What this usually is on DL cabinets
A DL cabinet that leaks is usually leaking its own melt rather than anything from a supply. That matters because it changes the urgency: a blocked drain is a nuisance that ruins a floor slowly, while a supply leak fills a room. Establish which you have before anything else, by finding out whether the water is cold, clean and intermittent or steady and increasing.
How the fault presents
- The gasket itself is wet along one edge — That edge is where room air is getting in, and it is where the seal test should start.
- The water appears in a cycle, a day or two apart — That rhythm is the defrost cycle, which places the fault firmly on the drain side.
- An old stain on the floor with no visible water now — An intermittent leak on the defrost cycle rather than a continuous one.
- NEAR MISS — water plus a cabinet that is no longer cold — That combination is a cooling fault with melt as its symptom, and the cooling article is the right place to start.
What it usually turns out to be, in order
- Water supply line, its connection or the fill valve — Only models plumbed for water have this cause at all, and where it exists it is the one that matters most: a supply leak is continuous rather than cyclic and it does not stop on its own. It heads the list because the two codes in this group share it — nothing in the model table separates one code from another on this point.
- Door seal letting warm damp air in — A gasket that no longer seals admits room air, and that air gives up its moisture on the first cold surface it meets. Second here, and it is the rank most sensitive to how the cabinet is used — a unit opened all day sees this far sooner than one that is not.
- Containers or packaging blocking the internal channel — The channel that carries melt to the drain runs along the back of the compartment, and a drawer pushed hard back or a box standing in the channel dams it. Third: real, but it usually announces itself with something the first two causes do not produce, so the earlier checks will have already pointed at it.
The order of checks, and why it is this one
- The order and why — Two of the causes above are settled from inside the cabinet and two need it pulled out. Doing the inside pair first avoids moving a full machine for nothing.
- If the cabinet is plumbed, dry the fitting and watch it — A fitting that is wet again within minutes is the leak. Close the shutoff before doing anything else.
- Test the seal with a strip of paper at four points — A strip that pulls out without resistance shows where the air is getting in, and that spot is usually where the water is worst.
- Empty the bottom of the cabinet and look at the channel — It should be clear along its length and slope toward the drain opening.

Safety
Power off before anything else — the plug out, or the breaker open. A capacitor can hold a charge after the power is off.

The line between a fix and a service call
Two conditions make this a service call rather than a Saturday job: the cause is behind a sealed panel, or the cause is the sealed system itself. Either way the tools are not owner tools and the refrigerant is not owner-serviceable.
