The short answer for this line
Water on the floor of an NL unit rarely means the cabinet has failed. The gasket is the whole seal on a cabinet this size, so condensation at the door line ranks ahead of anything internal, which is why the checks below start outside the machine and work inwards. Start with warm air getting past the door or lid seal and leave a split drain hose or a failed seam until everything cheaper has been excluded.
What this looks like on these models
- The leak tracks the weather — Worse on humid days, absent in a dry cold room, with nothing about the unit changed.
- Water appears at about the same time each day — Following a cycle rather than following use, which narrows the cause considerably.
- 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.
- 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
- Warm air getting past the door or lid seal — The leading cause on these models: a seal fault produces water in proportion to how humid the room is, which is why it is reported as seasonal and dismissed in winter.
- The door not latching fully — Second: this differs from a seal fault in that the gasket is fine; the door is simply not closed onto it, so the fix is loading or a hinge adjustment rather than a part.
- A blocked condensate drain path — Third, and worth excluding before going further: the drain outlet in the compartment floor is the only route defrost melt has, and on a compact cabinet it is a narrow one. Food film, a crumb of packaging or a plug of ice narrows it further, the trough fills, and the water leaves at the lowest point of the seal instead.
- A split drain hose or a failed seam — It ranks last for the usual reason: it is rare, and every cheaper cause above it explains the same puddle.
Check in this order, and why
- Test the seal along its whole length — Run a hand round the closed door for a cool draught, then look at the gasket for a flattened section or a fold that has taken a set.
- Watch the door close on its own — Close the door and let go without pushing. It should pull itself onto the seal; a door that stays a fraction open, or that springs back, is the fault.
- 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
Stop and call if the leak needs a panel removed to find, if it recurs after a clear drain and a level stance, or if the cabinet is also failing to hold temperature. The last combination usually means the frost that is melting has a cause of its own.
