A washer leaking from underneath rarely tells you the source — water tracks across the floor pan and drips out a corner that has nothing to do with the actual failure. We find the source first. Resetting and re-running the cycle to 'see where it drips' is how floors warp and subfloors rot.

Quick answer
If your washer is leaking from the bottom, 5 sources cover ~95% of what we find: (1) door boot / bellow tear on front-loaders — $245–$385; (2) failed drain pump or pump seal — $235–$345; (3) cracked or loose drain hose — $185–$265; (4) failed water inlet valve (drips during fill or when off) — $215–$315; (5) tub seal or outer tub crack — the expensive one, $485–$785. We find the source before quoting. Flat $149 trip fee waived on approval. 1-year written warranty.
Root causes, ranked by what we find
What it is: Front-load washers leak from the front-bottom when the rubber door bellow has a tear or pin-hole — usually from a wire or coin trapped in the lower fold. Water sprays during the spin cycle. Universal failure on LG, Samsung, Whirlpool, Maytag, GE, Electrolux, Frigidaire front-loaders at year 4–8.
Fix: Replace OEM door bellow, clean the lower drain fold, verify with full cycle test.
Typical all-in: $245–$385 all-in
What it is: Leak appears during drain phase, water under the front-center of the washer. The drain pump housing has cracked, or its shaft seal has failed and weeps each cycle.
Fix: Replace OEM drain pump assembly. Inspect filter housing and clean foreign debris.
Typical all-in: $235–$345 all-in
What it is: Leak only during fill (cold or hot supply hose) or only during drain (corrugated drain hose at the tub or pump fitting). Easy to misdiagnose without pulling the washer because the leak tracks down the back panel.
Fix: Replace the failed hose with OEM, re-clamp at both ends, verify no leak under pressure.
Typical all-in: $185–$265 all-in
What it is: Slow drip from the back of the washer even when off, or a strong leak during the fill cycle. The inlet valve solenoid diaphragm has failed and weeps under line pressure.
Fix: Replace OEM inlet valve assembly. Verify both hot and cold solenoids open and close cleanly.
Typical all-in: $215–$315 all-in
What it is: Leak under the center of the washer during spin, sometimes with a rust-colored stain. The sealed tub bearing has failed and water is escaping past the seal, or the outer plastic tub has stress-cracked. Common on 10+ year top-loaders.
Fix: Pull the washer, split the tub, replace OEM seal-and-bearing kit. We quote against replacement honestly — on a 10+ year unit it sometimes doesn't pencil.
Typical all-in: $485–$785 all-in
Diagnostic order
Power off, dry the floor and the cabinet base completely with towels. You cannot trace a fresh leak through standing water.
Disconnect the supply hoses and drain line, walk the washer forward. Inspect both fill hoses at the back-panel connection for drip evidence.
With drain line in a bucket and washer pulled forward, run a fill-only cycle (30 seconds). Watch the inlet valve, hose fittings, and the bellow (front-load) for live drip evidence.
Cancel-drain the load. Watch the drain pump, the drain hose, and the tub-to-pump connection for live drips.
If fill and drain are dry, the failure is the tub seal or door bellow tear (front-load). Spin cycle is where these present. This is the expensive diagnosis — confirm before quoting.
FAQs
Door bellow, drain pump, hose, and inlet-valve repairs ($185–$385) are worth it on almost any washer under 12 years. Tub seal work over $485 on a 10+ year top-loader sometimes doesn't pencil against replacement — we give you the honest math in writing.
No — even a small leak rots subfloor, swells cabinet bases, and can cause electrical hazards. Turn off the hot and cold supply valves at the wall and don't run another cycle. Most leaks worsen by 3–5x within one more wash cycle.
Most leak repairs land $185–$385 all-in. Tub-seal work runs $485–$785 when it's worth doing. Flat $149 trip fee is credited to whatever repair you approve. We find the source first and quote in writing before any work.
Both. Front-loaders most commonly leak from the door bellow; top-loaders most commonly leak from the tub seal or drain hose. We carry OEM bellows, drain pumps, and hose kits for Whirlpool, LG, Samsung, Maytag, GE, Electrolux, Frigidaire, and Bosch on the truck.
A slow front-load bellow leak traps moisture in the rubber folds and grows mold within 2–3 weeks. Replacing the bellow solves both the leak and the smell. Don't waste money on cleaning treatments before fixing the source.
Most policies cover sudden-and-accidental water damage but not gradual leaks left unrepaired. We give you a written diagnostic report and itemized invoice that supports a claim if you need one. Stop running the washer the moment you see water.
