The short answer
On the BC family, a cabinet that is putting water where it should not be usually comes down to door seal letting warm humid air in. The quickest way to place it is to run a paper strip around the whole door frame.
What you observe
- 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.
- Water only after the cabinet was moved or loaded — Tilting a cabinet moves where the melt water runs, and a drain pan knocked out of its rails empties onto the floor.
- A steady drip rather than a pool — A drip that continues regardless of the cooling cycle points at a supply connection, which is the one leak that does not stop on its own.
- NEAR MISS: water inside with a cabinet that is also warm — If the cooling has gone as well, start with the cooling page: the water is a symptom of the same fault.
Causes, most likely first
- Door seal letting warm humid air in — Warm air carries moisture, and every litre of it that leaks past a tired seal leaves its water behind inside the cabinet as condensation or as frost that later melts.
- Defrost drain blocked or frozen — It ranks second 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.
- Drain pan displaced, cracked or overflowing — A pan that is simply overwhelmed is a symptom rather than a cause: it means the cabinet is defrosting more than it should, which puts the door seal back in the frame.
- Cabinet not level, tilting the water the wrong way — These cabinets are designed to sit very slightly back, so melt water runs to the drain and the doors self-close; a unit tipped forward sends that water to the front instead.
- Body: The prefix this family uses marks a single-compartment cooler rather than a combination cabinet, so there is no separate freezer space, no air being moved between two compartments, and no defrost cycle of the kind a two-door cabinet runs. Where that departs from the brand-generic order is door seal letting warm humid air in, which moves up on these models because there is no fan moving air between two compartments here, so heat rejection at the cabinet wall and the door seal carry more of the load than they would on a two-door unit.
Check in this order, and why
- 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.
- 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.
- 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 single-compartment cabinet the second check is quicker than it would be on a two-door unit, because there is only one space to judge.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before you touch anything at the back, and before any water goes near it. Water and the compressor deck do not mix: the relay and the capacitor there are live, and a capacitor can hold a charge after the power is off.

When to call a technician
Call when the drain has been cleared, the seal checked, the cabinet levelled and the pan reseated, and water still arrives. Call straight away, without working the list, if the water is a steady drip that does not follow the cooling cycle and the cabinet is plumbed, because that is house pressure behind it rather than melt water.
