In one paragraph
BC models take this one slightly differently. Water on the floor in front of a refrigerator almost always arrives by one of two routes: the defrost drain has blocked and is overflowing inside, or the supply line to the ice and water dispenser is weeping behind the cabinet. Where the puddle sits tells you which. The departure from the generic page is in where the first check goes.
Signs and near misses on a BC unit
- A damp patch on the wall or floor behind the appliance — That is the supply side, not the defrost side, and it is a fitting or a line. It is the first thing worth confirming on a BC unit.
- Water only after the appliance has been moved — A line that has been kinked, pulled or unseated during a clean is the most likely story.
- The puddle is on one side rather than centred — Useful: melt water leaving a cabinet that is out of level goes to the low corner.
- Damp under the appliance with a dry floor in front of it — Something at the back or underneath, which puts the drip tray and the supply line in scope.
- NEAR MISS: the cabinet is also warm — Then the leak is a symptom of a cooling fault, and the cooling page is the right one to read first.
Ranked causes on the BC line
- A defrost drain blocked with ice or debris — Ranked first by a wide margin. Every automatic-defrost refrigerator makes melt water on a cycle, and the only path out is a narrow drain that clogs with food fragments and then freezes solid. This holds its place across the BC models listed below.
- A misaligned or frozen ice-maker fill tube — Water that misses the mould runs down the compartment, and the leak follows the ice-maker cycle rather than the defrost cycle.
- A cracked water reservoir or dispenser line inside the door — Last, because it is the least common. It shows as water in the door shelves rather than at the back.
Check in this order, and why
- Pull the crisper drawers out and look at the liner floor — Standing water there is the blocked-drain signature and it is visible in seconds. The BC layout is the reason it comes first here.
- Put a spirit level on the top of the cabinet — A unit tilted forward drains the wrong way, and it takes a turn of the front feet to correct.
- Note how often the water appears — Every few days is the defrost cycle; continuously is the supply side. One observation, two very different lists.
Safety first
Safety
Power off at the breaker before opening anything, and shut the water off before disturbing a line. A refrigerator is heavy: empty it before you move it, and walk it rather than drag it, because a dragged unit kinks the very line you are trying to inspect.

When this becomes a service call
Call when the leak follows no pattern you can pin to the drain or the supply, or when it returns within days of a flush. A drain that refreezes that quickly is a defrost fault, and diagnosing which component takes a technician.
