What is happening, in three sentences
A leaking BCD 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 you actually observe
- It only leaks after the cabinet has been filled — A packed compartment blocks the channel that carries melt to the drain.
- A layer of ice under the bottom drawer — Water sitting in the channel and freezing where the air is coldest.
- 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.
- An old stain on the floor with no visible water now — An intermittent leak on the defrost cycle rather than a continuous one.
- 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.
Causes, most likely first on BCD models
- Defrost drain blocked — Every cycle melts the frost off the evaporator and sends it down a small drain to a pan underneath. On BCD this is where to start, because the alternative first checks all need the cabinet moved or a panel off and this one does 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. 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.
- 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
- Dry everything first — You cannot tell a new leak from an old puddle. Dry the floor and the inside, then come back in a day and look at what has returned and where.
- 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.
- 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.
- Empty the bottom of the cabinet and look at the channel — It should be clear along its length and slope toward the drain opening.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and on a refrigerator the compressor circuit stays live for as long as the plug is in. Leave the door switch wired exactly as it is: it cuts power to the evaporator fan so that a blade is not turning while your hand is past the panel, and defeating it is the one shortcut that turns a nuisance repair into an injury.

When this stops being owner work
The line on this family is the panel: everything above it is owner work, and the moment a diagnosis needs the freezer rear panel off or a meter on a winding, it is a service call. Call immediately if the breaker trips again after a reset, if the cord or plug is warm to the touch, or if you see oil anywhere on the tubing.
