The short answer
On the BSW line the timing of the leak names the fault. Water present before a cycle starts is an inlet hose or a tap. Water only during fill is the inlet valve. Water during wash is the door seal or the tub; water during drain is the pump or the drain hose. Noting when it happens saves opening the wrong panel. 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
- Water running down the front of the detergent drawer — A blocked drawer or siphon that has overflowed rather than a leak in any component.
- A damp patch under the machine that comes and goes — A slow leak from a filter cap or a hose clip, which wets the base tray and only reaches the floor once it has filled.
- Suds escaping rather than clear water — Too much detergent for the load and the water hardness, which pushes foam past seals that hold water perfectly well.
- Water on the floor before the machine has run — Only the inlet side is pressurised when the machine is idle, so this is a tap, a hose or a connection.
- Water appearing at the front during the wash — The door seal, where grit or a torn section stops it holding against the drum.
- NEAR MISS — water only when a nearby sink is used — That is a plumbing leak sharing the space, not a fault in the machine.
Causes, most likely first on the BSW line
- Inlet hose, tap or valve connection — The leading cause on this platform. Inlet hoses age, and the washer nearest the tap is the one that hardens and weeps first.
- Detergent drawer or siphon blocked — Close behind it. It is the easiest of all the causes to eliminate — the drawer pulls out and washes in a sink.
- Door seal torn or fouled — Third in order, and the one most often missed. Grit, coins and detergent residue collect in the lower fold of the seal and hold it a fraction open against the drum.
Check in this order, and why
- Dry the tap and hose connections and leave the machine idle — Come back in an hour. Only the inlet side is pressurised at rest, so any water there with the machine off is conclusive.
- Pull the detergent drawer out and wash it — Clear the siphon cap and the housing above it. A drawer that cannot siphon overflows down the front and reads as a serious leak.
- Run a hand round the whole door seal, especially the lower fold — Pull the fold open and look for grit, coins and tears. Clean it, then run a short cycle and watch the same spot.
Before you open anything
Safety
Switch off at the breaker or pull the plug first; a capacitor can hold a charge after the power is off. Shut the taps before touching an inlet hose — a hose released under pressure empties a house line into a room in seconds. Open the pump filter over a tray, and handle what comes out carefully: wires and glass chips collect there.

When to call a technician
The line on the BSW line is the cabinet. Connections, seals, the drawer and the filter cap are yours. A leak from inside — tub seam, pump housing, bellows — is a service call and the machine has to come out. Shut the taps and stop using it in the meantime, because every further cycle puts more water under the floor.
