The short answer
A Caf CQE 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
- 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.
- 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.
- 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
- Defrost drain blocked by an ice plug or debris — Ranked first on these models because it is both the commonest cause and the one that produces the exact under-the-drawers pattern owners describe.
- Water filter head, cartridge o-ring or a supply fitting — Second because a weeping fitting behind a cabinet is invisible until the floor tells you, which makes it worth ruling out early.
- Ice maker fill tube overfilling or misaligned — Third: overfill freezes under the bin and then melts as a sheet, so the water appears in the freezer rather than the fresh-food side.
- Drain pan cracked, displaced or overflowing — Fourth — visible in one look once the unit is pulled out, which is why it comes after the checks that do not need that.
- Door seal or cabinet level letting warm air condense — Last: condensation is a genuine cause but it produces damp rather than puddles, and it is usually secondary to one of the causes above.
Check in this order, and why
- Empty the ice bin and look under it — A frozen sheet under the bin means fill overshoot, which is a different repair from a blocked drain even though both end as water.
- Clear and flush the defrost drain — Do this even if another cause is found — a partly blocked drain is what turns any small amount of water into a visible leak.
- Run a tissue along the door gasket — Damp along the seal line with a dry cabinet floor moves the whole diagnosis to condensation and door alignment.
- Inspect the drain pan with the unit pulled out — Cracks show as a dry pan with a wet floor beneath it, which is the one pattern that cannot come from anywhere else.
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.
