The answer first
Water from an FFFDD refrigerator has four plausible sources and they are distinguished by location rather than by volume. The list below is ordered on that: each cause is paired with where its water shows up, so the position of the puddle picks the cause rather than the other way round.
How the fault presents
- 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.
- Water at the back, near the wall — On a cabinet with a water supply this is the line or its connection; without one it is the pan.
- Beads of water around the door frame or on the outside of the cabinet — Condensation rather than a leak — warm damp air meeting a cold surface.
- A layer of ice under the bottom drawer — Water sitting in the channel and freezing where the air is coldest.
- NEAR MISS — water plus a new rattle from underneath — A pan that has shifted makes noise and spills at the same time, and both stop when it is seated properly.
What it usually turns out to be, in order
- Defrost drain blocked — Every cycle melts the frost off the evaporator and sends it down a small drain to a pan underneath. Ranked first here: it is both the commonest cause of this complaint on compact refrigeration and the cheapest to rule out, which is the same reason it belongs before anything requiring a panel.
- Drain pan cracked, displaced or overflowing — The pan sits over the compressor so its heat can evaporate what collects. Second on this family: it produces the same complaint as the cause above it, so the two have to be separated before either is acted on.
- Containers or packaging blocking the internal channel — The channel that carries melt to the drain runs along the back of the compartment, and a drawer pushed hard back or a box standing in the channel dams it. Third on this family, and the rank where the cause stops being obvious from the doorway.
Work through it in this order
- Let the location choose the cause — On FFFDD cabinets the position of the water is more informative than its quantity, so the first step is to find where it is arriving rather than how much of it there is.
- 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.
- Empty the bottom of the cabinet and look at the channel — It should be clear along its length and slope toward the drain opening.
Safety before diagnosis
Safety
Isolate first: unplug the machine, or switch off the breaker if the socket is behind the cabinet. A capacitor can hold a charge after the power is off. Then think about the weight — a refrigerator is top-loaded and moves badly on a hard floor, so empty the door shelves before you walk it out, and never let it lean on the tubing at the back.

When to call a technician
Stop and call when the next step would be a panel, a meter or a gauge. On a cabinet this size the components sit close together and a probe in the wrong place shorts something that was not broken when you started.
