The short answer
Water appearing where it should not on the Alpicool CX family points first at a blocked defrost drain. That is not where the brand-generic article on this symptom starts, so a reader arriving from it should expect a different order here. The first checks below need no tools and no panel off, and they remove most of this list between them.
What you observe
- Clean cold water at the back of the unit — Supply water arrives whether or not the unit has run.
- Water arrives after the unit was moved — A pan off its seat or a fitting disturbed both date to the move.
- A pool under the front of the unit — Water reaching the floor at the door is usually meltwater that missed its drain.
- The floor is wet only in humid weather — Condensation rather than plumbing, and it is fixed at the seal.
- Beads of water on the outside of the door — Warm room, cold surface, and no fault at all.
- A CX unit of a different size behaves identically — That is what a shared build looks like: the members of this ladder differ in scale rather than in arrangement.
- 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 CX family
- A blocked defrost drain — It is where this family starts. Meltwater that cannot reach the tray backs up and comes out at the lowest edge it can find.
- A fill valve that is seeping — Second on this family. The water appears at the back rather than under the door, which places it before anything is opened.
- A cabinet that is not sitting level — Third. It is corrected with the feet rather than with a part, which makes it worth checking early.
- 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: This family keeps the brand-generic lead, but the order behind it is not the brand's. A fill valve that is seeping has moved up into second place, ahead of a door seal letting warm air in, and what moved it is the shape of this family's numbering rather than anything about the brand as a whole.
Check in this order, and why
- Look for standing water at the lowest inside edge — A drain that cannot take water leaves it where it was made.
- Look for a trickle at the back that never pauses — A valve that no longer seats passes water between fills and leaves a pool with no obvious source.
- Check which corner is damp — Water goes to the low corner, so the damp patch is telling you where the tilt is.
- Decide whether every drain, seal, pan and line has been proved good — Water tracking inside the cabinet wall is what is left after all of them.
- Body: One order serves the whole CX ladder. The members differ in scale rather than in arrangement, so the sequence below does not need a per-model variant.
Before you open anything
Safety
Isolate the unit first. Unplug it or switch off its breaker before any panel is removed, because a capacitor can hold a charge after the power is off. Leave the door switch wired as it is: it cuts the fan when the door opens for a reason, and defeating it puts a hand near a blade that is still able to turn. 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 here is drawn at the first check that cannot be made from outside the cabinet. 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. Two things end the owner-side list immediately: a burning smell, and oil anywhere outside the tubing. Both mean stop and call rather than continue.
