The short answer
Before anything else, establish where the water is: inside the cabinet, on the floor at the front, or on the floor at the back. On the Avanti WBC models covered here those three locations point at three different causes, and confusing them is what turns a ten-minute fix into a service call.
What you observe on these models
- Water inside the cabinet, at the bottom — Condensate that could not leave.
- Water on the floor at the front — Either the cabinet is leaning forward or the water came over an interior lip.
- Water on the floor at the back — That is the machine bay and the pan in it.
- Beads or runs on the outside of the door — Room humidity condensing on a cold surface.
- NEAR MISS — oily fluid at the machine bay — That is not water.
Causes, most likely first on WBC
- Condensation at the door — A door that no longer seals condenses room moisture on the cold face and drips. The tell is water that is worst along one edge and after a humid day. Ranked first on a wine cabinet: a big glass panel in a warm room is a condensing surface before it is anything else. It leads the list on Avanti WBC because these are wine cabinets — a wine and beverage cabinet concentrates this fault in a way a full-size machine does not.
- The evaporation pan in the machine bay — The pan under the cabinet is meant to evaporate what the drain delivers. If it is cracked, displaced or being fed faster than it can evaporate, the water lands on the floor at the back.
- A blocked defrost drain — This is the leak that looks worst and costs least. Melt water backs up over the drain lip and runs forward, so the water appears inside the cabinet or on the floor at the front.
- Ice melting after a warm spell or a power cut — A one-off pool after the machine has been off, or after a door was left open, is meltwater and not a fault. It matters because it is the one leak that needs no repair.
- The cabinet is not level — A cabinet leaning forward sends its drain water the wrong way. This converts a machine that was working into one that leaks, with no part having failed at all. Last on this list, and the item that every cause above it can imitate exactly.
Check in this order, and why that order
- Map the water before touching anything — Dry everything, put paper towel at the front, the back and inside the base, and come back in a day. Knowing where it arrives eliminates most of the list.
- Put a level on the cabinet, front to back — A cabinet leaning the wrong way defeats a drain that is otherwise perfectly clear. This is the cheapest cause and the most frequently skipped check.
- Inspect the pan in the machine bay — Cracked, displaced after a move, or simply full. On a cabinet of this size the pan can usually be lifted out and looked at.
- Check the door seal all the way round — Condensation follows a bad seal, and a seal that produces ice in winter produces water in summer. Same fault, different season.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the machine bay — water and mains wiring share that space. A capacitor can hold a charge after the power is off. A loaded wine cabinet is very heavy and the weight is all in the door swing; unload the racks before moving it, and keep the glass door supported rather than letting it take the cabinet weight.

When to call a technician
Call when the drain is clear, the cabinet is level, the pan is sound and the water still arrives — at that point the leak is inside the insulated shell and needs the cabinet opened. Call immediately if the fluid is oily rather than watery, if water is reaching an outlet or the machine bay wiring, or if the cabinet has tripped protection since the leak began. On Avanti WBC the first three checks take under an hour and resolve most of these. Check the plate before acting on any of this. WBC is a wine and beverage cabinet, and the ranking above is written for that construction rather than for the brand as a whole.
