The short answer
On a Cafe integrated dishwasher the likeliest sources are the door gasket, over-dosed detergent and the supply or drain connections, in that order. Dry everything, run one cycle and find which phase puts water down. Stop using the machine until you know, because the cabinetry absorbs what you cannot see.
What you observe
- A swollen plinth or cabinet base near the machine — The classic late-discovered integrated leak.
- Water at the door bottom during the wash — A gasket leak spills at the lowest point of the opening.
- Suds escaping the door — Over-dosing, which pushes foam past the seal.
- Water only while it drains — A drain hose or clamp leaking under pump pressure.
- NEAR MISS - a damp cabinet after a supply valve was worked on — A connection disturbed, not the machine.
Causes, most likely first on this brand
- A fouled or damaged door gasket — First on any dishwasher. Debris in the seal, or a split at the bottom corner, lets water escape while the arms are spraying, and the custom panel hides the trickle from view.
- Detergent overdosing or the wrong product — Second, and easy to dismiss. Excess foam finds the shortest way out, and hand-washing liquid in a dishwasher floods a kitchen very effectively.
- A supply or drain connection weeping — Third. Both are behind the machine, both are disturbed whenever anything is worked on under the sink, and a weep produces exactly this slow cabinetry damage.
- A door not closing squarely under panel weight — Fourth, and specific to panel-ready machines. A heavy custom front can pull the door out of line so the gasket cannot seal evenly.
- A sump, hose or tub fault inside the machine — Last. Not an owner check, and it means drawing the machine out of its run.
Check in this order, and why
- Stop using it until the source is known — Every extra cycle adds water to a cabinet you cannot see.
- Dry everything and run one cycle with a torch — Watching the leak start answers it in one cycle.
- Wipe right around the door gasket — Debris and splits are both found by hand.
- Halve the detergent and repeat the same load — If the leak goes, it was foam and not a fault.
What an owner can safely check
- Stop using the machine and dry the cabinetry — Lay paper towel under the plinth so a new leak shows itself.
Tools: paper towel, torchAbout 25 min
- Clean and inspect the door gasket — Open the seal all the way round, clear debris and look for splits at the corners.
Tools: clothAbout 20 min
- Use the correct detergent at a lower dose — Never hand-washing liquid, and less than you think for a soft-water area.
About 10 min
- Check the door closes squarely — Look for an uneven gap along the seal under the weight of the panel.
Tools: torchAbout 15 min
- STOP HERE if water comes from under the machine with a clean gasket — That means drawing it out.
Before you open anything
Safety
Switch the dishwasher off at its breaker and close its supply valve before investigating a leak - you are working with water beside an electrical appliance in an enclosed cabinet. Never run another cycle to see whether it leaks again once you know it does. If the machine trips a breaker or a residual current device, leave it off and call, because water has already reached something electrical.
When to call a technician
Call when the gasket is clean and sound, the detergent is correct and dosed low, the door closes squarely and water still reaches the cabinetry. Call immediately, with the supply valve closed, for a leak you cannot stop or any leak that trips the electrical protection. Say that the machine is integrated when you book, since cabinetry and a custom panel both affect access.
