The short answer
Every cabinet in the FFFDD family produces water continuously while it runs and has one route for getting rid of it, so this page is about what happens when that route stops working. 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.
- Beads of water on the outside of the cabinet — That is condensation on cold metal rather than a leak, and it travels with high room humidity, a door left ajar, or a seal no longer doing its job.
- A puddle on the floor at the front — Water at the front has usually run forward along the base, which means either the cabinet is tilted the wrong way or it has overflowed something at the back.
- NEAR MISS - water arrived with the ice stopping — A failed supply line does both at once on a plumbed model, and the ice production page takes that combination from the useful end.
Causes, most likely first on this platform
- A door that is not closing properly — Room air carries moisture and gives it up the instant it meets a cold surface. A gasket gone hard, a door left standing open or simply a humid room produces water continuously, and faster than any drain was ever 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.
- A blocked or frozen defrost drain — Second on this platform. The drain stays on the list until it has actually been tested, because a partial blockage gives an intermittent puddle that mimics nearly every other cause here.
- Ice that has finally let go — Third here. 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.
- The cabinet is tilted the wrong way — Fourth. A forward tilt turns a small internal drip into a floor puddle, so it is worth a level on the cabinet before any part is blamed.
- The supply line, on models that are plumbed — Last. On a plumbed model the supply is always worth eliminating, because a slow weep at a fitting behind the cabinet can run for months before anyone sees it.
Check in this order, and why
- Find the drain and check that it runs — There is usually a small opening at the base of the cold surface. A little warm water poured in should disappear; if it backs up, you have found the fault. With one catalogued entry behind this page, whatever you find here is the answer for every owner of the model.
- 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.
- 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.
Before you open anything
Safety
Switch off at the plug or the breaker before any panel comes off or any water is mopped from behind the cabinet, and give the capacitor a moment. Get help before walking a heavy cabinet out onto a wet floor. If water has reached a socket or a connector, leave the circuit off and call rather than drying it and trying again.

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.
