The short answer
Water inside or under the BAF line is usually the defrost drain rather than a plumbing failure. These cabinets carry meltwater from the evaporator through a small drain to a tray above the compressor, and that route is narrow enough for a plug of ice or debris to back it up into the compartment.
What you observe
- Water pooling under the crisper drawers — On the models listed in the table on this page, the classic blocked defrost drain: meltwater that cannot reach the drain backs up into the lowest part of the fresh-food compartment.
- A sheet of ice on the freezer floor — The freezer-side version of the same fault, where the drain opening has frozen and meltwater refreezes where it stands.
- Water on the kitchen floor in front of the cabinet — Usually a compartment that has overflowed forward past the door seal rather than a leak from the back of the machine. The models in the table behave the same way here.
- NEAR MISS: the compartment is warming as well as wet — Then the frost build is the primary fault and the cooling-failure page for this family applies first.
Causes, most likely first
- A blocked defrost drain — First on the BAF line by a wide margin. The drain is deliberately small to limit air movement, and a plug of ice or food debris at its entry backs the whole daily defrost load into the compartment. That holds across every model this page covers.
- A door gasket that no longer seals — Second because warm humid air admitted continuously condenses inside the cabinet and overloads the drain even when the drain is clear. It also causes the frost that eventually blocks it. That is true of every model this family spans.
- A drip tray out of position or overflowing — The tray is designed to evaporate what the drain delivers. Knocked out of place when the cabinet was moved, it delivers the same water onto the floor instead.
- A leaking water supply line or its connection — The only part of the appliance under pressure at rest, which is why it is the cause when water appears behind a cabinet that has not been running.
- A cracked drain pan or a split drain hose — Last on this platform because it is rare and because it needs the cabinet out and the rear panel off to see. Every cause above it produces identical puddles and costs nothing to exclude.
Check in this order, and why
- Find where the water actually appears — First on the BAF line because under the drawers, behind the cabinet and on the floor are three different faults, and the location separates them without any tool. It is the same on all the models in the table on this page.
- Clear the defrost drain opening — Second: it is at the base of the freezer rear wall or behind the crisper, and warm water plus a soft flexible line clears the usual plug in minutes.
- Check the door seal with a sheet of paper — Third, because a gasket that no longer grips loads the cabinet with humidity continuously and will refill the drain as fast as you clear it. This applies to the whole line rather than to one model.
Before you begin
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Mop the floor before working, because standing water under a heavy cabinet makes a slip far more likely than the leak itself.

When to call a technician
Call when the drain is proven clear, the gasket seals, the tray is seated and water still appears. On the BAF line that points at the drain pan, the drain hose or the defrost system, all of which sit behind panels that are service work. The same is true of each model covered here.
