The short answer
On a Brisas the water is melted frost. Check the drain hole at the back of the cabinet first, then the door seal, then the drip tray behind. A defrost done without towels in place accounts for a lot of one-off floods. There is no supply line here, so no valve can be leaking.
What you observe
- Water on the shelf directly under the chiller box — Melt running off the box instead of into the gutter.
- Standing water in the bottom of the cabinet — The drain hole is blocked and the cabinet is filling.
- A trickle out of the door onto the floor — Water that has overrun the cabinet interior.
- Water at the back of the cabinet only — A displaced or overfull tray above the compressor.
- NEAR MISS - drips off the box on a warm day — Normal melting. It needs a clear drain, not a repair.
Causes, most likely first on this brand
- A blocked drain hole at the back of the cabinet — First. It is a very small opening, and crumbs, a spill or a little mould close it completely, after which every drop of melt stays in the cabinet.
- A door seal admitting humid room air — Second. Warm damp air condenses and frosts heavily, so the drain is asked to carry far more water than the design intended and begins to overflow.
- A manual defrost with nothing to catch the melt — Third, and self-inflicted. A block of ice becomes a surprising amount of water, and most of it arrives at once.
- A drip tray displaced or overfull — Fourth. The tray above the compressor evaporates the melt, and knocked out of place it simply pours onto the floor at the back.
- A cabinet that is not level — Last of the ordinary causes. The gutter and the tray both rely on gravity, so a cabinet leaning forward holds water inside.
Check in this order, and why
- Find the drain hole at the back of the cabinet floor — Standing water or a plug of ice around it is the answer.
- Pour a little warm water into the gutter — It should disappear. If it sits, the drain is blocked.
- Test the door seal on a slip of paper — A seal that does not drag is making the water you are mopping.
- Look behind for the tray above the compressor — Displaced or overfull explains water at the back only.
What an owner can safely check
- Defrost the cabinet with towels in place — Lay towels on every shelf and on the floor before you start; a block of ice makes a lot of water.
Tools: towels, cool boxAbout 180 min
- Clear the drain hole — Flush it with warm water and clear the passage gently with a soft flexible probe, never a sharp tool.
Tools: warm water, soft probeAbout 20 min
- Clean and test the door seal — Wash the fold and check the paper drag at several points round the door.
Tools: cloth, paperAbout 20 min
- Level the cabinet and reseat the drip tray — Set it a shade back-low so the gutter drains, and push the tray home.
Tools: spirit levelAbout 20 min
- STOP HERE if a clear drain and a good seal still leak — That points at the gutter or the tube.
Before you open anything
Safety
Unplug the refrigerator before defrosting, clearing the drain or reaching behind it - you are working with water beside an appliance. Never clear the drain with a knife, a skewer or stiff wire, because the cooling circuit runs close behind that panel and a puncture ends the appliance. Mop the floor promptly, since water under a small cabinet reaches the compressor area and the flooring underneath it.
When to call a technician
Call when the drain runs clear, the seal drags on paper, the cabinet is level and the tray is seated, and water still appears. That points at a cracked gutter or a split tube. Call sooner if water is reaching the compressor area at the back, or if the appliance trips a breaker or a residual current device, because at that point it is an electrical matter rather than a plumbing one.

What this page does not cover
This page covers the Brisas compact single-door mini refrigerators, which have no water supply connection and defrost manually. Plumbed cabinets with an ice maker or a dispenser leak from lines and valves instead. Not included by design: drain and tray part identifiers, tube dimensions and cabinet specifications, which differ by family.
