The short answer
Water on the floor around the Caf QF family comes from one of three places: the defrost drain, the fill or filter connections, or the drain pan. The matrix below lists two model tags that differ only in their trailing revision characters, so a part that suits one usually suits its neighbours, and the tag still decides. Two of those are owner-clearable, and the third is a part. Locating the water before opening anything is what keeps this from becoming a long job.
What you can observe on these models
- 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.
- 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.
- 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 — Ranked first because the frost ridge at the mould edge is visible evidence before anything is dismantled.
- Defrost drain plugged at the trough or the check valve — Second: it is the default cause for fresh-food-side water and it survives every other repair until the drain itself is cleared.
- Filter cartridge seating or an aftermarket cartridge — Third because it is the cause that starts on a date the owner can name — the day the filter was changed.
- Drain pan and levelling — Fourth: a cabinet tilted forward carries pan water to the front edge and drips it where nobody expects a leak.
- Door seal condensation — Last on this platform, and worth checking only when everything upstream is dry.
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.

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 QF 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
Flushing the defrost drain, reseating a filter, emptying a bin and levelling the cabinet are owner jobs on the Caf QF family. Call when the drain blocks again within weeks of a flush — that usually means a failed drain heater or a check valve rather than debris — and call immediately for any supply-side weep you cannot stop at the shutoff. Water behind a cabinet damages a floor long before it announces itself.
