The short answer
On the TWW line a puddle is usually a routing problem rather than a broken part: a drain that passes a test pour can still be too slow for a defrost, and that is the leak that keeps coming back. 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
- Beads of water on the outside panels — The outer skin is cold enough to sweat in the room it stands in.
- 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.
- NEAR MISS - water only once, right after a move — A unit laid down or carried warm sheds what it was holding. One puddle after a move is not a fault; a second one is.
What it usually turns out to be, in order
- Melt arriving faster than a marginal drain clears — First here, and by a wide margin: this is the cause that survives a cleaning: the outlet was cleared, the pour test passed, and the leak came back on the next warm day when there was more water to shift.
- Contents damming the drain trough — Second on this line: a full cabinet is packed against the walls, and anything sitting in the trough or pressed to the cold plate stops the melt reaching the outlet. The water then finds the gap at the door.
- 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.
Working order, and the reason for it
- Watch one full cycle rather than one moment — Dry the trough, then look again a few hours later and again the next morning. Water that appears and clears on a rhythm is a drain that is slow rather than blocked.
- Empty the cabinet and look at the channel — Note where the contents were pressed hard against the wall before you unload; frost marks on the plate show where airflow and melt were being blocked.
- 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
Isolate the unit at the plug or the breaker before any panel comes off - a capacitor can hold a charge after the power is off. Mop the floor first: standing water underneath a cabinet you are about to tip or move is how this job hurts people.

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.
