The short answer
Most leaks on this roster are a defrost drain that has iced shut or a cabinet that has simply been left above temperature. A seal that is not closing admits humid air, which becomes frost, which becomes water the moment anything warms. Work out where the water is before deciding what it is. One listing carries this family key, so nothing here has to be hedged across generations.
Where the water shows up
- Water pooling on the floor in front of the cabinet — Meltwater that has escaped rather than gone down the drain. Something warmed, or something is blocked.
- Water appeared after a power cut — Thawed frost. Not a fault, though it is worth checking what the contents did while the power was off.
- A wet patch that returns after every defrost — The drain path is restricted rather than blocked, so it cannot keep up with the volume.
- Heavy frost on the seal or the lid edge — Humid air getting in. Frost at the seal today is water on the floor next week.
- Water under the cabinet but none inside — The drain is working and the pan beneath it is overfull, displaced, or cracked.
- NEAR MISS — food has softened as well — Then the cooling fault is the important one and this page is describing its symptom.
The ranking for this platform
- Defrost drain frozen or blocked — First on this roster. The drain sits at the coldest point of the cabinet, so a slow drain freezes shut, and food debris that reaches the channel finishes the job over a season.
- Seal not closing, letting humid air in — Second, and the upstream cause of most of the rest. Air that gets in becomes frost, frost becomes water, and the drain was never sized for that much of it.
- Defrost pan displaced, cracked or overfull — Where a cabinet has a pan beneath it, a pan knocked out of position when it was last moved will spill everything the drain delivers to it.
- Frost build-up beyond what the drain can handle — On a manual-defrost cabinet, a very thick layer melts faster than the channel can carry it, so the water goes over the edge instead. The fix is a shorter defrost interval.
- Cabinet not holding temperature at all — Last as a cause and first as a concern. A cabinet that has stopped cooling produces a great deal of water, and the water is the least of the problems it is reporting.
The diagnostic order for this family
- Put a thermometer in and leave it a few hours — If the cabinet is not holding, the water is a symptom and the cooling page for this family is where to go next.
- Close the lid or door on a strip of paper at several points — Paper that pulls out freely marks where humid air is getting in and where the frost will be heaviest.
- Check the cabinet is standing level — The drain channel is a gravity feature and a forward lean defeats it completely.
- Flush the drain channel with warm water — Clears an ice plug without tools. Never use a metal probe — the tubing behind the channel is soft.
- Look underneath for a pan and check it is seated — A pan knocked out of position when the cabinet was last moved spills everything it is given.
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. A chest cabinet is extremely heavy and the lid is heavier than it looks.

Where the owner line is
Flush the drain and check the seal and the level before calling anybody. Those three take half an hour and resolve most of these.
