The short answer
Leaks on the Cafe CDT family divide by timing. Water that appears during the fill is an inlet fitting or valve; water that appears at the end of a wash is the door, the seal or suds; water present at any time is a sump or a hose. The matrix below spans seven model tags across more than one prefix group, so running changes are real here and the tag decides which revision of a part a model takes. Timing is evidence and costs nothing to collect.
What you can observe on these models
- A leak that appears during the fill only — That is the inlet side: the fill hose connection, the inlet valve body or the fitting at the shutoff.
- Water appears when the door is opened mid-cycle — Normal carry-over from the door panel, not a leak. Let a cycle finish before judging.
- The door does not sit flush with the cabinet front — A hinge or spring out of adjustment loads the seal unevenly, so it leaks at one corner only.
- Water tracking down the inside of the door panel — The vent or the detergent dispenser area is spilling, which points at suds or at a blocked vent rather than the tub seal.
- NEAR MISS — standing water inside the tub with a dry floor — That is a drainage fault, not a leak, and the drainage page covers it.
Causes, most likely first on this family
- Supply-side fitting, fill hose or inlet valve — Ranked first because closing the shutoff stops it immediately and confirms the diagnosis at the same time.
- Sump seal, pump housing or hose clamps — Second: heat and pressure open a marginal seal, which is why these leaks show on long cycles and not on short ones.
- Door gasket and its seating — Third because the symptom location already argues against it when the floor is wet at the sides.
- Detergent foam escaping the vent or the seal — Fourth: check what went in the dispenser before condemning any part, particularly after a change of product.
- Levelling and floor slope — Last, and corrected with a level and the feet.
Check in this order, and why
- Note where the water is and when it appears — Front-of-door at the end of a wash, under the cabinet at any time, or during the fill only — three different lists, no overlap.
- Run a hand around the door gasket — Feel for hard spots, tears and debris in the channel. Anything that breaks the contact line leaks at exactly that point.
- Run one load with a correct dishwasher detergent — Removes suds from the picture entirely, which is worth doing before any part is suspected.
- Dry the floor and lay paper towel along the toe kick — It shows whether the water comes forward from the door or sideways from under the cabinet.
Before you open anything
Safety
Kill the power and close the supply before any fitting is disturbed — a capacitor can hold a charge after the power is off. The fill line stays pressurised until it is bled, so open it into a towel and expect the residue in the hose to be hot after a recent cycle.

When to call a technician
Correcting the detergent, cleaning and reseating a gasket, levelling and checking the door alignment are owner jobs on the Cafe CDT family. Call the moment the leak is on the supply side — a weeping inlet valve or fill fitting is mains pressure behind a cabinet, and it does not wait. Call also when the water comes from under the tub rather than the door, because that means the machine has to come out.
