The short answer
Water inside or under the A line is usually meltwater that has lost its way rather than a burst pipe. A blocked defrost drain is the leading cause by a wide margin: the water that should run to the drain pan backs up, freezes, and then appears under the crisper or on the floor. The fill line and the filter head account for most of the rest. The name covers a broad group of numbers, so the ranking below holds across the group while the parts stay specific to the machine in front of you.
What you observe on these models
- Drips down the inside of the freezer back wall — Defrost meltwater running where the drain trough is iced, which will reach the floor eventually.
- A wet patch that returns hours after being mopped — A slow leak on the drain path rather than a spill, and the interval between mopping and return is roughly the defrost interval.
- Water pooling under the crisper drawers — The classic blocked defrost drain: meltwater has nowhere to go and backs up into the lowest part of the cabinet.
- A sheet of ice under the freezer floor panel — The same blockage seen earlier — the water freezes where it stands before it ever reaches the drawer above.
- NEAR MISS — water only when the dispenser is used — That is a dispenser or a line fitting, and it is a different and simpler job than a drain blockage.
Causes, most likely first on the A line
- Fill line, inlet valve or filter head leaking — First, and the cheapest to rule out. This is the only water in the machine that is under mains pressure, so a fault here wets a floor quickly rather than slowly.
- Blocked defrost drain or an iced drain trough — Next most likely on these models. It ranks first because it accounts for more refrigerator leaks than everything else combined, and because the fix needs warm water rather than parts.
- Cracked or overflowing drain pan — Third — worth checking once the two above are clean. It ranks where it does because it is easy to check once the machine is pulled out and impossible to see until it is.
Check in this order, and why
- Pull the cabinet out and dry the fittings at the back — Leave it an hour and look again. Only a pressurised fitting wets itself with the appliance standing idle, so this test separates plumbing from meltwater.
- Find the drain hole at the base of the freezer compartment — Empty the freezer, lift the floor panel, and clear the trough and the hole with warm water. Ice in the trough with water above it confirms it outright.
- Look at the drain pan above the compressor — It should hold water without a crack and without overflowing. A pan that is dry with water on the floor means the water never reached it.
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. Leave the sealed refrigerant circuit alone: it is licensed work, and a line opened by accident turns a small repair into a replacement.

When to call a technician
The line on the A line is the freezer floor panel. Above it — drain hole, trough, gasket, shelves — is yours. Below it, and anywhere on the sealed system or the pressurised water line, is a service call. If the leak is at a push-fit fitting behind the cabinet, shut the supply valve first and leave it shut until it is repaired.
