The short answer
Water under a refrigerator comes from one of three places: the defrost drain, the water supply or condensation that should never have formed. On a Fulgor Milano refrigerator the order below reflects that this is an imported built in that breathes through a plinth grille and carries a cabinet panel on its door. Where you find the water tells you almost everything, so look before you move the cabinet.
What you actually observe
- Water pooling inside, under the crisper drawers — That is the defrost drain backing up rather than a supply leak, and it is the commonest version of this fault.
- The appliance is built into cabinetry with a grille at the plinth — A built in breathes through that grille alone, so its installation is part of the fault far more often than on a freestanding unit.
- NEAR MISS: water on the door front or beading on the outside — That is room humidity condensing on cold steel, not a leak, and it belongs on a different page.
The causes, most likely first on this brand
- A defrost drain that is blocked or frozen — Every defrost sends melt water down a small drain hole. Blocked, it backs up under the drawers; frozen, it builds a sheet of ice under the freezer floor. Ranked first on a Fulgor Milano refrigerator: the drain leaves this unit into cabinetry rather than into open air, so the first sign of a blockage is water somewhere else entirely.
- A door that is not sealing and is letting humid room air in — Warm air condenses on cold surfaces, and enough of it runs to the floor as water that looks exactly like a leak. Ranked second on a Fulgor Milano refrigerator: a custom cabinet panel adds weight the hinge was set up for at installation, and any drift in that setup shows at the seal first.
- The supply line, the inlet valve or the filter housing — A compression fitting that was never quite tight, a filter head that has cracked or a valve weeping under pressure puts clean water on the floor. Ranked third on a Fulgor Milano refrigerator: the supply is run through a cabinet by an installer rather than by the factory, and the joint you cannot see is the one that fails.
Check in this order, and why this order
- Find the defrost drain and confirm it is open before you look at anything else — The defrost drain is the commonest single cause of water inside any cabinet, and it is the fastest thing here to prove.
- Look at where the water actually is before moving anything — Inside under the drawers, under the freezer floor and out on the boards are three different faults.
What an owner can safely check
- Flush the drain hole through with warm water and dry the channel — A baster, never anything rigid. This is the single most productive check on this cabinet.

- Find the drain hole at the back of the fresh food compartment and flush it through — Warm water from a turkey baster clears most blockages. Do not push anything rigid into the tube.

- STOP HERE if the next step needs a meter on live terminals or a sealed panel off — That is the line where an owner check ends and a service call begins.
Before you open anything
Safety
Water and electricity share the floor behind a refrigerator, so switch the unit off at the breaker before mopping under it or pulling it out. Unplug it before removing any panel, since a capacitor can hold a charge after the power is off. The cabinet is heavy and will run away on its rollers, so get help and shut the water supply off first.
When to call a technician
Call once the drain is clear, the fittings are dry and the seal is closing and water still appears, because what is left is inside the cabinet and needs a panel off. Call at once if the water is reaching an outlet or a cable, if it is running under kitchen units, or if a fitting is weeping faster than you can dry it, and shut the supply off while you wait.

What this page does not cover
This page covers the Fulgor Milano / Vitara / Forte refrigerator as a class rather than one family or model line. Drain routing, pan shapes, filter head fitments and supply connections differ from build to build and are deliberately not here. Where a family or model page exists for your cabinet, that page is the more specific answer and the one to read first.
