The short answer
On the DDS line the useful first question is not what is leaking but where the water lands. Front-of-door water points at the gasket and the spray path; water that creeps out from under the toe panel points at a hose fitting or a pump seal. Sorting those two apart costs nothing and saves opening a machine that did not need opening. This is a compact family, so the ranking below is drawn from how these particular machines are put together rather than from the brand at large.
What you observe on these models
- Damp or lifting flooring in front of the machine — A slow leak that has been running for weeks, which usually means a fitting rather than a seal — seals fail faster and wetter.
- Water on the sill before the wash has even started — Filling past the level the tub should hold; the wash has not begun, so nothing is being thrown anywhere.
- A stain or rust line always in the same spot on the tub floor — A seam or heater-gasket weep, which is slow, repeatable and worst on full loads.
- Water across the floor at the front of the door — A line of water along the door sill after a cycle, usually widest at one lower corner rather than evenly spread.
- NEAR MISS — water only when the sink is used — That is a plumbing or disposer connection leak sharing the cabinet, not a fault of the machine. Different page, different trade.
Causes, most likely first on the DDS line
- Door gasket fouled, folded or perished — First, and the cheapest to rule out. The gasket takes every door slam and every hot cycle, and it is the only part of the water boundary that has to move; that is why it leads the list on almost any dishwasher.
- Oversudsing or a rinse-aid dispenser leak — Next most likely on these models. A soapy leak with a clean tub and a healthy gasket is this and nothing else.
- Cracked spray arm or a loose upper-arm feed — Third — worth checking once the two above are clean. A hairline crack aims a jet at the door skin instead of into the wash pattern, so the machine leaks only while the pump is running and is dry the rest of the cycle.
Check in this order, and why
- Run a finger round the whole door gasket — Feel for a fold at the lower corners and for the greasy film that stops it sealing. Wipe it and run a short cycle before doing anything else.
- Look at what is on the floor before you mop it — Soapy water with a bubble edge is a detergent problem; clear water is a mechanical one. This costs nothing and rules out a whole branch.
- Lift both spray arms out and look through them — Spin each one by hand, check every jet is open, and look for a split along the underside where water would escape sideways.
Before you open anything
Safety
Kill the power at the breaker first: a capacitor can hold a charge after the power is off. Treat standing water as if it holds glass, scoop it out rather than feeling through it, and leave the door interlock alone — it is what keeps scalding water inside the cabinet.

When to call a technician
The line is the toe panel. In front of it — gasket, arms, detergent, loading — is owner work. Behind it, a pump seal or a cracked base means the machine comes out, the supply gets shut off, and the job needs a service call. Call the same day if water has reached an adjacent cabinet or a wooden floor, because the damage outruns the repair.
