The short answer
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 an Essentiell 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 actually observe
- Water directly beneath the door, appearing mid-cycle — Points at the door gasket or at a door that no longer closes square.
- Water at the back or under the centre of the machine — The supply or drain connections, or the sump gasket, rather than the door.
- Suds on the floor rather than clean water — Too much detergent, the wrong detergent, or washing-up liquid in the machine.
- 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.
Causes, most likely first on this brand
- 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 an Essentiell dishwasher: these are integrated kitchen machines fitted flush into a run of units, where the drain and waste path is the part the installer had least room for and the part that silts first.
- 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 weeping inlet hose, drain connection or filter head — The inlet side is pressurised whenever the household supply is on, so a loose compression nut or a perished washer weeps continuously rather than only during a cycle. Where it sits here: ranks above the door whenever the water is clean, continuous and appearing at the back rather than at the front.
Check in this order, and why
- 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.
What an owner can safely do
- Clean the door gasket and the flange it seals against — Warm soapy water on both, then dry.
Tools: cloth, mild detergentAbout 15 min
- Run a rinse cycle with no detergent at all — If the leak was foam, this clears it and the floor stays dry from then on.
About 45 min
- STOP HERE if a pressurised fitting is weeping — Shut the supply valve and leave it off.
Before you open anything
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 to call a technician
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.

What this page does not cover
This page covers Essentiell dishwashers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: gasket part numbers, hose kit references and the sump seal sets, all of which differ by family.
