The short answer
On the WTW line a puddle is usually a routing problem rather than a broken part: a leak that started after the unit was moved is a level problem until proven otherwise. Two of the likely causes are owner-checkable with nothing but an empty cabinet, and only the last needs a technician.
What the owner actually sees
- A puddle at the front, under the door line — It re-forms within a day of being wiped, and the floor behind the unit stays dry.
- Standing water on the compartment floor — Enough to see, sitting in the channel rather than spread across the base.
- Water only after the unit has been open or switched off — Nothing during normal running, then a puddle after a stop.
- NEAR MISS - ice inside but no water anywhere — That is a frosting fault, not a leak, and it belongs on the freezing and ice pages rather than this one.
What it usually turns out to be, in order
- The cabinet standing out of level — First here, and by a wide margin: level is not cosmetic on a unit this size. A small tilt is enough to move the low point of the floor away from the drain, and then every defrost puts water where the seal is, not where the outlet is.
- 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.
Working order, and the reason for it
- Check that the cabinet stands level and square — Put a level across the top in both directions, or simply pour a spoonful of water onto the compartment floor and watch which way it runs. It should run to the outlet.
- Wipe the outside dry and watch where water returns — Feel the panels: a cabinet that is cold to the touch on the outside in a warm room will sweat, and the fix is clearance and air movement rather than a repair.
- Clear and test the compartment drain — Empty the compartment, find the outlet in the floor, and pour a little warm water at it. If it stands rather than draining, that is the fault and nothing further needs checking.
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 the electrical end of a refrigerator do not mix, so dry the floor and isolate the unit before you kneel down beside it.

Where owner work ends
Two conditions make it a call rather than a check: water that returns with the compartment empty and the drain proven clear, and any water at the electrical end. A third is a leak that has already soaked the base, because wet insulation does not dry out in place.
