What this means on this line
On the BBM line the puddle position is the most useful single observation. Under the crisper drawers is the defrost drain, behind the cabinet is the supply connection, and on the floor at the front is usually the first of those one stage later.
Symptoms on these models
- The floor is wet only after a defrost cycle — For every model in this family, timing the puddle to the defrost names the drain immediately and excludes the supply connection.
- A white mineral trail at the supply connection — The signature of a slow weep over weeks, and it identifies the exact joint without any test.
- Water appears under the cabinet but the interior is dry — The drip tray or the supply line, since a drain fault backs water into the compartment before it reaches the floor. It does not vary across the models listed on this page.
- The crisper drawers themselves hold water — Backed-up meltwater reaching the lowest point of the fresh-food compartment, which is the classic drain signature.
- The leak began after the cabinet was moved — The drip tray is easily dislodged when an appliance is walked out, and it then delivers the same water to the floor.
- Condensation runs down the inside of the door liner — Humid air entering past a tired gasket, which produces water without any drain fault at all.
- 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.
Why it happens, in order
- A blocked defrost drain — First on the BBM 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. This applies to the whole line rather than to one model.
- 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. The same is true of each model covered here.
- Overfilled or badly closed doors — A door held ajar by a bottle or an overfull shelf admits humid air all day, which produces condensate faster than the drain was designed to clear.
- A drain hose that has come off its stub — Behind the cabinet the hose is only pushed on, and being knocked during a move disconnects it, so meltwater goes straight to the floor with a drain that is perfectly clear.
- A cracked drain trough moulded into the liner — Last because it is rare and because it needs the freezer rear panel off to see, and because every cheaper cause above it produces an identical puddle.
What to check first, second, third
- Find where the water actually appears — First on the BBM line because under the drawers, behind the cabinet and on the floor are three different faults, and the location separates them without any tool. The models in the table behave the same way here.
- 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. That is true of every model this family spans.
Before anything comes apart
Safety
Isolate the cabinet and close the water supply tap before touching the fill line. Never use rigid wire or a sharp tool in a drain opening, because the tubing behind it is thin and easily punctured.

When this becomes a service call
The owner boundary on the BBM line is the freezer rear panel. The drain entry, the tray, the hose and the fill joints are all reachable; the trough and the evaporator are not. That holds across every model this page covers.
