The short answer
Water around an AFD cabinet almost always started as condensate the machine made on purpose and then failed to route away, not as a burst pipe. On a apartment-size refrigerator the route is short and the places it can fail are few, which makes this one of the better faults to diagnose at home.
What you observe on these models
- Water pooling under the crisper drawers before it reaches the floor — On a full-height cabinet that is the defrost drain and almost nothing else.
- More water on humid days than on dry ones — Condensation is weather-driven; a plumbing fault is not.
- Water or a sheet of ice under the crisper — The defrost drain has backed up, frozen, and then found another way out.
- The leak follows the defrost cycle rather than the compressor — Water appearing at intervals through the day is the cycle, not a pipe.
- NEAR MISS — water only after the door has been left open a long time — That is the cabinet catching up with the room, not a leak.
Causes, most likely first on the AFD family
- Defrost drain blocked at the bottom of the evaporator — First on this platform: on a full-height automatic-defrost cabinet this is the leak: water pools under the crisper drawers and then runs out onto the floor at the front.
- Water inlet valve, fill tube or the line to the ice maker — Second: a drip at the valve runs down the back panel and appears behind the cabinet, not inside it, which is how you separate it from the first cause.
- Condensation on the outside of the cabinet — Third: a cold shell in humid air collects water on its own skin, and it puts a puddle on the floor without a drop of it coming from inside.
- Door seals and alignment on a tall door — Fourth: warm air entering at a sagging top corner condenses on the first cold surface it meets.
- Cabinet not level in its space — Last: the drain is designed around a level floor and nothing else.
Check in this order, and why that order
- Check inside under the crisper drawers first — Water pooling there is the defrost drain and nothing else, and it is the commonest leak on a full-height cabinet.
- Flush the drain with warm water from inside the freezer compartment — Reach the outlet at the bottom of the evaporator area; clear it warm, never with a wire.
- Dry everything, then run the cabinet for a day and look again — One inspection cannot tell you whether the water is arriving steadily or all at once.
- Note whether the puddle grows on humid days — Weather-driven water is condensation and drainage, not plumbing.
- Take the drawers and lower shelves out and look at the floor of the cabinet — Water pools where the drain is before it reaches your floor.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On this platform there is no check worth doing that cannot wait the thirty seconds it takes to isolate the machine properly.

When to call a technician
Clearing a drain, levelling a cabinet and replacing a gasket are all owner jobs on a apartment-size refrigerator. On these models the line falls at anything behind a panel and anything on the sealed system. Call without working through anything at all for frost or ice returning within days of being cleared, together with a cabinet that will not hold.
