hose failure that sends water beneath flooring, into drywall, or to the floor below.

Drying may involve removing standing water, moving wet contents, increasing controlled air movement, reducing humidity, accessing trapped moisture, and monitoring affected materials.

Don't stop at the visible puddle

A floor can look dry while water remains underneath flooring, baseboards, drywall, insulation, or the subfloor.

See our Water Damage Drying Time Guide .

Mold Concerns

Can a washing-machine leak lead to mold?

Persistent moisture can create conditions that support mold growth. This is why prompt drying matters when water reaches drywall, wood, carpet, padding, or other moisture-sensitive materials.

The goal should be to address the water source and wet materials rather than simply waiting to see whether visible mold appears.

Insurance

Does homeowners insurance cover washing-machine water damage?

Coverage depends on the policy and circumstances of the loss. The cause of the water damage can matter, as can exclusions, endorsements, deductibles, maintenance issues, and the specific property damage involved.

PIC

Document the Damage

Photograph the washer area, visible water, affected flooring, walls, ceilings, contents, and suspected source when it is safe to do so.

SRC

Identify the Cause

Keep information about the failed hose, drain problem, appliance component, or other source associated with the water release.

REC

Keep Records

Save relevant estimates, invoices, photographs, communications, and other documentation related to cleanup and repair.

Frequently Asked Questions

Washing machine leak FAQ

What should I do first if my washing machine is leaking?

Stop the machine and additional water flow when it can be done safely. If the washer's supply valves are safely accessible, shut them off. Then address visible water and determine how far it spread.

Why is my washing machine leaking from underneath?

Possible causes include a pump, internal hose, tub, seal, valve, or another internal component. Water from connections behind the washer can also travel underneath before becoming visible.

Why is my washing machine leaking from the back?

Supply hoses and connections, the drain hose, standpipe, or household drain are common areas to investigate when water appears behind the washer.

Why does my washing machine leak only when draining?

The drain hose, pump, standpipe, or household drainage system may be involved when leakage occurs specifically during the drain portion of the cycle.

Can a washing-machine leak damage the floor?

Yes. Water can affect finished flooring, adhesive, padding, underlayment, subflooring, baseboards, and nearby walls depending on the amount of water and how far it travels.

What if water got under vinyl plank or laminate flooring?

The finished surface may not show the full extent of moisture. Water can become trapped underneath flooring and affect underlayment or the subfloor.

What if my upstairs washing machine leaked through the ceiling?

Water may have affected the flooring, subfloor, floor-ceiling cavity, insulation, framing, ceiling drywall, and possibly electrical fixtures. Sagging or unstable wet ceiling material deserves caution.

Can a washing-machine leak cause mold?

Persistent moisture can create conditions that support mold growth, particularly when water reaches drywall, wood, carpet, padding, or other moisture-sensitive materials.

How long does washing-machine water damage take to dry?

There is no universal timeline. Water quantity, flooring, drywall, humidity, airflow, hidden moisture, and the drying method all affect how long the process takes.

Does homeowners insurance cover damage from a leaking washing machine?

It depends on the cause and circumstances of the loss and the terms of the policy. Sudden water damage and long-term leakage can be treated differently under policy language, so the actual policy and claim facts matter.

Was it more than a small washer leak?

If water reached flooring, walls, cabinets, or the level below, fixing the washing machine may be only one part of the problem. Determine how far the water traveled and whether affected materials need drying or repair.
