Start here
On the BUFR line a leak is nearly always the defrost drain rather than a sealed-system fault, and this platform puts the drain outlet where a slug of ice can hold the whole melt back for days before anything reaches the floor. The brand-generic advice is right about the cause; what changes here is the access, because on the models listed in the table on this page the trough is reached from inside the freezer rather than from behind the cabinet.
The symptoms, and their near misses
- Damp or lifting flooring in front of the machine — Swelling at the board edges under the door line means this has been going on for weeks, not days.
- The leak follows a big shop or a hot day — A cabinet filled with warm food runs longer, produces more melt, and overwhelms a drain that copes the rest of the time. Owners of the models listed in the table on this page describe this in almost identical words.
- Water is standing under the crisper drawers — The base of the fresh-food compartment holds a film of water the drawers hide. It is the first place melt collects when the drain outlet is iced.
- The kick plate at the base is wet on the inside — Remove the plate and look behind it: water there means the melt is escaping between the trough and the pan rather than at the door.
- A sheet of ice has formed on the freezer floor — A flat, clear slab under the lowest basket rather than the usual furry frost. Frost is normal; a slab is drainage.
- NEAR MISS — ice has stopped and the cabinet is dry — No water at all with no ice is an ice-maker or supply fault, and belongs on the ice page for this appliance.
- NEAR MISS — the water is soapy or coloured — That is coming from something else in the room. A clean appliance leak is clear and odourless.
The ranking that matters
- A failed defrost heater or its control — Top of the list here. Genuinely last, and it produces a different picture: a thick frost sheet that never clears rather than periodic clean water. When the heater does fire after a long failure, the whole backlog arrives at once. The BUFR line is no worse than its siblings here, but it is no better either.
- A blocked or mis-routed drain hose behind the cabinet — Then this. A hose that has been displaced during a clean sends the melt down the back of the cabinet rather than into the pan, and the floor gets all of it.
- A water filter head weeping after a cartridge change — Next after those two. A change of filter followed by a new leak is not a coincidence: reseat the cartridge with the seal wetted. On the models listed in the table on this page this is the check that decides the job.
- A frozen or blocked defrost drain — Fourth, and getting rarer. The commonest cause by a wide margin. The drain outlet sits in the coldest part of the airflow, so the last of each melt refreezes at the lip until a plug forms; the next cycle then overflows the trough into the cabinet.
- A leaking water supply line or its fitting — Rarer again. Compression unions loosen with cabinet vibration, and a plastic line that has been pinched behind the machine splits at the crease rather than at the fitting.
The diagnostic order
- Find where the water actually starts — Dry everything, lay kitchen paper along the door line and behind the cabinet, and read it in the morning. Front means drain, back means supply.
- Inspect the supply union and the shut-off valve — With the cabinet pulled forward, dry both fittings and watch them for a few minutes. A weeping union shows a bead within that time. On the BUFR line this is the part that is reachable first.
- Look at the drip pan over the compressor — A dry pan on a leaking cabinet proves the melt is not reaching it and sends you straight to the drain.
- Take the base kick plate off and look behind it — The space behind the grille is where a mis-routed hose hides its evidence.
Before you open anything
Safety
Two hazards matter on this appliance: stored electrical charge and the sealed system. Unplug the appliance or switch off its breaker before removing any panel, and leave anything carrying refrigerant to a licensed technician with recovery equipment.

When to call a technician
Book a visit once the trough has been flushed twice and the floor still wets, or when the water is arriving from behind with the pan intact. Both of those are past the point where warm water and a cloth will help.
