A washing machine leaking during a cycle narrows down by timing and location: leaking while it fills is a supply story (hoses and connections), leaking while it washes is often the door seal or tub, and leaking while it drains is the drain path. The inspection starts at the back of the machine, because the two rubber supply hoses and their washers are the most common source — and the most catastrophic when they finally let go, since a burst supply hose runs at full house pressure until someone shuts it off. Finding a small leak here is genuinely good luck; it's the warning the big one sends ahead.
Treat it as this-week urgent, and stop running the machine until you've at least identified the area. Turn the supply valves behind the machine off between loads while it's unresolved — that one habit removes the burst-hose scenario from the table. If the floor or wall behind the machine shows long-term damp or the floor feels soft, the leak is older than the puddle suggests and deserves prompt attention for the floor's sake as much as the machine's.
The hot and cold hoses connect at the wall valves and the machine inlets with small rubber washers that harden over time. Drips at either end, corrosion on the fittings, or a hose that's bulging or well past its youth are the most common leak story — and the one with flood potential.
The big rubber boot between the door and tub folds over on itself and traps coins, hair, and grit. A tear, or debris holding the fold open, lets wash water escape at the front — usually mid-cycle, worst with high water levels and heavy loads.
Excess or non-HE detergent in an HE machine creates suds that can push out through the door seal and vents. The puddle appears with loads that used a heavy hand with detergent, and the tub shows foam long after the cycle. A leak with a soapy signature is often this, not a broken part.
Less common and more serious: the tub itself or its seals letting water out during the wash. These leaks tend to be steady, located under the machine rather than at its edges, and they don't correspond to fill or drain timing.
A drain hose worked loose from the pump or standpipe, or a pump housing crack, leaks while draining. Because draining happens at set points in the cycle, the puddle grows in pulses — a useful timing clue if you watch a cycle with a flashlight and dry paper towels placed to map it.

Hoses, washers, connection tightening, boot cleaning, and detergent correction are all owner-level and cover most leaks. Tub and tub-seal faults, pump replacements, and anything requiring the cabinet to come apart are pro jobs — as is assessing floor damage if the leak has been quiet for a while. If the machine is older and the diagnosis is a cracked tub, ask for the repair-versus-replace math in the same conversation; tub work on an old washer rarely pays.
Rubber supply hoses have a working life, not a lifetime — many plumbers and insurers suggest replacing basic rubber hoses roughly every five years or switching to braided stainless-steel hoses, which resist bursting far better. If you don't know your hoses' age, the safe assumption is that they're due; the pair is inexpensive next to one water-damage claim.
Yes — load-dependent leaks point at the door seal (more water sloshing against it) or at suds overflow from detergent doses sized for the big load. Try a normal load with measured detergent and watch. A leak that needs a big, sloshy load to escape is rarely the supply hoses, which leak on their own schedule regardless of load size.
A small amount of residual water in the fold after a cycle is normal for front-loaders, which is why the boot should be wiped and the door left ajar between loads to prevent mildew. Water on the floor outside the machine is not residual water — that's a leak, and the distinction is simply whether it stayed inside the boot or not.
Yes — they were installed together, aged together, and live in the same conditions. If one washer or hose has failed, the other is at a similar point in its life, and the labour of moving the machine is the same once. Replace them as a pair, ideally with braided stainless hoses, and write the date on a tag so the next replacement is scheduled, not discovered.
