Washer Leaking Water: Common Causes and What to Check
A leaking washer is a different problem than one that won't drain: water is escaping the machine itself rather than staying stuck inside it. Here's what usually causes it and which checks are safe to do yourself before assuming the worst.
Request ServiceDoor seal & gasket
A worn door seal is one of the most common reasons a washer leaks. Over time, detergent residue, lint, pet hair, and small clothing items can lodge in the folds of the gasket, preventing it from forming a watertight seal.
Hose connections
Loose or damaged hoses are a common source of large leaks underneath the washer, so checking both the external supply hoses and the internal drain connection for corrosion or a loose fitting is worth doing early.
Two more common causes
Detergent and load size
Detergent overuse
Too much detergent can cause oversudsing, which can clog the overflow tube and lead to a leak. It's one of the easiest causes to rule out, since it just means using less next load.
Overloading
Overloading can force water past the door seal or cause excessive movement that leads to leaks, and repeated overloading wears the machine down faster over time even when it isn't leaking yet.
Worn internal pump seal
A worn pump seal is a less common but real cause, usually showing up as a slow leak underneath the machine that isn't tied to a specific cycle stage. This one typically needs a technician to access and replace.
Quick checks before assuming the worst
- Inspect the gasket folds for trapped debris or residue
- Confirm hose connections are snug at both ends
- Note whether the leak happens during fill, wash, or spin specifically
- Try a load with less detergent and see if it stops

Why the timing of the leak matters
A leak that only happens during fill usually points to a supply hose or inlet valve, while a leak during spin more often points to the door seal or an overloaded drum. Noticing which stage the water shows up during narrows down the likely cause well before anyone opens the machine.
When it's more than a quick fix
A leak that keeps happening after the gasket is clean, hoses are snug, and detergent amount is corrected is more likely to be an internal seal or pump issue, which generally isn't a DIY repair.
Questions
Washer leak questions
Is a leaking washer the same problem as one that won't drain?
No. A washer that won't drain keeps water trapped inside the tub. A leaking washer is losing water it shouldn't be losing at all. They can occasionally share a root cause, but they're different symptoms and usually point to different parts of the machine.
Can too much detergent really cause a leak?
Yes. Oversudsing from too much detergent is one of the most common and easiest-to-fix causes of a washer leak, and cutting back to the amount recommended on the detergent bottle often resolves it on its own.
Is it safe to keep using a washer that's leaking?
For a small, occasional leak it's usually fine to run one more load while sorting out the cause, as long as the area around the machine is dry and safe. A steady or growing leak is worth pausing on, since standing water near an electrical connection is a real hazard, not just a mess.

Still seeing water where it shouldn't be?
Share which part of the cycle the leak happens during and roughly how much water. The more specific the request, the easier it is for a local pro to help.
