The short answer for FFFDS models
A leaking FFFDS refrigerator sorts by where the water appears, and that single observation does most of the diagnosis. Water inside under the drawers is the defrost drain. Water on the floor at the front is the pan or the seal. Water at the back is the supply line if the cabinet has one.
What this looks like at the cabinet
- The gasket itself is wet along one edge — That edge is where room air is getting in, and it is where the seal test should start.
- A layer of ice under the bottom drawer — Water sitting in the channel and freezing where the air is coldest.
- Water pooling under the drawers inside the cabinet — The signature of a blocked defrost drain: the melt has nowhere to go, so it collects at the lowest point inside.
- A steady drip that does not stop — Steady rather than cyclic points at a supply connection, and that one is worth isolating immediately.
- NEAR MISS — water plus a cabinet that is no longer cold — That combination is a cooling fault with melt as its symptom, and the cooling article is the right place to start.
Causes in likelihood order on this model group
- Defrost drain blocked — Every cycle melts the frost off the evaporator and sends it down a small drain to a pan underneath. On FFFDS this is where to start, because the alternative first checks all need the cabinet moved or a panel off and this one does not.
- Drain pan cracked, displaced or overflowing — The pan sits over the compressor so its heat can evaporate what collects. Second here, and it is the rank most sensitive to how the cabinet is used — a unit opened all day sees this far sooner than one that is not.
- Door seal letting warm damp air in — A gasket that no longer seals admits room air, and that air gives up its moisture on the first cold surface it meets. Third: real, but it usually announces itself with something the first two causes do not produce, so the earlier checks will have already pointed at it.
The diagnostic order
- Cyclic or continuous — Water that appears every day or two is defrost melt. Water that never stops is a supply, and a supply leak is the one to isolate before diagnosing anything else.
- Find the drain opening and check it takes water — It sits at the base of the compartment. A spoonful of warm water poured in should disappear; if it sits, the drain is the fault.
- Pull the cabinet out and look at the pan — It should sit square on its bracket and be damp rather than brimming. Note whether it is cracked or merely displaced.
- Test the seal with a strip of paper at four points — A strip that pulls out without resistance shows where the air is getting in, and that spot is usually where the water is worst.
Isolate the machine first
Safety
Switch the breaker off or unplug the unit before removing any panel; a capacitor can hold a charge after the power is off. Anything you do behind the freezer rear panel happens next to a fan blade that the door switch is there to stop, so leave that switch alone. If the cabinet has to come out to reach the condenser, clear the run first and move it in short steps rather than one long pull.

Where the owner fix stops
Book a technician once the checks above come back clean, and book one straight away if any of three things is true: the compressor is hot and silent, the breaker will not hold, or there is oil at a joint. Those three each mean the fault has moved past the part of the machine an owner can reach.
