The short answer
A Bull cabinet that leaks is usually routing meltwater badly rather than leaking supply water. The matrix below lists two model tags that differ only in their trailing revision characters, so a part that suits one usually suits its neighbours, and the tag still decides. The distinction matters: a supply leak is under pressure and gets worse, while a drain fault repeats on the defrost cycle and stops when the drain is cleared.
What you can observe on these models
- Water pooling under the crisper drawers — The classic blocked defrost drain: meltwater backs up in the trough and spills forward into the cabinet floor instead of leaving through the drain.
- A thin sheet of ice under the drawers or at the freezer floor — The same blockage caught earlier. The trough refreezes between cycles and the sheet grows with each defrost.
- A puddle across the floor at the front of the unit — Cabinet water that has overflowed forward, or a door that is not sealing and is condensing on the frame.
- NEAR MISS — water inside plus a warm cabinet — Meltwater from a freezer that has stopped holding temperature is a cooling fault. Work the temperature first; the water stops when the cold returns.
Causes, most likely first on this family
- Defrost drain blocked by an ice plug or debris — Ranked first on these models because it is both the commonest cause and the one that produces the exact under-the-drawers pattern owners describe.
- Water filter head, cartridge o-ring or a supply fitting — Second because a weeping fitting behind a cabinet is invisible until the floor tells you, which makes it worth ruling out early.
- Ice maker fill tube overfilling or misaligned — Third: overfill freezes under the bin and then melts as a sheet, so the water appears in the freezer rather than the fresh-food side.
- Drain pan cracked, displaced or overflowing — Fourth — visible in one look once the unit is pulled out, which is why it comes after the checks that do not need that.
- Door seal or cabinet level letting warm air condense — Last: condensation is a genuine cause but it produces damp rather than puddles, and it is usually secondary to one of the causes above.
Check in this order, and why
- Close the water shutoff behind the cabinet — If the puddle stops growing, the fault is on the supply side and everything inside the cabinet can wait.
- Check the filter head and the cartridge collar — Most supply weeps start at a cartridge that was replaced, cross-threaded or does not match this head.
- Open the freezer floor and look for an ice sheet — A sheet under the drawers or the bin is the drain or the fill tube, and it is the evidence that survives after the floor has been mopped.
- Level the cabinet last — A forward tilt turns a small pan overflow into a floor puddle, so correct it once the real source is closed.

Safety
Unplug the refrigerator or switch off its breaker before clearing a drain or removing a panel — a capacitor can hold a charge after the power is off, and water plus live electrics is the one combination to avoid entirely. On the Bull refrigerator line the defrost trough sits directly under the evaporator, so flush it with warm water rather than probing with anything metal.

When to call a technician
Flushing the defrost drain, reseating a filter, emptying a bin and levelling the cabinet are owner jobs on the Bull refrigerator line. Call when the drain blocks again within weeks of a flush — that usually means a failed drain heater or a check valve rather than debris — and call immediately for any supply-side weep you cannot stop at the shutoff. Water behind a cabinet damages a floor long before it announces itself.
