The short answer
Water at a wine cabinet usually comes down to one thing: water in the base is part of how this cabinet controls humidity. Next on the list: warm air leaking past the door is condensing and running. Where the water appears — under a drawer, behind the cabinet, or down the door — decides this faster than any tool.
What you observe
- Water where there was none before — Under a drawer, behind the cabinet, or down the door — each points elsewhere.
- A shallow film of water in the base of the cabinet — A humidity-controlled cabinet keeps some water by design.
- Droplets run down the inside of the door — Room air is condensing on a cold surface, which is not a leak.
- A general film of moisture rather than a running puddle — Moisture everywhere at once has no single source.
- NEAR MISS — the cabinet is also failing to hold temperature — Read the cooling page first — that is one fault with two symptoms.
Causes, most likely first on this unit
- Water in the base is part of how this cabinet controls humidity — First on a cabinet that manages humidity, because a small standing reservoir is designed behaviour rather than a fault. What matters is whether the water stays where it belongs or reaches the floor.
- Warm air leaking past the door is condensing and running — Ranked here because a seal fault leaks water as readily as it leaks cold, and only one of those is obvious.
- Condensation rather than a leak — Ranked here because it is worth separating condensation from a genuine leak before anything is dismantled.
- The condensate pan is cracked, overfull or out of position — Last, and worth a look while the coil is being cleaned anyway.
Check in this order, and why
- Note whether the water is inside the base or on the floor — Inside the base is design; on the floor is a fault.
- Paper-test the seal and look for water on the inside of the door — Water on the door rather than the floor means condensation.
- Note whether the water is spread thinly or running from one point — Condensation is general; a leak has a source you can find.
- Isolate the cabinet and check the pan sits square and whole — Everything that drains lands here, so it is always worth a look.
What an owner can safely check
- Dry everything and find out where the water reappears first — The first wet point is the source; mopping blind loses the diagnosis.
Tools: towelsAbout 15 min
- Check whether any water is reaching the floor — Water contained in the base needs nothing done to it.
Tools: torchAbout 10 min
- Paper-test the seal all round and clean the gasket channel — Anywhere the paper slides free is where the air is getting in.
Tools: paper, clothAbout 15 min
- Dry the cabinet fully and watch where water reappears first — The first wet point is the source, if there is one.
Tools: clothAbout 20 min
- STOP HERE before disturbing any water fitting or removing a rear panel — Water under pressure and live terminals in the same space is a service job.
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. A loaded wine cabinet is far heavier than it looks and a glass door is unbalanced the moment it is open — empty it before it is moved, and never carry it alone.
When to call a technician
Call once you have cleared the drain, confirmed the cabinet is level and dried the area, and water still returns. Call without waiting if water behind the cabinet refills after mopping: pressurised water does not stop on its own. Call immediately if water is reaching an outlet, a plug or any electrical connection — switch the circuit off first.

What this page does not cover
This page is written for the brand and the cabinet class, not for one family or model line. Where a family- or model-specific page exists for your cabinet, that page is the more specific answer and it is where to start. Deliberately absent: zone counts, rack configurations, part identifiers and charge figures, which differ between the single-zone, multi-zone and built-in families.
