Quick answer
Where the water appears tells you most of the story. A leak at the front of a front-loader is usually the door boot seal or too many suds. A leak at the back points to the fill hoses or the drain standpipe, and water under the middle often comes from the drain pump or a tub seal.
A leaking washer can soak a subfloor or run under a wall before anyone notices, especially in a garage laundry or an upstairs condo. Shut off the water at the valves behind the machine until you find the cause.
Then dry the floor completely, run a short cycle and watch. Fresh water on a dry floor is much easier to trace than an old puddle.
Causes, from most to least likely
1.Drain standpipe overflowing
The washer pumps water out quickly. If the standpipe or laundry sink drains slowly, water backs up and spills over the top behind the machine. It looks like a washer leak but it's a plumbing clog.
- Check it yourself
- Pull the washer out and watch the standpipe during the drain. If water rises and spills over, the drain is slow. Make sure the hose isn't pushed so deep that it seals the pipe.
- The fix
- Clear the drain line, which is a job for a plumber, or set the hose at the right depth. The washer itself is fine.
2.Loose or worn fill hoses
The hot and cold supply hoses have rubber washers at each end. They harden and crack with age, and the connections loosen when the washer is moved. Old rubber hoses can also split or bulge.
- Check it yourself
- With the water on, look at both ends of each hose for drips. Snug the couplings by hand plus a quarter turn. Replace any hose that is bulging, cracked or more than about five years old.
- The fix
- New hose washers or braided stainless hoses solve it. It's an inexpensive part you can do yourself.
3.Torn or dirty door boot seal (front-loaders)
The rubber boot between the door and the tub can tear from zippers, underwire or coins. Lint, hair and detergent residue in the folds can also break the seal and let water wick out during the wash.
- Check it yourself
- Open the door and pull back the folds of the boot. Look for tears, holes and debris, especially at the bottom. Wipe the door glass and the boot lip clean.
- The fix · typical $220 – $360
- A dirty seal just needs cleaning. A torn boot is replaced, which means removing the front panel and two clamps.
4.Too much detergent
Excess suds push foam out of vents and past the door seal. HE washers use very little water, so the same amount of soap that worked in an old top-loader causes a foam overflow in a new one.
- Check it yourself
- If you see foam at the leak or inside the door, cut back on detergent. Use only HE soap and measure it. Pods count as a full dose.
- The fix
- Run a rinse cycle with no detergent to clear the foam. No part needed.
5.Drain pump or filter leak
A drain filter that isn't screwed in fully, a cracked filter housing, or a worn pump seal will drip from the lower front or under the machine, usually during the drain or spin.
- Check it yourself
- Make sure the drain filter cap is tight and its rubber gasket is in place. Look under the front edge with a flashlight during the drain cycle.
- The fix · typical $170 – $290
- A loose filter costs nothing. A cracked housing or failed pump is replaced.
6.Cracked water inlet valve
The inlet valve at the back of the washer is plastic. It can crack, or its internal seals can fail, and it drips even when the washer is off.
- Check it yourself
- Look for drips where the hoses connect at the back with the washer idle. A puddle that appears while the washer isn't running points here or to the hoses.
- The fix · typical $160 – $260
- The valve is replaced and checked for leaks with water pressure on.
7.Tub seal, bearings or a cracked tub
The rear tub seal keeps water away from the main bearings. When it fails, water drips from under the middle of the machine, often with rusty streaks, and a loud roar during spin soon follows as the bearings go.
- Check it yourself
- Look for rust-colored water under the washer and listen for a grinding roar during spin. These two together usually mean the bearings are going.
- The fix
- This is a big repair that often means taking the tub apart. On older washers it's usually not worth it, and we'll tell you before you spend money.

What the warranty covers →Common questions
Why is my washer leaking from the bottom?
+
Under the front, the usual sources are the drain filter cap, the drain pump or a loose hose clamp. Under the middle, a tub seal or cracked tub is more likely. Dry the floor and run a short cycle to see when the water appears.
Is a leaking washer safe to use?
+
Not until you know the source. Water can reach the motor and wiring, and slow leaks can damage the floor. Shut off the supply valves and unplug the washer until it's checked.
My washer only leaks during the drain cycle. What does that mean?
+
It points to the drain side: the standpipe, the drain hose connection, the drain filter or the pump. Watch the standpipe first, because an overflowing drain is the most common cause.
How often should washer hoses be replaced?
+
Many manufacturers suggest about every five years. Braided stainless hoses resist bursting better than plain rubber. Turn off the supply valves if you'll be away for a while.
Should I put a drain pan under my washer?
+
It's a good idea for second-floor laundry rooms and condos. A pan with a drain line helps with small leaks. It won't stop a burst hose, so an automatic shutoff valve is worth considering too.
