The short answer
A leak on a 4w5ij21 refrigerator usually begins as frost you never saw. Where the brand-generic article ranks the water valve first because it must cover plumbed and unplumbed models together, this one ranks the drain path first. Mop the floor and mark the spot before you move anything.
What you actually observe
- Water pooling under the crisper drawers — Pull the drawers right out rather than looking past them.
- A sheet of ice on the freezer floor — It will run as soon as the next defrost cycle melts it.
- A dried tide mark that keeps reappearing — The mark shows you where the water leaves the cabinet, which is not where it started.
- A stale smell from the fresh-food compartment — It often arrives before the puddle does.
Causes on the 4w5ij21 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 short revision run in the table above means these units left the line close together, so they wear at much the same rate.
- An ice maker fill or supply line fault — A valve that fails to close fully keeps filling long after the mould is full. The overflow freezes, builds, and eventually runs out the front.
- A cracked or displaced drain pan — A split pan leaks only when the unit has run long enough to fill it, which is why the puddle seems to come and go. It is the cause that survives every check done from the front of the cabinet.
- A water filter head or cartridge leak — Aftermarket cartridges that are a fraction out of tolerance are a frequent source of this leak. If the leak started with a filter change, start there.
Check in this order, and why
- 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.
- Pull the cabinet out and look at the drain pan — You are looking for a crack, a warp, or a pan sitting off its rails, all of which leak only when the pan is loaded.
- 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. Water and a live appliance do not belong in the same job: dry the floor before you pull the cabinet out, because a wet floor and a heavy unit is how people get hurt. If the puddle reaches a wall outlet or an extension lead, kill the circuit at the breaker before you touch anything.

When to call a technician
The line on these models is whether the water is on the inside or the outside of the cabinet. Inside, it is a drain you can often reach; outside at the back, it is a fitting, a valve or a cracked pan and it needs the unit moved and held. Call if the leak is at the back wall and you cannot see where it starts.
