Standing water on a laundry room floor has a way of turning a normal afternoon into a small crisis. Is it going to ruin the flooring? Is it electrical? Is the machine dead? Take a breath, most leaks are not a disaster, and they are not necessarily a reason to buy a new washer. In fact, most washer repair calls we get for leaks turn out to be a quick, inexpensive fix. What matters right now is doing things in the right order. Here's that order.
Step 1: Stop the Damage (Do This First, Before You Diagnose Anything)
Before you try to figure out why it's leaking, stop it from getting worse.
- Shut off both water supply valves behind the machine. These are usually two small knobs on the wall, one hot, one cold.
- Cut the power. Unplug the washer if you can safely reach the cord without standing in water, or flip the breaker if you can't.
- Soak up standing water with towels or a wet/dry vacuum before it spreads to flooring, baseboards, or the wall behind the machine.
Only once the water is off and the floor is dry should you start looking for the source. Chasing the cause while water is still flowing just means more cleanup later.
Step 2: Confirm It's Actually the Washer
This sounds obvious, but it trips people up more than you'd expect. Before you tear into the machine, check that the water isn't coming from a nearby sink, a supply line under a utility tub, or a floor drain backing up. Run a short, empty cycle and watch closely. If water only appears while the washer is running, you've confirmed the source.
Step 3: Find Where the Water Is Coming From
This is the step that actually matters. Where the leak shows up tells you almost everything about what's wrong.
Leaking from the front of the machine
This points to the door seal on a front-load washer. Check the rubber gasket for tears, or for coins, hair ties, and grime trapped in the folds holding it slightly open.
Leaking from behind or underneath, no matter the cycle
Almost always a hose problem. Check the two inlet hoses at the wall connection and the drain hose at the standpipe for loose fittings or cracks.
Leaking only during the spin cycle
This usually means the drain pump or, on older machines, the tub bearing. If you hear grinding or rumbling while it spins, that's a strong sign it's the bearing, not the pump.
Water appearing even when the machine is off
The water inlet valve isn't sealing shut and is letting water trickle in on its own. Keep the supply valves closed until this is repaired; it can flood a room overnight.
Suds everywhere, water seeping around the door or drawer
Not a broken part. This is often oversudsing from too much detergent or an overloaded drum forcing water past the seals.
The machine rocks, shakes, or walks during spin, and that's when it leaks
An unlevel washer can be the actual cause, not just a symptom. Uneven feet let the drum shift during spin, which loosens hose connections or pushes water past the door seal. This shows up on both front-load and top-load machines sitting on uneven flooring.
Water is leaking but the machine seems to be draining slowly too
Check the drain pump filter before assuming the pump itself is broken. Most machines have a small access panel near the bottom front with a filter that traps lint, coins, and debris. A clogged filter backs water up and can push it out through the pump housing or hose connections, and it's a five-minute DIY clean, not a pump replacement.
Leaking from underneath and you hear a rattle or a metallic sound
A foreign object, like a coin, screw, or bra underwire, may have punctured the inner tub. This is more common than people expect and usually means the tub needs replacing, since a punctured tub isn't something you can patch reliably.
Step 4: Fix What You Can, Safely
A few of these are genuinely quick fixes:
- Inspect accessible supply hoses for visible damage without moving a heavy appliance. Follow the model’s care guide for replacement intervals and connection instructions; arrange professional help when access is unsafe.
- Clean the door gasket: Wipe every fold with warm water and check for anything trapped in the seal.
- Cut back on detergent: Switch to an HE detergent for front-load and newer top-load machines, and use less than the cap suggests.
- Reduce load size: An overstuffed drum puts pressure on seals that were never built to hold water back under that kind of weight.
- Clean the dispenser drawer: Most slide out with a small tab. Rinse away hardened detergent and let it dry.
- Level the machine: Use a bubble level on top of the washer and adjust the front feet until it reads level side to side and front to back. A machine that rocks during spin will keep loosening things over time.
- Clean the drain pump filter: Open the small access panel near the bottom front, place a shallow pan underneath, and unscrew the filter to clear out lint, coins, or debris. Check your owner's manual for the exact location; it varies by brand.
Step 5: Know When It's Time to Call Someone
Some causes are not DIY territory, and trying to force it usually turns a $150 repair into a much bigger one:
- A water inlet valve that won't shut off completely
- A cracked or failing drain pump
- A worn tub seal or bad bearing, especially with grinding noise on spin
- A punctured or cracked inner tub from a foreign object
These involve internal disassembly or the home's water supply line, and a wrong move can mean a worse leak, not a fixed one. If your leak matches one of these, it's worth scheduling washing machine repair with a licensed technician before it causes real water damage.
Is It Worth Repairing?
A repair decision depends on the diagnosis, appliance condition, repair history and written quote. Ask the manufacturer about any remaining warranty coverage and compare the complete repair and replacement costs.
Keep It From Happening Again
A little routine maintenance goes a long way here:
- Inspect accessible supply hoses for visible damage without moving a heavy appliance. Follow the model’s care guide for replacement intervals and connection instructions; arrange professional help when access is unsafe.
- Wipe down the door gasket after each load to prevent mold and buildup.
- Don't overload the drum; give clothes room to tumble.
- Use the correct detergent type and amount for your machine.
- Leave the door open between loads so the seal and drum can fully dry.

Frequently Asked Questions
Is a leaking washing machine dangerous?
It can be, mainly from water damage to flooring and walls, and from slip hazards. If water is anywhere near an outlet or the power cord, cut the power before doing anything else.
Can I keep using the washer while I figure out the leak?
If it's a slow drip from a loose hose connection, one more short test cycle is usually fine. Stop using it immediately if water appears when the machine is off, or if it's leaking from underneath during spin.

Do you repair all washing machine brands?
Yes, including Samsung, LG, Whirlpool, GE, Bosch, Electrolux, Maytag, and Kenmore. Call us even if you don't see your brand listed.
My washing machine is brand new and already leaking, what's going on?
This is usually an installation issue, not a defect. Check that the shipping bolts were removed from the back of the machine, that the inlet hoses are tightened all the way, and that the drain hose is properly seated in the standpipe and not pushed in so far it siphons water back out. If everything checks out and it's still leaking, contact the manufacturer since it's likely still under warranty.
Is a leaking front-load washer different from a leaking top-load washer?
The most likely causes differ. Front-load machines leak from the door seal far more often, since they rely on that gasket to hold water in during the wash. Top-load machines rarely have that issue but are more prone to leaks from hose connections, the pump, or an unbalanced load shifting the tub.
