The short answer
Water from a Commercial Cool refrigerator comes from one of three places: melted frost that should have drained away, condensation that should never have formed, or a supply connection on plumbed models. Each leaves the water in a different place, so the first job is to find the puddle rather than to guess the part. nine model numbers share the BD 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
- Leak started after the unit was moved or levelled — A tray knocked out of place or a cabinet now tipped forward so the drain no longer runs the right way.
- Leak started after a filter change — On plumbed models that is the connection, not the cabinet, and it is found with a dry cloth and a torch.
- Water inside the door shelves — Condensation from a seal fault, most obvious on the hinge side.
- Wet insulation smell from the back panel — A long-running leak that has soaked into the cabinet. Stop and get it looked at.
- NEAR MISS — water from an ice maker bin that has fused — A temperature problem rather than a plumbing one, and the ice page covers it.
Most likely first
- Water that should have drained — Ranked first because automatic defrost produces water on every cycle and depends entirely on a small drain hole staying clear. Block it and the fault is guaranteed rather than likely.
- Water that should have evaporated — Second: the tray. It is designed to be overflowed slightly in humid weather and to dry between cycles, so a cracked or displaced tray makes a puddle that follows the compressor cycle.
- Water that should never have formed — Third: condensation from a seal, a door left ajar, or a cabinet in a humid room. The water is real and the cause is air, not plumbing.
- Water from the supply — Last, and only on plumbed models — but the most damaging, because a slow weep at a connection runs continuously rather than cyclically.
Check in this order, and why that order
- Ask what changed recently — A move, a new level, a filter change, hot humid weather, or a door left open. Each maps onto a different cause.
- Check the front lip and the floor under the door — Water there with a dry interior usually means the drain has overflowed rather than a seal has failed.
- Feel the gasket all the way round — Hard, flattened or torn sections at the hinge corners are where condensation starts on cabinets of this age.
- Stop at the drain tube and the tray — Anything beyond — heaters, the defrost control, the inlet valve — is diagnosed on a live appliance behind panels, and that is service work.
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. Water on the floor and electrical parts at the back of the cabinet are a bad combination, so unplug the unit before mopping underneath or pulling it out. Do not clear a frozen drain with a metal wire or a heat gun: the drain tube is soft plastic and a punctured tube leaks permanently and invisibly.

Where the owner line is on these models
Call when the drain has been cleared properly and the water comes back, when the tray is cracked, when a plumbed connection weeps, or when the water has been running long enough to reach flooring or insulation. Those are the cases where the cheap fix has already been tried and what remains — the defrost heater, its control, or a supply fitting — is either behind a panel on a live appliance or a plumbing repair that should be done properly rather than hopefully. Whichever of the nine models in the table above you have, quote the full number from the rating plate when you call — the family letters alone will not get the right part.
