Trace it before you fix it
Water on the floor around a badge-import dishwasher is most often a fitting the owner made, not a component that failed. Inlet connections, the drain hose clamp and an overfilled or wrongly detergented tub account for the great majority. Find where the water is dry and where it is wet before touching anything.
What you are seeing
- Water on the floor in front of the machine after a cycle.
- Water pooling under the machine but not at the door.
- Suds escaping from the door during the wash.
- A slow drip at the supply connection under the sink.
- Water only when the sink is used, not when the machine runs.
- Not this fault: Water standing inside the tub is a drainage fault - read that page.
- Not this fault: Damp inside the door with no floor water is usually condensation.
Most likely causes, in Dencrest order
- Inlet or drain fitting not sealed properly at installation — Why ranked: First on an owner-installed machine. The signature is water under the machine at the connection end with a dry door and a dry tub front.
- Wrong detergent or too much of it, causing suds to escape — Why ranked: Second: hand dish soap in a dishwasher produces foam that pushes past the door seal. It looks like a serious leak and is cured by changing the detergent.
- Door seal displaced, torn or dirty — Why ranked: Third. Water at the front of the machine, at the bottom of the door, points here rather than to the connections.
- Drain hose clamp loose or hose split behind the machine — Why ranked: Fourth. This gives water only during the drain step, which is a very distinctive timing.
- Tub, sump or pump seal failure — Why ranked: Last, and the only cause on this list that is not owner-correctable.
What to check, in order
- Dry the floor completely, run a short cycle and watch where water first appears. — Because: Where it appears first is where it comes from, and this one observation splits the list.
- Note whether the water arrives during fill, during wash or during drain. — Because: Fill points at the inlet, wash at the door and suds, drain at the hose and its clamp.
- Look at what detergent is being used. — Because: Hand dish soap is a common and completely reversible cause of what looks like a door leak.
- Check under the sink at the supply and drain connections for damp or mineral trails. — Because: A dry trail of white residue marks a slow leak even when nothing is dripping at that moment.
Checks you can do safely
- Dry the floor and lay paper towel across the front and under the machine. — N: 1 — Tools: Paper towel — Time: quick
- Run a short cycle and check the towel at fill, wash and drain. — N: 2 — Tools: None — Time: one cycle
- Wipe the door seal along its whole length and check it is seated in its channel. — N: 3 — Tools: Cloth — Time: quick
- Check the supply and drain connections under the sink for damp and residue. — N: 4 — Tools: Torch — Time: quick
- Switch to a proper dishwasher detergent and repeat the cycle. — N: 5 — Tools: None — Time: one cycle
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water on a kitchen floor next to a powered appliance is a slip and a shock hazard - isolate and dry before you investigate. Close the water supply valve before disturbing any inlet fitting. Never run a machine that is leaking onto a wooden floor while you wait for a repair. Do not tighten a compression fitting under pressure.
When this becomes a service call
Water appears from under the machine with dry connections under the sink. The tub itself is wet at a seam or a weld. A leak continues after the detergent and the door seal have been ruled out. The floor or cabinet base has begun to swell or discolour.

What this page does not cover
This is generalized information for dishwashers carrying the Dencrest Limited name. It does not separate built-in machines from countertop units on a faucet adapter, whose connections differ entirely, and it names no model-specific seal or hose. Where a family- or model-specific page exists it supersedes this one.
