The short answer
A leak on the BD line is answered by where the water sits before it is answered by what failed. The model matrix on this page lists one model number under this family badge. Water under the crispers is melt water that could not drain; water at the back with the supply live is a joint; moisture on the liner is the door.
What you observe
- Water pooling under the crisper drawers — The classic blocked defrost drain: melt water backs up inside the liner instead of reaching the drain pan.
- A sheet of ice on the freezer floor — A hard sheet of ice under the bottom freezer basket, built in layers one defrost cycle at a time.
- A steady drip at the back, near the floor — Water at the rear is a supply-side or pan question, and the two are told apart by whether the drip continues with the water off.
- Water running down the inside of the door liner — Moisture on the liner and shelves means the cabinet is running above its setpoint or the door is not sealing.
- Damp or buckled flooring under the appliance — A slow leak that has been running for a while, which is worth treating as urgent even when the volume looks small.
- NEAR MISS — water only in the drain pan at the back — Water sitting in the drain pan at the back is the defrost system finishing correctly and needs nothing.
Causes, most likely first on the BD line
- Supply line, inlet valve or dispenser tubing leaking — First here: the matrix on this page covers a single build rather than a span of generations and the priority is not probability but consequence — supply water keeps arriving while melt water does not.
- Blocked or frozen defrost drain — Second. If the water only appears after the unit has been running, this is almost certainly it.
- Door seal or a door not closing fully — Third: humid room air condensing inside the cabinet, which looks like a leak but is the appliance doing what physics requires.
- Drain pan cracked or off its seat — Last, and usually discovered while the unit is out for one of the checks above.
The check order on these models
- Shut the household water valve and watch for an hour — First because it separates pressurised water from melt water decisively: a leak that stops is supply, one that continues is not.
- With the water off, look for any remaining wetness at the rear — What is left is the pan or the drain tube rather than a live joint.
- Clear the defrost drain at the freezer floor — With supply excluded, this is where interior water comes from.
- Paper-test the gasket all round both doors — Paper-test both door gaskets last, because a door fault shows on the liner rather than on the floor.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker and mop up first; a capacitor can hold a charge after the power is off. Clear a frozen drain with warm water and patience rather than a stiff wire — the tubing behind the liner is thin, and turning a blockage into a hole is not a repair anyone can undo.

Where owner work stops
The condition is whether the leak stops when the household water is shut off. If it does, a joint is involved and it is worth having done properly. If it does not, it is melt water, and clearing the drain and checking the gasket are reasonable owner work on these models. Damp flooring moves the whole thing to urgent regardless of the source.
