The answer first
On the BCD family, a cabinet that is putting water where it should not be usually comes down to defrost drain blocked or frozen. Start with one thing: find the drain hole at the base of the evaporator area and look at it. Every cause below is owner-checkable before anything is dismantled.
What the owner actually sees
- Water at the back of the cabinet only — A leak confined to the rear points at the drain pan, the tubing or a supply connection rather than at anything inside.
- Damp or beads of water on the inner walls — Condensation inside is warm air getting in, which is a door and seal question before it is a plumbing one.
- A wet patch that appears once a day and dries — Anything on a daily rhythm is tied to the defrost cycle, which runs on a timer rather than on demand.
- NEAR MISS: ice fused in the bin and no floor water — That is the ice maker page, where fused cubes and slow production are covered properly.
The ranking, and why it is this one
- Defrost drain blocked or frozen — It ranks first because the symptom matches so precisely: water under the drawers or on the freezer floor on a daily rhythm is melt water that had nowhere to go.
- Door seal letting warm humid air in — On a compact cabinet the door is most of the front and the seal is a single magnetic strip, so a strip that has taken a set costs proportionally more here than on a large unit.
- Drain pan displaced, cracked or overflowing — The pan under the compressor is where all the melt water goes to evaporate, and it only works while it is seated in its rails and intact.
- Cabinet not level, tilting the water the wrong way — It ranks here because it is the cause that best explains a leak that started the week the kitchen was rearranged and nothing else changed.
- Body: The prefix this family uses marks a combination cabinet: cold is made in the freezer side and moved across to the fresh-food side, which is why an airflow fault here shows as one compartment working and the other not. That order is the brand-generic order for this symptom, because nothing in how this line is built moves any of these causes past another.
What to check first, second, third
- Find the drain hole at the base of the evaporator area and look at it — A plug of ice or a dark deposit in the hole is the answer, and the water on the floor is simply what could not get past it.
- Run a paper strip around the whole door frame — Close the door on it and pull: anywhere it slides out freely, warm air is going in at that point all day.
- Look under the back of the cabinet at the pan — Water on the deck beside the pan, or a pan sitting off its rails, is visible in a few seconds with a torch.
- Body: The order follows the ranking above rather than the layout of the cabinet: each check either confirms the cause above it or removes it, and they are arranged so that the free checks come before anything that needs the unit moved or a panel off. On a two-compartment cabinet, comparing the two spaces against each other is worth doing first, because it splits an airflow fault from a cooling fault before anything is opened.
Safety first
Safety
Cut the power at the plug or the breaker first, then deal with the water. Mop the floor before you start moving anything, because a loaded cabinet on a wet floor slides unpredictably and these units are top-heavy with the doors free to swing. Where the cabinet is plumbed, close the supply tap before touching any fitting and expect the water already in the line to come out. Use warm water rather than boiling to clear a drain, and never use a metal tool inside the cabinet liner.

The owner side of this page is the drain, the seal, the level, the pan and the tube behind the cabinet. All of it is reachable and none of it needs a meter.
