The short answer first
On the 4w3in62 refrigerator this symptom is usually the defrost drain, which on this platform silts up, freezes at the trap and then sends every defrost cycle onto the floor instead of into the pan. The 4w3in62 family is one platform carried across a run of revisions, and the trailing digits of the model number are what separate them: the fault set is shared, the part numbers are not.
What an owner actually sees
- Frost on the freezer rear wall alongside the water — Two symptoms with one cause: airflow blocked, drain frozen, water finding another way out.
- 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.
- 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 4w3in62 family
- Blocked defrost drain backing up into the cabinet — Top of the list 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.
- Cabinet out of level, tipping condensate the wrong way — Second here. Tipped forward, or sitting on a floor that has moved, the channel that should feed the drain feeds the door instead.
- Dispenser line, reservoir or its fitting behind the liner — Third on this platform. It is the only cause here that produces a leak at the front with the doors shut and no ice involved.
- Ice that built up elsewhere melting during a warm spell — Fourth: possible, but not where to start. Ice from an earlier airflow fault sits harmlessly until a power cut, a door left open or a defrost cycle releases all of it at once.
- Body: A brand-generic article on this symptom starts with the blocked defrost drain, and so does this one.
The order to work in
- 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.
- Put a level across the top of the cabinet front to back and side to side — A front edge sitting lower than the back is enough on its own to deliver water to the front of the machine.
- 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.
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.
