The short answer
A Caf CHE cabinet that leaks is usually routing meltwater badly rather than leaking supply water. The matrix below carries a single model tag, so there is no revision fork to work around on this family: what holds for that tag holds for the line. 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
- 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.
- Water pooling under the crisper drawers — The classic blocked defrost drain: meltwater backs up in the trough and spills forward into the cabinet floor instead of leaving through the drain.
- A thin sheet of ice under the drawers or at the freezer floor — The same blockage caught earlier. The trough refreezes between cycles and the sheet grows with each defrost.
- 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
- 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
- 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
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
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.
