The short answer for this line
Water on the floor of a KM unit rarely means the cabinet has failed. Establish where the water begins before anything else, because a wet floor under the machinery end and a wet compartment floor are different faults, which is why the checks below start outside the machine and work inwards.
What this looks like on these models
- Contents at the base sitting in water — Labels soften and packaging swells while everything higher up is dry.
- A wet gasket all along one edge — The seal line itself is beaded, which points at where the warm air is getting in.
- The leak tracks the weather — Worse on humid days, absent in a dry cold room, with nothing about the unit changed.
- NEAR MISS - the cabinet is warm as well as wet — Water plus a cabinet that will not hold temperature is a cooling fault first; the water is a symptom of it and the cooling page covers it.
Causes in likelihood order on this platform
- An overfull or displaced evaporation tray — First here, and by a wide margin: the giveaway is a dry compartment and a wet floor under the machinery end of the cabinet. Nothing inside is wrong at all.
- Condensation on the outside of the cabinet — Second on this line: a cold cabinet in a warm humid room sweats on its outer skin, and that water runs down to the floor exactly as a leak would. Nothing has escaped from inside the unit.
- A blocked condensate drain path — Third: a restricted drain does not stop the water, it delays it. The melt pools where it cannot be seen, then arrives all at once as a puddle that looks far bigger than the fault behind it.
- A split drain hose or a failed seam — Last on the list, and the only one here that is not owner work: a failed seam leaks the same amount whatever you do to the drain, which is what separates it from everything above. It is also the fault that wets insulation, so it gets worse rather than staying level.
Check in this order, and why
- Look underneath at the machinery end — Wipe the floor dry, run the unit for a few hours, and see whether the new water is under the machinery end or under the door.
- Wipe the outside dry and watch where water returns — Dry the whole outer surface, wait an hour and look again. Water reappearing evenly across the panels is room humidity, not a leak.
- Clear and test the compartment drain — With the unit emptied, look for standing water in the trough before you touch anything. A trough that is wet while the plate is dry means the outlet, not the seal.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and a wet floor makes any contact with the machinery end worse. Never run a lead across a damp floor while you work.

The line between a fix and a call
The line is the panel. Everything you can reach with the compartment empty is owner work; anything that needs the back or the base off is not, because the machinery end holds both the electrics and the sealed system. A wet unit that trips protection is a call, not a check.
