The short answer
On the CCUN models, water inside the cabinet and water on the floor are two different faults with two different first checks. Inside means the drain has blocked or the seal is letting warm air in; outside means the tray, the line or a connection at the back.
What you observe
- A pool on the floor under the front of the cabinet — Water that has run forward along the cabinet floor and out under the door.
- Damp or wet food at the back of a shelf — Condensate running down the rear wall before it reaches the drain.
- A sheet of ice on the cabinet floor — Water that pooled and then froze where it stood. It means the drain has been blocked for a while, not that the unit has suddenly started leaking.
- Water at the back, near the base — The tray, its position, or a connection behind the cabinet.
Causes, most likely first
- A blocked condensate drain — First on this family by a wide margin. The drain hole in the cabinet floor is small, it sits where crumbs and label paper collect, and once it closes the water has nowhere to go but forward and out.
- A door seal that is letting warm air in — Second. Warm humid air reaching a cold cabinet condenses on everything it touches, and on a compact unit with a light door a seal that has taken a set produces a steady supply of water rather than an occasional bead.
- Uncovered food and frequent door opening — Every open door delivers humid room air, and uncovered liquid supplies more. On a small cabinet this is enough to overload a drain that is otherwise working.
- Frost melting off the evaporator in a lump — When a frost sheet finally lets go it arrives as more water at once than the drain can take, so a cabinet with a frost problem leaks intermittently rather than steadily.
Check in this order
- Close the door on a strip of paper at several points around the opening — A seal that does not grip explains a steady supply of condensate without anything being blocked at all.
- Pull the cabinet out and look at the tray under it — Check it is in position and not overfull before assuming anything inside the cabinet is at fault.
- Look at the rear wall inside for frost — Only after the drain is clear.
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. If the unit stands on a circuit shared with other outlets, isolate at the breaker rather than at the plug, because water on the floor around a plug is exactly the situation the breaker is there for.

When to call
Call when the drain is clear, the cabinet is level, the seal grips and water still appears. That combination points at a cracked channel, a failed fitting or a frost problem with a cause of its own, and all three are behind a panel.
