Start here
Water on the floor in front of a refrigerator usually started inside it, and the two usual sources are the defrost drain and the supply line. Which one it is can be settled by where the water shows up and whether it is clean or not. On a Eurodib refrigerator the place to start is the defrost drain, because a built-in European cabinet carries a sensing and control layer between the owner and the compressor, so a sensor or a setting explains the symptom far more often than a failed part does.
What you are looking at
- A wet patch at the back or under the cabinet — Points at the drain pan or at the supply connection rather than at the drain trough.
- Ice building at the bottom of the freezer — The drain has frozen shut rather than silted up.
- A puddle at the front, appearing every day or two — Classic blocked defrost drain: melt water overflows the internal tray and runs forward under the liner.
- NEAR MISS: water only after the door has been left open — Condensation from humid room air is not a leak.
What it usually is, in order of likelihood
- A blocked or frozen defrost drain — Every frost-free cabinet melts its evaporator on a schedule and sends the water down a small trough to a pan by the compressor. Ranked first on a Eurodib refrigerator: this is commercially derived equipment run on domestic duty cycles, so the wear parts reach the end of their life on a schedule the rest of the machine does not follow.
- A leaking supply line, filter head or inlet valve — Any cabinet plumbed for ice or a dispenser has a pressurised line behind it. Where it sits here: ranks above the drain whenever the water is clean, continuous and pooling at the back rather than at the front.
- The cabinet is tilted forward or standing unevenly — Cabinets are meant to sit very slightly back so doors close themselves and internal water runs toward its drain. Where it sits here: cheap to rule out and easily disturbed by a move or a new floor, which is why it is worth a minute early.
- A cracked drain pan or a displaced drain hose — The pan under the cabinet is meant to evaporate the water the defrost cycle produces. Where it sits here: less common than the drain blockage but easy to confirm, since the evidence is always at the back.
The order to work in
- Start at the defrost drain — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Say whether the water is clean or not — Clean and continuous points to the supply line; cloudy, intermittent and at the front points to the defrost drain.
- Look under the crisper drawers before anything else — Water standing there confirms the defrost drain and tells you the cabinet has been doing it a while.
Owner-side checks, step by step
- Re-level the cabinet with a slight backward tilt — Wind the front feet down until a door left half open swings itself shut.

- Clear the defrost drain from inside the freezer — Find the trough at the base of the rear panel, clear it with warm water from a turkey baster and finish with a short length of soft tubing.

- STOP HERE if the water is on the pressurised side — Shut the supply valve off and leave it off.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Water and an energised appliance on the same floor is the one combination worth taking seriously here, so deal with the puddle before you deal with the cabinet. Shut the water supply off before touching any fitting, and never clear a drain with a metal probe, because the tubing behind it is thin.
When this becomes a service call
Call when the drain has been cleared and the water comes back, when the leak is on the pressurised supply side, or when you find water inside the cabinet insulation rather than on its surfaces. A slow leak into the foam does structural damage that a fast leak on a tiled floor does not, and it is the one version of this fault that should not wait.

The limits of this page
This page covers Eurodib refrigerators as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: drain trough geometry, the pan part number and the inlet valve fittings, all of which differ by family.
