Washing Machine Leaking? Find the Source Before It Spreads
A washing machine leak can damage flooring quickly, so start with containment instead of another test cycle. The leak location—behind, under, or at the front of the washer—usually points to the next safe check. Place towels around the machine, photograph the source if you can see it safely, and avoid moving a heavy washer across a wet floor. A leak that begins only at a certain point in the cycle is especially useful information for a repair technician. A drip during fill often points to a supply connection, while water during draining can point to the drain hose or pump area. Front-door drips can be caused by detergent suds or a damaged gasket. If water is spreading toward a wall outlet, lower level, or finished flooring, prioritize shutting off water and getting professional help before attempting any further inspection. **Unplug the washer and turn off water if the leak is active or near an outlet.**

Common Symptoms
- Water appears under or behind the washer
- Leak occurs only during fill, wash, drain, or spin
- Front-load door area drips
- Washer overflows with suds
- Laundry room floor is wet after a cycle
Most Likely Causes
- 1
Loose or Worn Supply or Drain Hose
A hose connection can drip during fill or drain, especially if a rubber washer is worn, a clamp is loose, or the hose is kinked.
- 2
Detergent or Door-Seal Overflow
Too much HE detergent, blocked dispenser passages, or debris on a front-load door gasket can push water out the front.
- 3
Internal Pump, Tub, or Seal Leak
Water from beneath the cabinet can indicate a pump, tub-to-pump hose, tub seal, or internal component that needs appliance service.

Quick DIY Checks
Do not operate or plug in a washer while water is near the outlet, cord, or electrical connections. Shut off water and power first, then dry the area.
Never reach underneath a washer or remove cabinet panels while it is plugged in. Internal leaks can involve moving parts, sharp edges, and electrical components.
- 1Step 1 — Stop the cycle and contain water. Press pause or cancel, unplug the washer if it is safe to reach without standing in water, and close both supply valves. Mop up water before inspecting.
- 2Step 2 — Identify when and where it leaks. Dry the floor, then look for moisture at the supply connections, drain hose, detergent drawer, door gasket, and visible hose ends. Do not run a full cycle to chase an active leak.
- 3Step 3 — Check external hoses. Hand-tighten a visibly loose connection only; inspect for cracked hoses, damaged rubber washers, kinks, or a drain hose that has slipped from the standpipe. Replace damaged hoses instead of taping them.

Est. Repair Cost
$15–$80 for hoses, washers, or basic maintenance; $180–$650 for pump, gasket, or internal leak repair

Frequently Asked Questions
- Why does my washer leak only when draining?
- A drain hose, standpipe connection, or internal drain pump area is more likely. Stop the machine, inspect accessible hose connections, and call for service if water comes from under the cabinet.
- Can too much detergent make a washer leak?
- Yes. Excess suds can overflow the dispenser or door area, especially in high-efficiency machines. Use only HE detergent and the manufacturer-recommended amount.
- Is a leaking washing machine an emergency?
- Treat active water near electricity, a large leak, or water spreading to other rooms as urgent. Shut off water and power, contain it safely, and arrange repair.
