The short answer
A Caf CXE cabinet that leaks is usually routing meltwater badly rather than leaking supply water. The matrix below lists two model tags that differ only in their trailing revision characters, so a part that suits one usually suits its neighbours, and the tag still decides. The distinction matters: a supply leak is under pressure and gets worse, while a drain fault repeats on the defrost cycle and stops when the drain is cleared.
What you can observe on these models
- The leak appears only every several hours — That period matches the defrost cycle almost exactly and points the whole diagnosis at the drain.
- Damp or buckled flooring in front of the cabinet — A slow leak that has been running for weeks. The source is usually the same drain, not a new failure.
- Water inside the door liner or along the gasket — Condensation from a seal that no longer touches, which is a heat-load problem as much as a water one.
- The filter head area is wet after a cartridge change — An o-ring that did not seat, or a cartridge that does not match the head, both weep under supply pressure.
- NEAR MISS — water inside plus a warm cabinet — Meltwater from a freezer that has stopped holding temperature is a cooling fault. Work the temperature first; the water stops when the cold returns.
Causes, most likely first on this family
- Supply-side leak at the inlet valve, line or filter head — First when the puddle grows whether the unit is running or not: only a pressurised line does that, and only it can flood a floor overnight.
- Blocked defrost drain backing up into the cabinet — Second, and the cause to assume the moment the water is inside the cabinet rather than only on the floor.
- Drain pan displaced by a move or cracked by age — Third: pulling the unit out for any other check reveals it, so it costs nothing extra to rule out at that point.
- Ice maker fill overshoot — Fourth, and it usually arrives alongside an ice-production complaint rather than alone.
- Gasket, door alignment or an unlevel cabinet — Last: condensation at the door is a heat-load symptom. It is real, but it damps a frame rather than wetting a floor.
Check in this order, and why
- Map the water before touching anything — Under the drawers, at the front, or at the back under the compressor — the three locations have almost no causes in common.
- Dry the area and time how long it takes to return — A return every several hours is the defrost cycle and points at the drain; a steady growth points at a supply fitting.
- Flush the defrost drain from inside the freezer — Unplug, clear the trough, and run warm water through until it reaches the drain pan. This clears the commonest cause outright.
- Pull the unit out and inspect the pan and fittings — Look at the pan seat, then run a dry tissue around the inlet valve and filter head to find a slow weep.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before clearing a drain or removing a panel — a capacitor can hold a charge after the power is off, and water plus live electrics is the one combination to avoid entirely. On the Caf CXE family the defrost trough sits directly under the evaporator, so flush it with warm water rather than probing with anything metal.

When to call a technician
Flushing the defrost drain, reseating a filter, emptying a bin and levelling the cabinet are owner jobs on the Caf CXE family. Call when the drain blocks again within weeks of a flush — that usually means a failed drain heater or a check valve rather than debris — and call immediately for any supply-side weep you cannot stop at the shutoff. Water behind a cabinet damages a floor long before it announces itself.
