In short, on BSC models
Water under an AVG BSC refrigerator is usually condensate that has lost its way out, not a burst pipe. The defrost drain blocks, the pan overflows or the water finds a path down the back wall instead of into the tray. Trace the water to its highest point before assuming anything is broken.
What the owner sees
- A clean, clear puddle that returns within hours — Across the BSC line, fast refilling means a supply line, not condensate — condensate arrives slowly.
- Water arriving only after a heavy shop — On BSC models in particular, a drain that is partly blocked copes until it is asked to do real work, which is why the leak is intermittent.
- Water at the front, just inside the door — For the BSC line, front-edge water with a warm cabinet points at the seal rather than the drain.
- Damp along the door edge with a dry floor — On this family, a dry floor and a damp frame is normal; treat it as a leak only if it puddles.
- Water pooling on the floor of the cabinet, under the crisper — For the BSC line, that is the classic blocked defrost drain: melt water backs up and runs forward instead of down.
- NEAR MISS — a steady drip with the machine switched off — A machine that is off is simply defrosting. Empty it, dry it and judge it once it has been running again for a day.
What goes wrong here, most frequent first
- A blocked defrost drain — It leads because every cabinet makes defrost water daily, so the drain is the one part of the water path that is always working.
- A door gasket letting humid air in — This ranks where it does because it produces water and poor cooling together, and because the paper test finds it in a minute. That holds for every BSC model listed here.
- A drain that freezes shut because the defrost system is failing — It ranks below the simple blockage because it is the same symptom with a harder cause, and it needs a technician.
- A perished or disconnected drain tube — Last of the common causes: the tube hardens with age, cracks at the bend, or falls out of the pan when the machine is pushed back. On the BSC models below the ranking is the same.
The order to work in
- Find the highest point the water reaches — On every BSC model in the table, dry everything, put kitchen paper at likely points and come back: the first sheet to wet tells you where to look.
- Isolate the water supply and see if the leak stops — On this family, if the puddle stops returning with the water off, the fault is in the fill line or the valve.
- Put kitchen paper down and find the highest wet point — Within the BSC family, water runs downhill, so the top of the trail is closest to the source.
- Look at the drain pan under the cabinet — With the plinth off and the unit isolated, check the pan is seated and not overflowing.
Safety before access
Safety
Isolate the machine at the plug or the breaker, and close the water supply if one is fitted; a capacitor can stay charged after the power is off. Never clear a drain with wire or a screwdriver — the tubing and the liner puncture easily and a hole in either turns a free fix into a replacement panel. Leave all switches wired as found.

When to call a technician
Call when the drain refuses to clear, when it clears and refreezes within days, or when water has reached anything electrical. A drain that freezes shut repeatedly is a defrost-circuit fault rather than a blockage, and that is a technician job. So is any leak you cannot trace to a point above the water.
