Start here
Leaks on the BDFB line divide into ones you can see and ones the base tray hides. The tray channels any escaping water toward the front foot, which is why the puddle position is evidence about where the water goes and only weak evidence about where it came from. Work the sources in order of likelihood, not in order of where the floor is wet.
What owners actually see
- Suds are visible through the door window during the wash — Across the whole of this line, foam above the door line names the detergent as the cause and removes the hardware branch entirely.
- The gasket is shiny and hard at the bottom corners — Heat and grease harden the seal fastest where water sits, so the corners fail before the top edge does.
- The machine has been moved or re-levelled recently — A cabinet leaning forward drains its base tray onto the floor instead of back toward the sump. This applies to the whole line rather than to one model.
- NEAR MISS: the machine is silent and never fills — A no-start or fill fault, which the will-not-start page for this family covers.
Ranked causes on this line
- A dirty, hardened or displaced door gasket — Ranked first on the BDFB line because the gasket is a single moulded strip held in a channel: grease hardens it, a knock lifts a corner, and either one breaks the seal along the whole edge rather than at a point. Every model in this family behaves this way.
- Over-foaming from the wrong detergent — On the models this family spans, hand dish soap or too much rinse aid raises foam above the door line and it escapes at the weakest point. It reads as a hardware fault and is entirely consumable-related.
- An overloaded or badly loaded lower rack — A tall item deflecting the upper spray arm can throw water directly at the door edge, which defeats a gasket that is in perfect condition.
- A rinse-aid reservoir overfilled or leaking — Excess rinse aid enters the wash and raises foam, which escapes at the door line and produces a convincing gasket leak with a perfect gasket.
- A failed door hinge or latch geometry — Last because it is uncommon and because it needs measurement rather than inspection: a door that closes and locks can still be sitting a fraction proud along one edge, and confirming that is service work on this platform.
The diagnostic order
- Establish where the water lands before anything else — Dry the floor, lay paper at the front foot, at each side and behind, and run a short programme. This single step splits the fault tree in three. That holds across every model this page covers.
- Run a finger along the whole gasket — Second, because it is free and because on the BDFB line a hardened or lifted section is felt long before it is seen. Clean it with hot water and check it seats in its channel all round.
- Review the detergent and the rinse-aid setting — Third, because over-foaming produces a convincing door leak with nothing wrong. Run one cycle with the correct product and a normal dose before suspecting hardware. It is the same on all the models in the table on this page.
- Look for mineral trails at every visible joint — A white deposit marks a slow weep and names the joint precisely, which no amount of running the machine will do as clearly.
Safety first
Safety
Power the appliance down at the breaker first. If the leak has reached a socket, a floor void or an adjoining cabinet, stop and treat it as an electrical hazard rather than a plumbing one, and do not restore power to check.

Where the owner line is
Stop and call if the leak has run under flooring or into an adjoining cabinet, if the appliance trips its breaker, or if you can see a wet trail from the tub seam itself. Continuing to run the machine in those cases turns a repair into damage. It does not vary across the models listed on this page.
