The short answer for this family
On an Alpicool refrigerator in the MT family, water appearing where it should not comes back most often to a drain trough that has iced over. The order below is this family's own, and it is not the order the brand-generic article sets out. Most of what follows can be settled without opening anything; only the last item is a service call.
What the owner sees
- Water standing inside the cabinet — A drain that cannot take water leaves it where it was made.
- Ice building under the drawers — Meltwater freezing before it drains does this.
- 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.
- More than one MT unit shows the same thing — With 2 builds under this key, the same behaviour across two of them points at the family rather than at one machine.
- NEAR MISS — water only in the ice bin — Melted and refrozen ice is a temperature story; that is the ice page.
Causes, most likely first on the MT family
- A drain trough that has iced over — It leads here. It comes back on a schedule, which is what separates it from a one-off blockage.
- Condensation on the cabinet exterior — It sits behind the lead here. It wipes off and comes straight back, which is the test that identifies it.
- A fill valve that is seeping — It is third on this family. A valve that no longer seats passes a trickle between fills and leaves a pool with no obvious source.
- A cabinet liner or sealed-system fault — Last on this family. It is the least likely cause here and the one that ends the owner-side list.
- Body: The brand-generic article on this symptom opens on a blocked defrost drain. Here it does not: a drain trough that has iced over 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
- Look upstream of the drain itself for ice in the trough — Clearing the drain alone does nothing while the trough above it is still closed.
- Decide whether the water is inside the cabinet or on it — This is the split that saves the most wasted work on this page.
- 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.
- Establish whether the water is coming from behind the liner — Nothing behind the liner is reachable from outside.
- Body: Read the plate before starting: the MT pair are one step apart, and a check aimed at the wrong member wastes the visit rather than the minute.
Before any panel comes off
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. 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
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 only item on this page that cannot be judged from outside the cabinet. 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.
