The short answer
On an Alpicool refrigerator in the DD family, water appearing where it should not comes back most often to a cabinet that is not sitting level. The order below is this family's own, and it is not the order the brand-generic article sets out. The first checks below need no tools and no panel off, and they remove most of this list between them.
What you observe
- The floor is wet only in humid weather — Condensation rather than plumbing, and it is fixed at the seal.
- Clean cold water at the back of the unit — Supply water arrives whether or not the unit has run.
- Water appears on a schedule rather than at random — Anything on a schedule is following the defrost cycle.
- Beads of water on the outside of the door — Warm room, cold surface, and no fault at all.
- Water arrives after the unit was moved — A pan off its seat or a fitting disturbed both date to the move.
- No second DD unit to compare against — One model carries this key, so there is nothing in the family to cross-check — the observations below stand on their own.
- NEAR MISS — the cabinet is also warm — Warm and wet together is a cooling fault first; the water is a consequence.
Causes, most likely first on the DD family
- A cabinet that is not sitting level — It is where this family starts. Meltwater that should run back runs forward instead, and the drain never sees it.
- Condensation on the cabinet exterior — Second on this family. It is worth naming because it accounts for a real share of reported leaks.
- A blocked defrost drain — Third. It is the cause that explains water inside the cabinet as well as water on the floor.
- A cabinet liner or sealed-system fault — Ranked last. Water tracking from inside the wall of the cabinet is not something an owner can reach.
- Body: The brand-generic article on this symptom opens on a blocked defrost drain. Here it does not: a cabinet that is not sitting level has moved above it, and a blocked defrost drain has moved down the list. What moved it is what this page's model table shows about how many builds sit under this key.
Check in this order, and why
- Put a level on the top and check the feet — A small tilt sends meltwater forward instead of back, and the drain never sees it.
- Decide whether the water is inside the cabinet or on it — This is the split that saves the most wasted work on this page.
- Check whether the water arrives on a schedule or at random — Water that follows the defrost cycle rather than the door is meltwater that cannot get away.
- Establish whether the water is coming from behind the liner — Nothing behind the liner is reachable from outside.
- Body: Because the DD key covers one model, the order below skips the identification step that a multi-model family needs and goes straight to the likeliest cause.
Before you open anything
Safety
Before a panel comes off, isolate the unit at the plug or at the breaker. A capacitor can hold a charge after the power is off. Do not tape or bridge the door switch to keep a fan running while you look. An interlock that is defeated is a blade that turns while a hand is in the cabinet. Refrigerant work is licensed work: nothing on the sealed side of this machine is owner work, whatever the symptom looks like from the front.

When to call a technician
The line on these models is the point where a check needs a panel off or a tool you do not keep. Work down the checks above first; they cost minutes and they remove most of this list. Call once they have all come back clean, because what is left is a cabinet liner or sealed-system fault, and that is the one cause here with no owner-side check at all. Skip the rest of the list and call if the unit is tripping protection repeatedly. A circuit that keeps opening is telling you something the checks above cannot.
