The short answer
On the BDF line the useful first question is not what is leaking but where the water lands. Front-of-door water points at the gasket and the spray path; water that creeps out from under the toe panel points at a hose fitting or a pump seal. Sorting those two apart costs nothing and saves opening a machine that did not need opening. This is a compact family, so the ranking below is drawn from how these particular machines are put together rather than from the brand at large.
What you observe on these models
- Foam rather than clear water at the sill — Suds carry over the seal at a level clear water would not reach; the leak is a symptom of the detergent, not of the door.
- Damp or lifting flooring in front of the machine — A slow leak that has been running for weeks, which usually means a fitting rather than a seal — seals fail faster and wetter.
- Water on the sill before the wash has even started — Filling past the level the tub should hold; the wash has not begun, so nothing is being thrown anywhere.
- A stain or rust line always in the same spot on the tub floor — A seam or heater-gasket weep, which is slow, repeatable and worst on full loads.
- NEAR MISS — water only when the sink is used — That is a plumbing or disposer connection leak sharing the cabinet, not a fault of the machine. Different page, different trade.
Causes, most likely first on the BDF line
- Fill or drain hose connection, or the inlet valve body — First, and the cheapest to rule out. Hose clamps relax over time, and the inlet valve body sits under mains pressure whether the machine is running or not.
- Door gasket fouled, folded or perished — Next most likely on these models. A gasket that has taken a set no longer touches the door at the corners, and the corners are exactly where the water column is deepest.
- Cracked spray arm or a loose upper-arm feed — Third — worth checking once the two above are clean. A hairline crack aims a jet at the door skin instead of into the wash pattern, so the machine leaks only while the pump is running and is dry the rest of the cycle.
Check in this order, and why
- Check the fittings behind the toe panel on a cold machine — Dry them completely, leave the machine off for an hour, and look again — only a pressurised fitting wets itself with the machine idle.
- Run a finger round the whole door gasket — Feel for a fold at the lower corners and for the greasy film that stops it sealing. Wipe it and run a short cycle before doing anything else.
- Lift both spray arms out and look through them — Spin each one by hand, check every jet is open, and look for a split along the underside where water would escape sideways.
Before you open anything
Safety
Switch the machine off at its breaker before a panel comes off or a hand goes into the sump — a capacitor can hold a charge after the power is off. Shut the supply valve under the sink before disturbing a fitting, and never wedge the door interlock to watch a wash run.

When to call a technician
Call once the door gasket, the arms and the visible fittings have been checked and the leak is still there — at that point the water is coming from inside the base and the machine has to come out of the cabinet to find it. Call immediately if the leak is fast enough to reach a floor void, if the cabinet or the floor under it has started to swell, or if you find water anywhere near the electrical connections.
