Start here
On the DWT line the door gasket and the detergent account for most reported leaks, and both are checked without a tool. The connections and the tub are behind them in likelihood and behind the kick panel in access, which is a convenient coincidence for an owner.
What owners actually see
- Water running down the outside of the door — On the models this family spans, visible during the wash rather than after it, and usually traced to the gasket sitting proud of its channel at one corner.
- A damp patch that appears only on hot programmes — 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. The same is true of each model covered here.
- 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 DWT 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. The models in the table behave the same way here.
- Over-foaming from the wrong detergent — Across the whole of 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 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 is true of every model this family spans.
- Run a finger along the whole gasket — Second, because it is free and because on the DWT 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 does not vary across the models listed on this page.
- Inspect the sump hose clips by torchlight — They are visible from the front once the kick panel is off, and a perished clip shows a white mineral trail where it has been weeping.
- Reload the machine and spin both spray arms by hand — An arm that strikes a tall item is thrown off its axis and sprays the door edge directly, which no seal will hold back.
- Check the machine is level in its housing — A cabinet leaning forward drains its base tray onto the floor rather than back into the sump, turning a trivial escape into a visible leak.
Safety first
Safety
Isolate the appliance before the kick panel comes off and mop the floor before you kneel on it. A wet floor under a built-in cabinet is the most likely injury in this whole job.

Where the owner line is
The owner boundary is the kick panel. Once a leak has been traced past it, the machine has to come out of its housing with the services disconnected, and that is service work on the DWT line. It is the same on all the models in the table on this page.
