The short answer
A water complaint on the BCS family is usually condensate that has been sent somewhere other than the drain, and only rarely supply water, since not every model in the group is plumbed at all. Water around a cooling appliance is nearly always water the machine made itself, so the question is rarely where it came from and almost always where it failed to go.
What you observe on these models
- Water at the back, near the wall — A wet patch behind the unit points at the drain pan or at the supply connection where the model has one, and both need the cabinet pulled out to see.
- Ice under the drawers or across the base — A drain that has frozen rather than blocked gives ice where water would otherwise be, and it will thaw into a puddle as soon as the cabinet is switched off.
- Damp, a musty smell and no visible puddle — Water that has gone under the cabinet rather than in front of it produces a smell long before it produces a puddle, and floors suffer quietly in the meantime.
- NEAR MISS - the water is warm, or it is coming from a wall fitting — That is household plumbing rather than the appliance, and the appliance is only where it happens to be pooling.
Causes, most likely first on this platform
- Warm humid air getting in past the door — Warm room air carries moisture, and the moment it reaches a cold surface it gives that moisture up. A gasket that has gone hard, a door left standing ajar or a cabinet in a humid room produces water continuously, and it produces it faster than any drain was sized for. One catalogued model means the drain is in one place and the answer is the same for every owner, so the variable is the room and the door rather than the machine.
- Levelling, and which way the water runs — Second on this platform. A forward tilt turns a small internal drip into a floor puddle, so it is worth putting a level on the cabinet before assuming a part is at fault.
- The drain that condensate is supposed to use — Third here. The drain stays on the list until it has actually been looked at, because a partial blockage produces an intermittent puddle that looks like almost any other cause.
- Meltwater from a heavy frost build-up — Fourth. Frost releasing in bulk is worth ruling in early on any cabinet that has gone a long time without a defrost, because it explains one large puddle that never returns.
- Supply water rather than meltwater — Last. On a plumbed model the supply is always worth eliminating, since a slow weep at a fitting behind the cabinet can run for months unseen.
Check in this order, and why
- Dry everything, then watch where it comes back — Inside, under, or out of the front door are three different faults, and an old puddle cannot tell you which one you have. Give it a day after drying before deciding anything. With one catalogued entry behind this page, whatever you find here is the answer for every owner of the model.
- Do the paper test around the whole door — Close the door on a sheet of paper at several points and pull. Anywhere it slides free is letting room air in, and room air is where nearly all of this water comes from.
- Put a level on the top of the cabinet — Level or very slightly back is right. Tipped forward sends meltwater out under the door and stops the door pulling itself shut, and it is adjusted at the feet in a couple of minutes.
Before you open anything
Safety
Isolate the machine at the plug or the breaker before working behind it or drying underneath it. Where the model is plumbed, close the water shutoff before touching a fitting rather than after. Never push wire or a screwdriver into a drain opening to clear it - the tubing behind the liner is thin, and warm water does the job without the risk.

When to call a technician
Drying, levelling, clearing a drain with warm water and straightening a supply line are owner work. A cracked drain pan, a failed valve or a heater in the drain path is not. Go straight to a call where a breaker has tripped, where the water is warm and clearly not the appliance, or where the floor under the cabinet has started to lift.
