The short answer for this family
On the Allavino CDWR family, water inside the cabinet or on the floor beside it is usually a blocked defrost drain. The build group your model falls in decides whether one circuit or a divided compartment is holding the temperature. The brand-generic order holds at the head here; what this platform changes is the order below it. The checks at the head of the ranking cost nothing but time; the cause at its foot is not owner work at any stage.
What you observe on these models
- Which of the family's models you are standing in front of — The matrix on this page is seven cabinets whose suffix splits the family into a first build group and a second build group, and that is worth reading first, because the build group your model falls in decides whether one circuit or a divided compartment is holding the temperature.
- Water pooling under the bottom drawer or on the cabinet floor — Melt water that could not reach its drain has to go somewhere, and this is where it collects.
- A sheet of ice under the drawers — The same blocked path, found later. The pool froze before anyone noticed it.
- Water on the floor at the back — A supply fitting or a line, not anything happening inside the cabinet.
Causes, most likely first on the CDWR family
- A blocked defrost drain — Ranked first because the build group your model falls in decides whether one circuit or a divided compartment is holding the temperature.
- A door that is not sealing — Second.
- The drain pan and the evaporation path — Third. It explains water that appears in a rhythm rather than continuously, which is the pattern to ask about.
- The water supply line and its fitting — Fourth. Less common than the internal causes above, but it is the one that puts water behind the cabinet rather than under it.
- A cabinet that is not sitting level — Last. It makes other causes worse more often than it causes this alone.
- Body: This is not the brand-generic ranking. The head of the ranking matches the brand-generic order, but below it the water supply line and its fitting moves up to fourth place, because the platform here is a compact cabinet with one sealed system feeding a divided compartment, the divider carrying its own damper and sensor.
Check in this order on these models
- Find the drain hole at the base of the evaporator area and clear it — Warm water down the hole until it runs freely. This is the single most common cause of water inside a refrigerator cabinet.
- Walk the seal with a sheet of paper — A seal that lets warm air in makes condensation continuously, and the condensation is the water you are looking at.
- Look at the pan under the cabinet — It should be damp, not overflowing, and it should be sitting square on its rails. A cracked or displaced pan puts every defrost cycle on the floor.
- Dry the supply fitting and run a cycle — Then look again. A fitting that re-wets itself is weeping, and it will keep weeping until it is remade.
- Body: The order follows the ranking, and the access decides the rest: on these models the machine compartment is reached from the back, and the sensor and damper hardware from inside the cabinet.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel, and before putting your hands anywhere near standing water inside it; a capacitor can hold a charge after the power is off. Turn the water supply off at its valve before touching any fitting.

Where the owner limit falls on these models
Call when the drain is clear, the seal holds and the water still returns, when water is arriving from the machine compartment, or when a supply fitting weeps after being remade. A leak that has soaked into cabinetry or flooring should be looked at quickly for the damage rather than for the appliance.
