The short answer
Short version: most refrigerator leaks are the appliance's own defrost water taking a wrong turn. Start with a defrost drain line packed with ice or debris. If the water is clean, cold and continuous, close the supply valve first and treat it as plumbing.
The symptoms, and the ones that mean something else
- Water pooling under the crisper drawers — The classic blocked-defrost-drain signature: water that should have run to the pan backs up into the lowest point of the fresh-food compartment.
- Damp at the door edges or sweating on the outside of the cabinet — Condensation rather than a leak — the cabinet is meeting humid room air somewhere it should not.
- A sheet of ice across the freezer floor — Defrost water freezing where it stands means the drain opening below it is blocked.
- NEAR MISS — the floor is wet only when the dispenser is used — Spillage and drips at a dispenser are a use problem rather than a fault, and no part will fix them.
Causes, most likely first on a l2 refrigerator
- A defrost drain line packed with ice or debris — Every frost-free refrigerator melts its evaporator frost on a schedule and drains the water through a small tube to a pan above the compressor. That tube is narrow, cold and easily blocked by food debris or by ice forming in its own mouth. Once it blocks, the water goes wherever gravity takes it. First, because nothing else on the list explains as many of these calls, and ruling it out costs nothing but a few minutes. Documentation is thin on a brand like this, so the ranking leans on what can be observed directly rather than on a schematic.
- Drain pan cracked, dislodged or overflowing — It is also the one component in this system that is routinely disturbed: it comes out for cleaning, and a pan refitted a few millimetres proud spills every time the compressor warms it. It follows the first because the two produce the same complaint, and this one is the cheaper of the pair to eliminate.
- A gasket that no longer seals, so the cabinet sweats — The tell is that the water arrives with other complaints — more frost, longer run times, food spoiling in the door — because all of them come from the same leak of warm air. It ranks third: real, but rare enough that chasing it first wastes an afternoon.
- Mains water escaping behind the cabinet — This cause is the one with real consequences for the room rather than for the appliance, which is why it is worth identifying early even though it is less common than a blocked drain. Last, and deliberately so — it should be where a diagnosis ends rather than where it starts.
What to check first, second, third
- Check under the crisper drawers for standing water — Water at the lowest point of the fresh-food compartment with a dry floor behind the cabinet means the drain, not the supply. Begin with this one; everything after it depends on what you find.
- Remove the base grille and look at the pan while the unit runs — A pan sitting proud of its clips, or one with a visible crack, settles the question on the spot. Next: it confirms or clears the cause ranked second, and needs nothing but light.
- Shut the door on a sheet of paper at several points and pull — Paper that slides out easily marks the leak path, and the wet patch inside usually lines up with it. Last of the owner-side checks; anything past it belongs to a technician.
What you can do yourself
- Empty the freezer floor and pour warm water slowly into the drain opening — Repeat until it runs freely; never push anything metal or sharp down the tube.
Tools: warm water, turkey baster or funnel, towelsAbout 40 min
- Adjust the levelling feet so the cabinet sits firm with a slight backward tilt — It helps the doors close on their own as well as keeping the pan level.
Tools: adjustable spanner, spirit levelAbout 25 min
- Check the door closes squarely and is not held open by the load — A door standing proud by a few millimetres produces exactly this water.
About 15 min
- STOP as soon as the fault is narrowed to a part rather than a condition — Naming the part is the useful outcome of an owner check. Fitting it is the other half, and it is not the same job.
Before you open anything
Safety
Switch the power off at the plug or the breaker before anything comes apart, and leave it off while you work. A refrigerator carries a capacitor that holds a charge after the power is off, and the door switch is there to cut the fan for a reason — never defeat it to keep the light or the fan running while your hands are inside.
When to hand it over
The line is at the evaporator cover and at any joint under mains pressure. Before it, warm water and a cloth solve most of these; past it, the panel comes off and that is a technician's work.

What you are reading is written for the class, not for one l2 model. A family- or model-specific page, where one exists, carries what this page cannot: the exact part numbers, the board layout and the disassembly order for that line. Go there first if your model is named.
