Start here
A leak on the DIN line is usually the door seal or the lower door edge rather than a split hose, because these models seal the door against a one-piece gasket that sits in a channel and can be lifted out of it by a knock. Find where the water lands before anything is dismantled: front, under, or behind are three different faults.
What owners actually see
- The cabinet sides feel warm and damp during a wash — Across the whole of this line, steam escaping past the seal rather than liquid water, which points at the gasket seating instead of a split hose.
- Water only appears on full loads — A load-dependent leak points at spray deflection or at foam height rather than at a connection, which leaks regardless of what is inside.
- Suds are visible through the door window during the wash — Foam above the door line names the detergent as the cause and removes the hardware branch entirely. 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 DIN 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.
- A loose or perished hose clip at the sump — The sump connections sit under the tub where the base tray catches any escape and carries it forward, which is why a rear leak so often shows at the front foot.
- 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 holds across every model this page covers.
- Run a finger along the whole gasket — Second, because it is free and because on the DIN 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.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing the kick panel. A capacitor can hold a charge after the power is off. Water and electricity share the base of this cabinet, so dry the tray before working in it and never reach behind a panel while the machine is connected.

Where the owner line is
Call when the gasket, the detergent, the loading and the visible connections are all clear and the base tray still fills. That points at the tub or the sump housing on the DIN line, which needs the machine out of its housing and the water services disconnected. It does not vary across the models listed on this page.
