What a leak means on the BC line
On the BC line the overwhelming majority of leaks are defrost water that has not reached the tray. The drain at the back of the compartment blocks with debris or freezes, the water backs up, and it appears under the crisper or on the floor at the front. That is an owner fix. The other causes — a cracked tray, a supply connection, a door that sweats — are found by looking at where the water actually is. seven model numbers share the BC designation. They are in the table below, and the trailing letters that separate them are finish and trim codes rather than different mechanisms — the fault below behaves the same across the list.
What you actually observe
- Water pooling around the base of the door — Drain overflow reaching the front lip, or a gasket that is channelling condensation forwards.
- A steady drip at the back with the compressor running — Tray overflow, which is normal in humid conditions and abnormal if the tray is cracked.
- Food containers sitting in water — The drain again, and a reason to act promptly before the liner floor stains.
- Frost at the back wall plus water below it — The two halves of the same defrost fault, and the clearest version of it.
- NEAR MISS — a smell of damp with no visible water — Check the tray and under the cabinet before assuming food is the source.
Causes, most likely first on the BC line
- Blocked or frozen defrost drain — First on this family and the cause of most leaks on any cabinet with automatic defrost. Debris and food particles reach the drain hole, block it, and the melt water backs up into the liner instead of running to the tray.
- Drip tray overflow, displacement or cracking — Second. The tray sits over the compressor so the heat evaporates the water; a tray knocked askew when the unit was moved, or cracked with age, simply puts that water on the floor.
- Condensation from a failing door seal — Third. Warm humid air entering past a hardened gasket condenses on the cold liner and runs down, which looks exactly like a leak and gets worse in summer.
- Supply line, inlet valve or filter head on plumbed models — Last. Not every model in this family is plumbed, but where one is, the connections at the back are the leak that reaches the floor without ever appearing inside.
Check in this order, and why that order
- Separate cyclic from continuous — Cyclic water is defrost water. Continuous water on a plumbed model is a supply connection and it does not stop on its own.
- Look inside before you look behind — An ice sheet on the liner floor or water under the crisper settles the question without moving the cabinet at all.
- Defrost fully if the drain is frozen — Unplug, empty, leave the doors open and let it thaw naturally. A frozen drain cleared with force refreezes within days.
- Then call if water persists — A drain that blocks again within weeks, a cracked tray, or a connection at the back are the point at which a technician earns the visit.
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. Treat a leak that has soaked into insulation or flooring as urgent rather than cosmetic. Where the model is plumbed, close the supply shut-off before touching any connection, and remember a wet tiled floor and a heavy cabinet make moving it a two-person job.

Where the owner line is on these models
Stop and call where the leak is continuous rather than cyclic on a plumbed model, where the cabinet has water at the back around electrical parts, or where clearing the drain has not held. Everything before that — finding the puddle, emptying the compartment, flushing the drain with warm water, levelling the unit, checking the tray and the gasket — is honest owner work and is exactly what a technician would do first. A technician will ask which of the seven BC models you have before they set off, and the rating plate inside the cabinet is where that number lives.
