The short answer
On the KID line a puddle is usually a routing problem rather than a broken part: the drain path carries the whole of the defrost melt, so it is where a leak on this line almost always starts. 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
- A blocked condensate drain path — Ranked first on this line: 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.
- Warm air getting past the door or lid seal — Next, and close behind: 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.
- Contents damming the drain trough — Then: packaging is the usual culprit: a bag or a carton settles into the channel, water backs up behind it, and nothing about the machine is faulty at all.
- A split drain hose or a failed seam — Last, and the reason the order matters: once the simple causes are excluded, what is left is a route the water should not have: a hose that has hardened and split, or a seam that has opened. This is the least common cause and the only one on this list that is not owner work.
Working order, and the reason for it
- 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.
- 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.
- Empty the cabinet and look at the channel — Take everything out and look along the floor channel for a bag, a wrapper or a container sitting in it. Then reload leaving the channel and the cold plate clear.
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
Call once the drain has been proven clear, the cabinet proven level and the compartment emptied, and the water is still arriving: what remains is behind a panel. Call straight away if the water is anywhere near the machinery end, if a breaker trips, or if the cabinet is warm as well as wet.
