What is actually going on
On the REF line a leak is the defrost drain until proven otherwise, and this platform puts the trough where a slug of ice can hold the whole melt back for days. On the models listed in the table on this page the trough is reached from inside the cabinet, which keeps the repair on the owner side of the line.
What you observe
- Heavy frost has built up around the door opening — Frost at the mouth of the cabinet is a seal story.
- Flooring in front of the cabinet has started to lift — A slow leak shows in the floor before it shows as a puddle, especially on laminate. The REF line behaves the same way here from one model to the next.
- The floor is wet only behind the machine — A cracked or displaced pan, or a supply line if the cabinet has an ice maker.
- Water appears after a power cut — A partial thaw during the outage produces a one-off leak that needs no repair at all.
- Water is standing under the baskets — Lift them out: a shallow pool in the moulded base is melt backing up rather than escaping.
- NEAR MISS — condensation on the outside of the cabinet — External damp in a humid room is condensation.
- NEAR MISS — the water is soapy or coloured — Anything tinted is not coming from the freezer.
The causes, ranked
- Frequent door openings in a humid room — Ranked first on this platform. A chest freezer in a hot utility room collects far more moisture than its drain was sized for. On the REF line this is the part that is reachable first.
- A defrost control fault — Next most likely. Last, and it produces a different picture: a heavy frost sheet that finally thaws all at once.
- An ice maker supply fitting weeping — Third most likely. Supply-side leaks are constant rather than periodic, which distinguishes them. On these models the panel comes away before anything else does.
- A door gasket that no longer seals — Fourth, and getting rarer. A tired gasket both wets the cabinet and frosts the coil, so it produces two faults at once.
- A cracked or displaced drip pan — Uncommon here. The pan is thin moulded plastic, it takes knocks during every move, and a hairline crack empties it as fast as the melt arrives.
Check in this order, and why
- Establish where the water starts — Paper overnight settles front versus rear without a single tool.
- Check the cabinet is level and not tipped forward — A forward tilt defeats the small fall the trough has. That holds for every model the table on this page lists.
- Check the drip pan at the back — A dry pan with indoor water proves the melt is not reaching it.
- Test the door seal with a sheet of paper — Walk the test round all four sides.
Safety first
Safety
Two hazards: stored charge and weight. Unplug the appliance or switch off its breaker before any panel comes off, and unload a full cabinet before moving it.

When this becomes a service call
Call when the drain has been flushed clear and the cabinet still wets the floor, or when the frost sheet rebuilds within days of a clear-out. The second is a defrost control fault and it is diagnosed behind a panel.
