What this usually means
On the Aviva ADBI dishwasher line, leaks that follow a cycle and leaks that are there all the time are different faults. A constant drip is a supply-side fitting under mains pressure; a leak that appears only during a wash is the door, the tub or the drain path. What changes against the brand-generic answer is the order of the checks, not the list of causes.
The observations that matter on a ADBI unit
- A slow drip behind the machine that never stops — Supply side, under mains pressure, and it is there whether the appliance runs or not. This is what an owner of a ADBI dishwasher sees first.
- Foam escaping around the door during the cycle — Overfoaming rather than a seal failure, and the cause is in the dispenser rather than in the appliance.
- Water only on one side of the machine — Useful: it points at a specific hose run rather than at the door, which leaks centrally.
- The leak appeared the week something else was fitted nearby — A waste connection or a supply tee disturbed during other work is a common origin.
- NEAR MISS: water is coming from the sink waste rather than the appliance — Worth eliminating first, because a shared cabinet hides which of the two is wet.
What it usually turns out to be on the ADBI line
- A tired or dirty door gasket — Ranked first because it is both the most common and the easiest to confirm: grease and food residue on the seal stop it compressing, and the leak shows at the front centre of the door. The ADBI build does not move this one: its rank is the same here as on the brand-generic page.
- Overfoaming from the wrong detergent or too much of it — Second, and the one that is almost never suspected. Washing-up liquid in the dispenser will put foam on the floor from an appliance with nothing wrong with it.
- A loose hose clip or a perished hose behind the machine — Third. Clips loosen over years of heat cycling, and the hose run gets crushed when the machine is pushed back into its housing.
- A split tub or a failed pump seal — Last, because it is the least likely and the only one that is not owner-checkable. It is diagnosed once everything above is clean.
The order that narrows it
- Establish whether the water is clean or soapy — Clean water is the fill side; soapy water has been through the wash. One touch, and half the list goes. The ADBI layout is the reason it comes first here.
- Watch a cycle through the glass or listen at the door for foam — Foam escaping is an entirely different fault from water escaping, and the fix is in the dispenser.
- Check the hose clips at the inlet and the drain connections — Hand-snug, and look for the white mineral trail that a slow leak leaves behind.
- Look for standing water in the tub before the cycle starts — A drainage fault forcing water out elsewhere is a real cause of a floor leak.
Before you open anything
Safety
Isolate the appliance and dry the floor before starting. Put towels down before a hose is disconnected: a drain hose holds water along its whole length and empties the moment it is freed.

Where the owner side ends
Stop and call when the leak is clean water and constant: that is mains pressure behind it, and a weeping inlet valve does not improve on its own. Shut the supply valve while you wait.
