The short answer first
On the 4w3in40 refrigerator this symptom is usually the water line inside the door and the reservoir it feeds, which are the parts of the water circuit that flex every time the door is opened. Every model number in the 4w3in40 family is the same platform at a different point in its production run, so read your full model number before ordering anything.
What an owner actually sees
- Water under the crisper drawers with a dry floor outside — Water inside the cabinet and none behind it means the drain path, not the supply.
- A puddle that reappears behind the unit after it is mopped — Outside the cabinet and towards the wall points at plumbing or the pan rather than at anything cold.
- Water at the front, in front of a closed door — The door circuit and the door seal both produce this, and nothing at the back of the machine does.
- Ice building in a mound under the ice maker — Water arriving where the mould is not, which is a fill fault and not a drain fault.
- NEAR MISS — water only on top of the fresh food, never on the floor — Condensation on food and shelves with a dry floor is a door-left-ajar or over-full cabinet problem, and no part needs replacing.
Causes, most likely first on the 4w3in40 family
- Dispenser line, reservoir or its fitting behind the liner — Top of the list here. A line rubbed through at a door hinge, or a push-fit that has crept, wets the inside of the door and the floor in front of the machine at the same time.
- Blocked defrost drain backing up into the cabinet — Second here. It is the cause that produces water inside the cabinet rather than beside it, which is the single most useful thing to notice about a leak.
- Ice maker fill tube or fill valve overshooting — Third on this platform. A valve that no longer closes fully lets water past between cycles, and the overflow finds the floor of the freezer before it finds the mould.
- Supply line, shut-off valve or compression fitting weeping — Fourth: possible, but not where to start. It is the version of this fault that has nothing to do with the refrigerator at all, which is why it is worth eliminating early.
- Body: A brand-generic article on this symptom starts with the blocked defrost drain.
The order to work in
- Look at the bottom of the door and the floor immediately in front of it — Water in front of a closed door, with dry floor behind the unit, points at the door circuit rather than at the drain.
- Look for ice or standing water in the channel under the evaporator — Water under the crisper drawers with a dry floor behind the unit puts this at the top of the list every time.
- Look under the ice maker for a growing mound of ice — A mound rather than loose cubes means water is arriving where it should not, and the valve and fill tube are both suspects.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel, and before reaching behind the cabinet to dry a fitting — a capacitor can hold a charge after the power is off.

Where the owner fix stops
Call straight away if water is reaching a socket, an extension lead or the compressor compartment — that is an electrical problem before it is a leak. Anything that needs the rear panel off, the liner opened or the sealed side touched is a service visit on these models.
