The short answer
A leaking washer sorts by location: behind the machine means supply or drain, at the front means the door seal or the detergent drawer. The drain hose connection at the back is worked by vibration on every spin and eventually loosens. The seal and the drawer are owner work and need no parts to diagnose. Part numbers are left to the table above; the text stays with the method, which is what holds.
How it presents
- Water only while the machine is emptying — The drain hose, its clip, or the waste connection rather than anything in the drum.
- Damp at the back wall behind the machine — A supply fitting weeping slowly. It often shows as staining long before it shows as a puddle.
- A trickle from the bottom of the door seal — A tear or a fold in the rubber, sometimes with a coin trapped behind it that cut the seal in the first place.
- Foam escaping round the door — Too much detergent. Foam creeps past a seal that holds water without difficulty.
- A puddle that grows while the machine is idle — Supply water under pressure. Close the tap before anything else happens.
- NEAR MISS — water inside the drum that will not drain — That is a drainage fault with its own page for this family, not a leak.
The ranking for this platform
- Door seal torn, folded or holding debris — First on this roster. The seal has to flex on every cycle, it collects coins and grit at its lowest point, and a small cut at the bottom leaks only when the drum is full and turning.
- Detergent drawer overflowing — Second and frequently misread as a serious fault. Powder residue silts up the siphon and the housing, so the incoming water backs up and comes out of the front of the drawer.
- Overdosing — foam escaping past a good seal — Foam has far lower surface tension than water and creeps past seals that hold water indefinitely. The history is usually a leak that started after a change of detergent.
- Drain hose clip loose or the hose split — Water only at the drain stage, always at the back. Vibration works the clip loose over years and the hose fatigues where it bends tightest.
- Supply hose fitting or tap weeping — Mains water, so it does not stop. Least common on this list and the most damaging, which is why it gets checked early despite its rank.
- Tub seal or bearing seal leaking — Last. Water from the centre of the machine rather than any connection, usually with a rumble on spin and eventually rust-coloured marks on washing. It is a major repair on this platform.
Time it, then locate it
- Lay paper towel around the machine and run a short cycle — Front, back or underneath: the paper answers in one run what guesswork does not answer in a week.
- Fold back the door seal all the way round and look inside it — Coins, grit and tears live at the bottom of the fold, which is exactly where the water sits.
- Check the supply fittings with the machine idle — Anything wet while nothing is happening is mains water. Close the tap first and diagnose second.
Isolate first
Safety
Nothing below happens with the machine live. Unplug it or switch off its breaker, and treat any capacitor as charged until it has been discharged properly. Isolate at the breaker before removing any panel.

The line between a fix and a call
Try the dose and the drawer before calling anybody; between them they explain a large share of leaks at the front. Call when a clean, intact seal on a correctly dosed machine still leaks during the wash.
