The short answer
Water at a dishwasher usually comes down to one thing: too much detergent is producing suds that escape. Next on the list: the door gasket is perished or fouled. Note whether the water is foamy or clear, and whether it arrives at fill, during the wash, or with the machine idle — those two observations do most of the work.
What you observe
- Water on the floor around or in front of the machine — Clear or foamy, and at which point in the cycle, decides this.
- The water is foamy and it comes out around the door — Suds climb; water does not.
- Water runs down the front of the door during the wash — Only the door seal leaks while the arms are running.
- A slow puddle that returns even when the machine is off — Mains pressure does not stop for a cycle ending.
- NEAR MISS — steam escaping around the door at the end — That is normal on many machines at the drying stage and is not a leak.
Causes, most likely first on this machine
- Too much detergent is producing suds that escape — First because it is free to rule out and it is right far more often than people expect. Hand-washing liquid in the dispenser, or simply too much powder for soft water, generates foam that carries out past a perfectly sound door seal.
- The door gasket is perished or fouled — Ranked here because the gasket is the fastest-ageing part on the machine and the leak it produces is intermittent by nature.
- The inlet hose or its fitting is weeping — Ranked here because it is the only water on the machine that is pressurised continuously.
- The sump or the pump seal is weeping from underneath — Last, and a service job — it means the machine out of its housing.
Check in this order, and why
- Look at whether the water on the floor is foamy — Foam is a dosing answer, not a plumbing one.
- Run a finger along the whole door gasket — A hard, flattened or fouled section is where the water is getting out.
- Dry underneath and recheck with the machine idle — Only pressurised water returns while nothing is running.
- Note whether the water comes from the middle or the door — Under the centre is the sump; at the front is the door.
What an owner can safely check
- Dry the floor and run a short cycle, watching — Note the exact moment the water appears; that is most of the diagnosis.
Tools: towelsAbout 45 min
- Run one empty cycle with no detergent at all — If it stays dry, the dose was the fault.
About 60 min
- Wipe the gasket clean and feel for hard or flattened sections — A seal that has taken a set will not recover.
Tools: clothAbout 15 min
- Dry the area, leave the machine off and recheck after some hours — If it returns, shut the supply valve and call.
Tools: towels, torchAbout 20 min
- STOP HERE before pulling the machine out or disturbing a fitting — Mains-pressure water in a cabinet full of electrics is not owner work.
Before you open anything
Safety
Switch the machine off at its spur or breaker before removing any panel, and close the isolating valve before touching a hose. A capacitor can hold a charge after the power is off. Broken glass ends up in the sump on any machine. Wear gloves to clear a filter, and shut the isolating valve before disturbing a hose.
When to call a technician
Call once the gasket, the dose and the latch are all ruled out and water still arrives, or as soon as the water is under the machine and returning while it is switched off. Mains-pressure water does not stop on its own. Call immediately if water is reaching an outlet or has run under an adjoining cabinet.

What this page does not cover
This page is written for the brand and the machine class, not for one family or model line. Where a family- or model-specific page exists for your machine, it is the more specific answer. Deliberately absent: programme charts, place settings, spray-arm and pump part identifiers and wiring colours, which differ between the freestanding and integrated families.
