The short answer
On the Caf PVD family the first question is not what is leaking but where the water appears: under the crisper drawers, at the front door line, or under the cabinet at the back. 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. Each location has its own short list, and the commonest of all — a defrost drain blocked by an ice plug — puts water under the drawers and then onto the floor.
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.
- 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
- Defrost drain blocked by an ice plug or debris — First: every defrost cycle sends meltwater to the same trough, so once the drain closes the water has nowhere to go but forward.
- Water filter head, cartridge o-ring or a supply fitting — Second: it is the only cause on this list that is under pressure, so it gets worse rather than repeating, and it usually starts at a cartridge change.
- Ice maker fill tube overfilling or misaligned — Third, and easy to confirm by looking at the mould edge for a frost ridge.
- Drain pan cracked, displaced or overflowing — Fourth: the pan sits over the compressor and normally evaporates what reaches it, so water there means either too much water or a pan that has moved.
- Door seal or cabinet level letting warm air condense — Last, and the one to suspect when the water is at the gasket line rather than the cabinet floor.
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
Unplug before any panel comes off — a capacitor can hold a charge after the power is off. Water that has reached the floor may also have reached the wiring at the base of the cabinet, so dry everything before restoring power, and keep the unit off if the breaker has tripped even once during the leak.

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.
