The short answer
Leaks on the DIT 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 you observe
- A damp patch that appears only on hot programmes — On the models listed in the table on this page, steam condensing past a hardened gasket wets the door edge on long hot cycles and stays dry on short cool ones.
- Water behind the machine but a dry floor in front — Points at the fill or drain connection rather than the tub, since the base tray would have carried a tub leak forward.
- Detergent residue streaking the inside of the door — A dispenser flap or its seal is releasing early, and the resulting overflow path wets the door edge rather than the tub. The models in the table behave the same way here.
- NEAR MISS: water stands inside the tub but the floor is dry — That is a drainage fault, covered on the drainage page for this family, and nothing on this page applies to it.
Causes, most likely first
- A dirty, hardened or displaced door gasket — Ranked first on the DIT 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. That holds across every model this page covers.
- Over-foaming from the wrong detergent — Within this line, 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.
- 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 cabinet that is no longer level — A machine tipped forward sends base-tray water to the floor rather than back to the sump, which turns a trivial internal escape into a visible leak.
- A split or corroded tub seam or sump housing — Last because it is rare and because it is the one cause that ends the machine rather than starting a repair. Everything above it must be excluded first, since each imitates it perfectly once the base tray has carried the water forward.
Check in this order, and why
- 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. It is the same on all the models in the table on this page.
- Run a finger along the whole gasket — Second, because it is free and because on the DIT 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. This applies to the whole line rather than to one model.
Before you begin
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.

When to call a technician
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. The same is true of each model covered here.
