Find the water before the part
A leak is diagnosed by location and timing. Water inside the cabinet under the crisper means the defrost drain. Water on the floor at the front means the same fault one stage later. Water at the back means the tray or a connection. Water that appears only in humid weather usually means the seal. The BCD designation spans five model numbers in the table below. Which one you have decides the part number, not the repair — the fault below is the same across the line.
What you actually observe
- Water appears every few hours rather than continuously — Cyclic water is defrost water, which points at the drain and away from any supply connection.
- Wet cardboard or packaging on the lowest shelf — Often the first sign, seen before any free water is visible.
- A trickle down the inside of the back wall — Melt water taking the wrong route because the drain below it is not accepting it.
- Floor wet at one front corner only — Tells you which way the cabinet leans, and levelling is part of the fix.
- NEAR MISS — water only after a power cut — Thawed frost rather than a fault. Dry it, and watch whether it comes back.
Ranked causes on these models
- The drain hole at the back of the compartment — Ranked first because it is both the commonest cause and the one an owner can clear. Find it at the base of the rear wall, below the evaporator area.
- Ice over the drain rather than debris in it — Second. A drain that freezes rather than blocks gives the same symptom and needs the cabinet off and empty rather than a poke with a turkey baster.
- Gasket and door alignment — Third. Humid air entering continuously produces condensation faster than the drain can carry it away, so a seal fault presents as a drain fault.
- Tray, connections and the compressor compartment — Last, and the place to look when there is water on the floor and none inside the cabinet at all.
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
The owner line on these models is the drain and the tray. Clearing a blocked drain, thawing a frozen one, levelling the cabinet, reseating a tray and paper-testing the gasket are all yours, and they resolve the large majority of leaks. Call when the drain blocks again within weeks, when the tray is cracked, when a supply connection weeps on a plumbed model, or when water has reached insulation or flooring. Anything involving the defrost heater, the defrost control or the inlet valve is diagnosed on a live appliance behind a panel. A technician will ask which of the five BCD models you have before they set off, and the rating plate inside the cabinet is where that number lives.
