What this means on these models
On the AMAW line the important first question about a leak is not what is broken but whether the water is clean supply water or melt water. Three model numbers carry this family badge, and the matrix on this page is the list. Melt water means the drain path; supply water means a joint, and those two lead to completely different repairs.
What you observe
- A sheet of ice on the freezer floor — The same blockage seen from the other compartment — melt water freezes where it stands before it can drain.
- Water at the front of the floor, usually after a cycle — A puddle that returns hours after being mopped tracks the defrost cycle rather than the supply.
- Water running down the inside of the door liner — Moisture on the liner and shelves means the cabinet is running above its setpoint or the door is not sealing.
- Damp or buckled flooring under the appliance — A slow leak that has been running for a while, which is worth treating as urgent even when the volume looks small.
- NEAR MISS — water only in the drain pan at the back — Water sitting in the drain pan at the back is the defrost system finishing correctly and needs nothing.
Ranked causes for these models
- Supply line, inlet valve or dispenser tubing leaking — First on the AMAW line not because it is the likeliest but because it is the only source here that never stops. A pressurised joint is ruled out first on consequence alone.
- Blocked or frozen defrost drain — Second. If the water only appears after the unit has been running, this is almost certainly it.
- Door seal or a door not closing fully — Third: humid room air condensing inside the cabinet, which looks like a leak but is the appliance doing what physics requires.
- Drain pan cracked or off its seat — Last: uncommon, and it presents as water at the rear after the drain has already been proved clear.
Check in this order, and why
- Shut the household water valve and watch for an hour — First because it separates pressurised water from melt water decisively: a leak that stops is supply, one that continues is not.
- With the water off, look for any remaining wetness at the rear — What is left is the pan or the drain tube rather than a live joint.
- Clear the defrost drain at the freezer floor — With supply excluded, this is where interior water comes from.
- Paper-test the gasket all round both doors — Paper-test both door gaskets last, because a door fault shows on the liner rather than on the floor.
Safety first
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 mix: dry the floor before working, and if water has reached a socket or an extension lead, switch the circuit off at the consumer unit before touching anything. Close the household water valve before breaking any supply joint.

Where owner work stops
Book a technician once the drain is clear, the gasket seals and water still appears, and book one immediately if the leak is continuous rather than cyclical. On the AMAW line the practical line is the liner: work in front of it is an owner job, and work behind it is not.
