The short answer
Water under a 4w5ij90 refrigerator is almost never the sealed system; it is condensate that has found a way out of its normal path. The brand-generic page has to cover dispenser lines and ice-maker plumbing that not every listing in this family has, so the order below starts with the drain instead.
What you actually observe
- Water at the back of the cabinet only — A leak that never reaches the front is usually behind the unit rather than inside it.
- The puddle comes and goes on a rhythm of days — A supply leak does not care what the appliance is doing.
- Drips at the dispenser or under the filter head — Water that is under mains pressure drips whether or not the unit is running.
- NEAR MISS — water only when the ice bin is filled — That is an ice-maker fault rather than a leak, and it is covered on its own page.
Causes on the 4w5ij90 listings, most likely first
- A blocked defrost drain tube — Meltwater from every defrost cycle has one route out, and when the tube ices or silts up the water backs into the cabinet and finds the door seal. It is the most common cause on this family by a wide margin. The long revision run above covers a lot of production, and the oldest listings in it reach this point first.
- An ice maker fill or supply line fault — A valve that fails to close fully keeps filling long after the mould is full.
- A door gasket letting warm air in — A gasket that has taken a set is a continuous humidity leak, and the drain is not sized for it.
- A cabinet out of level — These cabinets are designed to sit with a slight rearward tilt so the drain runs the right way; level them flat or forward and it does not.
Check in this order, and why
- Dry everything and find where the water starts — Inside the cabinet, at the back, or under the doors — those three answers point at three different sets of causes.
- Find the drain hole at the base of the freezer wall — Warm water poured down it either runs through to the pan or it does not, and that is the whole test.
- Follow the supply line and the filter head dry — Wrap tissue at each fitting and come back in an hour; a weeping joint will find it faster than your eye will.
- Check the gasket for a section that has lost its grip — Only worth doing once the drain is known clear, because a seal fault shows up as a drain fault.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Shut the water off at the shut-off valve before you disturb any supply fitting, not after. Clear the floor and dry it first: a full refrigerator on wet tile moves in ways it does not on dry.

When to call a technician
Clearing a blocked defrost drain from inside the freezer is owner work; anything that needs the evaporator cover off or the drain heater checked is not. A supply line that leaks at the fitting is a plumbing job rather than an appliance one. Call straight away if water is reaching an outlet, or if the puddle returns within hours of being dried.
