Start here
Water on the kitchen floor from a dishwasher comes from one of four places: the door, the plumbing connections, the tub itself or the foam pushed out by too much detergent. Where the water shows up decides which, and it is worth settling that before anything comes apart. On a Finlux dishwasher the place to start is the detergent and the foam it makes, because an integrated machine will not proceed until its own sensing says it may, so the control and sensing chain outranks the pump.
What you are looking at
- Suds on the floor rather than clean water — Too much detergent, the wrong detergent, or washing-up liquid in the machine.
- A damp cabinet side or a swollen kickboard — A slow leak that has been running for a while.
- Water directly beneath the door, appearing mid-cycle — Points at the door gasket or at a door that no longer closes square.
- NEAR MISS: water standing inside the tub at the end — That is a drainage fault, not a leak, and it belongs on its own page.
What it usually is, in order of likelihood
- Too much detergent or the wrong kind entirely — Washing-up liquid in a dishwasher produces a volume of foam the machine was never designed to contain, and it pushes water straight past the door seal. Ranked first on a Finlux dishwasher: these machines run a programme that will not advance until its own checks pass, so what has been asked of the machine matters as much as what is wrong with it.
- A failed door gasket or a door that is not closing square — The gasket takes a set over years, hardens, and stops meeting the tub flange evenly. Where it sits here: the most common leak on any front-opening machine, and the one whose evidence is easiest to read on the floor.
- The machine is not level or has shifted in its opening — A machine tilted forward sends its water toward the door rather than toward the sump, and one that has been pushed in hard enough to crush its hoses leaks at the back. Where it sits here: worth a minute early, especially on a machine that has leaked since the day it went in.
- A failed sump gasket, heater seal or a cracked tub — The seals around the sump, the heater and the pump all perish with heat and age. Where it sits here: last on the list because it is the least common, and because confirming it means the machine comes out and goes on its back.
The order to work in
- Start at the detergent and the foam it makes — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Dry the floor completely and run a short cycle while watching — Where the first drop appears is worth more than every other clue on this page put together.
- Look for suds before looking for parts — Foam on the floor is a detergent fault and it has nothing to do with the machine.
Owner-side checks, step by step
- Re-level the machine in its housing — Adjust the feet until the tub is level side to side and sits a hair back, and check the door closes with even pressure along its whole length.
Tools: adjustable spanner, levelAbout 30 min
- Clean the door gasket and the flange it seals against — Warm soapy water on both, then dry.
Tools: cloth, mild detergentAbout 15 min
- STOP HERE if a pressurised fitting is weeping — Shut the supply valve and leave it off.
Safety first
Safety
Switch the machine off at the wall or its breaker before working on it; a capacitor can hold a charge after the power is off, and water on the floor plus a live appliance is the one combination genuinely worth respecting here. Shut the water supply off before touching any fitting, and remember mid-cycle water is hot enough to scald. Never run the machine with a known leak to see how bad it gets.
When this becomes a service call
Call when the door gasket and the connections are proven good and the machine still leaks, when you find water in the cabinet base or the floor rather than on it, or when the leak is on the pressurised supply side. A slow leak into a cabinet carcass does damage out of all proportion to the repair, and it is the version of this fault that should not wait.
