The short answer
A water leak on an ADB dishwasher usually comes down to suds rather than a hole: the wrong detergent, or hand-wash liquid, will foam a machine until it forces water past seals that are in perfect condition. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious. The ADB listings carry a masked suffix in the spine, so the trailing characters on your rating plate will differ from the table without changing the diagnosis.
What you actually observe
- Foam pushing out around the door during the cycle — Over-sudsing, which is a detergent fault and not a seal fault.
- A damp patch that only appears at the back of the cabinet — An inlet or drain fitting rather than the machine itself.
- Water at the front of the machine under the door — A door seal or alignment problem in the great majority of cases.
- Damp dishes but no water anywhere else — NEAR MISS: that is a drying complaint, covered on the cleaning and drying page.
- Body: Where a step below depends on which ADB listing you own, the table above is the reference; nothing here is written from a model outside it.
What causes it on the ADB platform, in likelihood order
- 1. Detergent that foams — Hand-washing liquid in the dispenser, or far too much detergent, generates foam the machine was never designed to contain, and the foam carries water out past a perfectly good seal. It ranks high on ADB because with one listing the appliance is a constant, which leaves how it is used as the main variable.
- 2. The door gasket — Wipe it dry, run a cycle and watch the bottom corners. A gasket fault repeats in the same place every time. Second on ADB: it is as common as the cause above it but takes longer to prove, so it is checked afterwards.
- 3. Seals underneath the tub — A sump gasket or a pump shaft seal weeps underneath while the front of the machine stays dry, and the water usually shows at the corner of the cabinet nearest the pump.
- 4. An item deflecting the spray at the door — An intermittent leak that follows particular loads is nearly always this rather than a failing part.
The order to work in on this platform
- 1. Look through the door for foam during the wash — Suds at the door settle the question before anything is dismantled.
- 2. Dry the gasket and the floor, run a cycle and watch the bottom corners — A gasket fault shows in the same place every time and needs no tools to find.
- 3. Look for water appearing underneath rather than at the front — Splits a front-of-machine fault from an underneath one.
Before you open anything
Safety
Switch the machine off at its breaker or unplug it before touching anything inside a wet cabinet; a capacitor can hold a charge after the power is off, and a standard household branch circuit is 15 A or 20 A at 120 V. Shut the supply valve before disturbing any fitting, and never run a leaking machine to watch it leak onto a live outlet or a wooden floor. The ADB roster is a single listing, ADB1300AF**, so everything here applies to one build rather than to a range.

When to call a technician
The line is the tub. A gasket, a load, a detergent and a supply fitting are all owner checks; anything weeping from the sump, the pump or a tub penetration needs a technician, and needs one before the cabinet floor takes the damage.
