The short answer
On the KS models, water inside the cabinet and water on the floor are two different faults with two different first checks. Inside means the drain has blocked or the seal is letting warm air in; outside means the tray, the line or a connection at the back.
What you observe
- A stale smell alongside the water — Standing water in the base has been there long enough to go stale, which tells you the drain has been blocked for some time.
- A pool on the floor under the front of the cabinet — Water that has run forward along the cabinet floor and out under the door.
- Water at the back, near the base — The tray, its position, or a connection behind the cabinet.
- Standing water inside, under the bottom shelf or drawer — Condensate that has not reached the drain at all. This is the commonest form on a compact cabinet.
Causes, most likely first
- A blocked condensate drain — First on this family by a wide margin. The drain hole in the cabinet floor is small, it sits where crumbs and label paper collect, and once it closes the water has nowhere to go but forward and out.
- A door seal that is letting warm air in — Second. Warm humid air reaching a cold cabinet condenses on everything it touches, and on a compact unit with a light door a seal that has taken a set produces a steady supply of water rather than an occasional bead.
- The ice or water supply line and its fittings — On models plumbed for water, a connection at the back or a line pinched when the unit was pushed home will leak under pressure and only at the back. It is lower on this list because most of this family is not plumbed.
- A cracked drain channel or tray — Last. Plastic that has been frozen, thawed and knocked for years eventually splits, and the water then appears somewhere with no obvious path to it.
Check in this order
- Find where the water starts, not where it ends — Dry everything, put paper down at the front and the back, and see which wets first.
- Look at the rear wall inside for frost — Only after the drain is clear.
- Close the door on a strip of paper at several points around the opening — A seal that does not grip explains a steady supply of condensate without anything being blocked at all.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water and a live cabinet do not belong in the same job - isolate the unit before you kneel down to it, and dry the floor before you stand anything electrical on it.

When to call
Call if water appears at the back under pressure rather than collecting slowly, because that is supply water and not condensate, and it will not stop on its own. Call also if a frost sheet keeps returning after the drain is clear - the leak is then a symptom and the cabinet needs diagnosing instead.
