The short answer
Alpicool's NL family answers water appearing where it should not in a particular order, and a cabinet that is not sitting level is at the top of it. The brand-generic page opens elsewhere, and the ranking below says which cause moved and what moved it. The first checks below need no tools and no panel off, and they remove most of this list between them.
What you observe
- Water arrives after the unit was moved — A pan off its seat or a fitting disturbed both date to the move.
- Clean cold water at the back of the unit — Supply water arrives whether or not the unit has run.
- Water standing inside the cabinet — A drain that cannot take water leaves it where it was made.
- A trickle that never stops — A seeping valve does not pause between fills.
- Water appears on a schedule rather than at random — Anything on a schedule is following the defrost cycle.
- It matches reports from the other group of this key — The NL table has a low group and a higher one with a gap between them; a report from the far side of that gap does not always transfer.
- 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 NL 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.
- A blocked defrost drain — Second on this family. The water arrives in a pattern that follows the defrost cycle rather than the door being opened.
- A door seal letting warm air in — Third. It is a condensation story rather than a plumbing one, and it is fixed at the door.
- 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 the spread of the entries this family's model table carries.
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.
- Look for standing water at the lowest inside edge — A drain that cannot take water leaves it where it was made.
- Close the door on a sheet of paper and pull it out — Where it slides freely, warm wet air is arriving and making water faster than any drain can carry it.
- Establish whether the water is coming from behind the liner — Nothing behind the liner is reachable from outside.
- Body: Decide which NL group you are in before you start. The two clusters in the table are far enough apart that the access assumptions behind this order are not identical across them.
Before you open anything
Safety
Power off first, every time. Unplug the appliance or switch off its breaker before removing a panel, since 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. Anything on the sealed side belongs to a licensed technician. That line does not move because a fault is small or a part looks accessible.

When to call a technician
On this family the split is simple: anything reachable without removing a panel is owner work, and nothing past that is. 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. Call straight away, without working down the list, if you smell burning or see oil outside the tubing at the back: oil outside the tubing means the system is open, and every hour it runs after that costs more to put right.
