The short answer
Water around an AFU cabinet is almost always ice that has melted somewhere it was not meant to, not a burst pipe. An upright sheds its defrost ice as sheets, faster than any drain was designed to take. That makes this one of the better faults to work through at home, provided you establish where the water starts before you move the cabinet. There is one number under the AFU label in the table below, so nothing here depends on which variant you own.
What you observe on these models
- A sheet of water arriving at once rather than a trickle — Manual defrost releases its ice in slabs.
- More water on humid days than on dry ones — Condensation is weather-driven; a real drain blockage is not.
- Water under the front of the cabinet near the drain plug — The plug is the only deliberate hole in a chest and it is the first thing to check.
- The outside of the cabinet is beaded with water in a humid garage — Sweating shell, dry interior: not a leak at all.
- NEAR MISS — water appears only after a long power cut — That is the load thawing, not a leak.
Causes, most likely first on the AFU family
- Defrost meltwater beating the channel and the drain — First on this platform: on a manual-defrost upright the ice lets go as sheets and arrives faster than the drain can take it.
- A blocked drain hole or channel at the back of the cabinet floor — Second: freezer debris plugs it, and then the water runs forward under the bottom basket.
- Cabinet out of level — Third: the whole drain path assumes a level floor.
- Condensation on the cabinet shell in a humid room — Fourth: it looks exactly like a leak and comes from the room.
- The lid gasket letting warm damp air in — Last: warm air reaching a freezing surface leaves water as well as frost.
Check in this order, and why that order
- Ask when the water appears — All at once after a defrost is the platform working as designed; daily and steady is a drain or a seal.
- Clear the drain hole and channel with warm water — Never a wire: a punctured liner ends the cabinet.
- Look for frost concentrated at one corner of the door — That corner is where the humid air is getting in.
- Level the cabinet front to back — The drain path is designed around it.
- Dry the cabinet shell and watch it for a day — If the shell re-wets with the interior dry, you are looking at condensation from the room.
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. Treat that as the first step of every check below that involves a panel, a grille or a cover.

When to call a technician
Clearing a drain, closing a plug, levelling a cabinet and fitting a gasket are all owner jobs on a upright freezer. On these models the line falls at the sealed refrigerant circuit and the compressor. Call without working through anything at all for a cabinet that has stopped holding despite a clean seal and a clear frost line.
