The short answer
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 Eurodesign refrigerator the place to start is how the cabinet is standing, 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 actually observe
- Water pooled under the crisper drawers — Same cause seen earlier in its path, before the water finds its way out of the cabinet.
- 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.
- NEAR MISS: water only after the door has been left open — Condensation from humid room air is not a leak.
Causes, most likely first on this brand
- 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. Ranked first on a Eurodesign refrigerator: these are built-in units fitted into a cabinet opening, where the install decides the door line, the clearance and the drain fall, and where nothing inside the machine has usually failed at all.
- 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. Where it sits here: the single most common source of refrigerator water anywhere, and it is reachable from inside the freezer on most cabinets.
- A failing door seal condensing room air — A gap at the gasket lets humid room air in. Where it sits here: more common in hot, humid months than in winter, which is a useful clue as to whether this is the cause.
- 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.
Check in this order, and why
- Start at how the cabinet is standing — 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.
What an owner can safely do
- 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.
Tools: turkey baster, warm waterAbout 30 min
- Check the drain pan under the cabinet — Unplug first, take the toe grille off and confirm the pan is intact and sitting under its hose.
Tools: screwdriver, flashlightAbout 25 min
- STOP HERE if the water is on the pressurised side — Shut the supply valve off and leave it off.
Before you open anything
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 to call a technician
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.

This page covers Eurodesign refrigerators as a class, not one family or model line. Deliberately not here: drain trough geometry, the pan part number and the inlet valve fittings, all of which differ by family.
