The finding, first
Most leaks on this roster are seal, overfoaming or levelling problems, and the genuinely plumbed leaks are a minority. A drip that appears only during the wash is a seal or a hose; a puddle that grows while the machine sits is a supply fitting. Establish the timing of the leak first; it narrows the list faster than anything else. One entry in the table finishes in a wildcard, which stands for a run of trim codes that behave alike here.
How it presents
- Water appearing at the front, under the door — The gasket, the door alignment or overfoaming. All three put water past the same edge.
- Foam or suds visible through the door or left in the tub — Too much detergent, the wrong detergent, or washing-up liquid in the machine. Foam climbs and escapes where water would not.
- A puddle that grows while the machine is not running — That is supply water, not wash water, and it needs the tap closed before anything else happens.
- Water only when the machine is full — Level rather than pressure. A fully loaded tub holds more water and reaches higher up the door.
- NEAR MISS — water inside the tub that will not go away — Standing water is a drainage fault, not a leak, and it has its own page for this family.
Ranked causes for these models
- Door gasket hardened, displaced or dirty — First on this roster. The gasket is a rubber part living in a hot, wet, greasy environment, and it takes a permanent set over the years so that it no longer springs back against the door.
- Overfoaming from too much or the wrong detergent — Second and the most commonly missed. Foam has a much lower surface tension than water, so it creeps past a seal that holds water perfectly, and washing-up liquid in a dishwasher will do it every time.
- Machine not level, so the door does not close square — A built-in machine sitting on an uneven floor twists slightly in its aperture, and the door then touches the gasket on one side before the other. The gap is at the top corner and the water is at the bottom.
- Inlet valve, supply fitting or tap leaking — Last by frequency and first by urgency. Mains water under pressure behind a built-in machine does not stop, and this is the cause that damages a kitchen rather than a cycle.
Time it, then locate it
- Lay paper towel across the floor and run a short cycle — Where the paper wets first tells you front or underneath, which is the split the rest of this page depends on.
- Put a level on the door and on the top edge of the tub — A twist here is what opens a gap at one corner, and it is corrected at the feet rather than with parts.
- Check the supply fitting and the tap with the machine idle — Anything wet while the machine is doing nothing is mains water. Close the tap first and diagnose second.
Safety before diagnosis
Safety
Nothing below happens with the machine live. Unplug it or switch off its breaker, and treat any capacitor as charged until it has been discharged properly.

When to call a technician
Call at once for anything wet while the machine is idle — that is mains water and it has a deadline. For the rest, the owner line is the door: cleaning or replacing a gasket, correcting the detergent and levelling the machine are all owner work, and anything requiring the tub to be opened from below is not.
