The short answer
A water leak on a WTW refrigerator usually comes down to humid air condensing where it meets a cold surface, which makes the outside of the cabinet as likely a source as the inside. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious.
What you actually observe
- Water runs from the lid line when the lid is opened — Condensate collecting in the seal channel, which is usually a seal or a levelling problem.
- The floor is wet only after the unit has been switched off for a while — Everything frozen inside has thawed, and there was more water in the plate frost than anyone expected.
- Water appears under the unit after it has been moved — Classic pooled meltwater tipping out of the cabinet floor rather than a leaking component.
- Water is dripping while the unit is cold and untouched — NEAR MISS: worth checking the contents and any container inside before treating the cabinet as the source.
- Body: No two WTW listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.
What causes it on the WTW platform, in likelihood order
- 1. Defrost water and the cabinet drain — Owners find this as a leak that only happens on the move. It ranks first on WTW because both listings drain the same way, which makes the drain path the first thing to check on either.
- 2. Humid air meeting a cold surface — Warm air leaking past a tired gasket condenses the moment it touches the cold interior, and the same thing happens on the outside of the shell in a humid room. Second on WTW: it is as common as the cause above it but takes longer to prove, so it is checked afterwards.
- 3. The unit not sitting level — In a vehicle or on a boat this is the usual answer, because the floor is rarely flat and the slope changes with the load.
- 4. A gasket that has been crushed or nicked — A gasket stored clamped for months, or nicked by something in the way of the lid, will hold a line of contact everywhere but one place, and that one place is where the condensation runs.
The order to work in on this platform
- 1. Empty it and look at the drain plug in the cabinet floor — Settles the commonest cause in a minute and with no tools.
- 2. Note whether the water is on the cold side or the warm side — Beads on the outside shell are condensation, not a leak, and that changes everything that follows.
- 3. Put a level across the cabinet, loaded as it normally sits — Water finds the drain only on a level floor, so this is checked before the drain is blamed.
Before you open anything
Safety
Isolate the unit before anything else. Unplug it or switch off its breaker, treat a capacitor as charged after the power is off, and get the cabinet and its lead dry before restoring power. A wet socket on a vehicle circuit is a fire risk long before it is a fridge fault.

When to call a technician
Call when the water is repeatable from the same spot after the drain, the level and the seal are all clean, or whenever it comes from behind the liner. A cracked liner and a leaking sealed system are both outside owner work.
