The short answer
Note when the water appears. During fill means supply hoses or the inlet valve; during spin means the bellows, the drain hose or the tub seal; after the cycle means drainage or a pump housing. Supply-side leaks are the urgent ones because they run at building pressure with nobody watching.
Timing tells you the branch
- Water appears as the machine fills — Supply connections or the inlet valve.
- Water appears during the spin only — Bellows, drain hose or a tub seal under pressure.
- Water is present after the cycle ends — Drain path or the pump housing.
- A slow drip behind the machine at all times — A supply fitting under constant pressure; treat as urgent.
- Suds escaping rather than water — Overdosing, and it is the easiest one to fix.
- Not this fault: standing water inside the drum — That is the drainage page.
Ranked for a commercial installation
- Supply hose or its connection weeping — First by risk and common by frequency, because the supply is always live.
- Bellows torn or held open by debris — Second, and it shows during the spin when water is thrown outward.
- Drain hose connection loose or split — Third, and often disturbed when a machine is pulled out for cleaning.
- Pump housing or filter cover not sealed after cleaning — Fourth, and entirely self-inflicted; always test after a filter clean.
- Excess detergent causing suds to escape — Fifth, and a dosing problem rather than a mechanical one.
- Tub seal failing — Last, and the only cause here that is a major repair.
How to find it
- Close the supply taps and see whether a standing drip stops — It separates supply-side from everything else immediately.
- Dry the floor completely and run a short cycle while watching — Timing is the diagnosis on this page.
- Check the filter cover and its seal if the machine was recently cleaned — This is the most common self-inflicted leak.
- Inspect the bellows fold last, with the door open and the seal pulled back — It is the most likely drum-side source.
Site-side checks
- Close both supply taps and dry the area thoroughly — Stops the most dangerous leak class while you investigate.
Tools: towelsAbout 15 min
- Run a short cycle and watch each stage from a safe distance — Fill, wash, spin and drain each implicate different parts.
About 45 min
- Re-seat the drain filter cover and confirm its seal is clean — A poorly seated cover leaks exactly as a pump failure does.
Tools: glovesAbout 15 min
- Pull back the bellows fold and check for tears and trapped items — The most common drum-side cause and easy to see.
Tools: torch, glovesAbout 15 min
- Reduce the detergent dose and re-run if suds are escaping — It costs nothing and rules out the easiest cause.
About 45 min
- Stop before removing the pump, the tub or any internal hose — Those are service parts on a machine that holds hot water.

Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never work on a machine standing in water; dry the floor first and treat any wet electrical connection as live until it is isolated. Close both supply taps before disturbing a hose, and remember that the water inside a machine mid-cycle is hot.
When to call
Call immediately for any weeping supply connection, because that is the failure mode that floods a building overnight. Call for a torn bellows, for a leak that appears only under spin once the filter cover has been checked, and for any leak whose source you cannot see. On a commercial site, take the machine out of service while you wait rather than running it between inspections.

Page scope
Generalized across the Professional washer range and not written for one model line. Where a family-specific or model-specific page exists it is the narrower answer. Deliberately absent: hose specifications, seal part numbers, pump housing details and the plumbing arrangements that vary from site to site.
