The short answer
Leaks on the Caf CIP family follow the defrost cycle, so timing is evidence: water that appears every several hours in a small amount is drain-side, while a puddle that grows steadily whether the unit runs or not is supply-side. Two model tags make up this family in the matrix below: close enough that the checks are common to all of them, far enough apart that parts are ordered by tag. That split decides everything below.
What you can observe on these models
- A puddle across the floor at the front of the unit — Cabinet water that has overflowed forward, or a door that is not sealing and is condensing on the frame.
- Water at the back, under the compressor area — A cracked or displaced drain pan, or a supply fitting weeping at the inlet valve.
- A steady drip from the dispenser after each use — Normal for a second or two; a drip that keeps going is the dispenser valve or a line that is holding pressure.
- The leak appears only every several hours — That period matches the defrost cycle almost exactly and points the whole diagnosis at the drain.
- NEAR MISS — water only in the ice bin — A wet bin with normal temperatures is an ice-maker fill or harvest problem and belongs on that page.
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
- Close the water shutoff behind the cabinet — If the puddle stops growing, the fault is on the supply side and everything inside the cabinet can wait.
- Check the filter head and the cartridge collar — Most supply weeps start at a cartridge that was replaced, cross-threaded or does not match this head.
- Open the freezer floor and look for an ice sheet — A sheet under the drawers or the bin is the drain or the fill tube, and it is the evidence that survives after the floor has been mopped.
- Level the cabinet last — A forward tilt turns a small pan overflow into a floor puddle, so correct it once the real source is closed.
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 CIP 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
Call once the leak needs the inlet valve, the filter head or the drain tube replaced, or when the water is arriving from inside the sealed insulation rather than from a visible path. On these models that means panels and a harness, not a mop. Call urgently if the breaker has tripped during the leak or if the wiring at the cabinet base has been wet.
