The short answer
Leaks on the Caf CAE 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. One model tag covers this family in the matrix below, which keeps parts ordering simple and leaves the whole of the diagnosis to the symptom. That split decides everything below.
What you can observe on these models
- 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.
- 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.
- 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
- Ice maker or dispenser water path overfilling — First on a cabinet where the water is in the freezer and the bin: fill overshoot is the only cause that puts water exactly there.
- Defrost drain plugged at the trough or the check valve — Second, and it comes back within weeks if the plug is melted without flushing the line.
- Filter cartridge seating or an aftermarket cartridge — Third: a cartridge that does not match the head weeps at the collar under pressure, often only after the next fill.
- Drain pan and levelling — Fourth, and settled with a level rather than a part.
- Door seal condensation — Last: the least water of any cause here, and usually a consequence of a door left ajar rather than a failure.
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
Close the water shutoff and power the unit down before touching the inlet valve, the filter head or any fitting; a capacitor can hold a charge after the power is off. The line stays pressurised until it is bled, so open fittings into a towel. Dry the floor before moving the cabinet — a wet floor under a loaded refrigerator is how people get hurt moving one.

When to call a technician
The line here is pressure: unpressurised meltwater is yours to clear, pressurised supply water is not. Call for anything at the inlet valve or the line fittings, for a drain that refuses to stay clear, and for a cracked pan that needs the unit pulled and the compressor area accessed. Call the same day if flooring is already buckling — the repair and the damage run on different clocks.
