Start here
A leak on the ATB line is answered by where the water sits before it is answered by what failed. The matrix on this page is the definitive list for this family: thirty-eight model numbers. Water under the crispers is melt water that could not drain; water at the back with the supply live is a joint; moisture on the liner is the door.
What you observe
- A sheet of ice on the freezer floor — Ice under the bottom basket builds in layers, one defrost cycle at a time.
- A steady drip at the back, near the floor — A slow drip at the rear near floor level that keeps going whether or not the unit has just cycled.
- Water running down the inside of the door liner — Droplets on the shelves and running down the inside of the door, which is condensation rather than plumbing.
- 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.
Causes, most likely first on the ATB line
- Blocked or frozen defrost drain — First here because this is a long-lived family, thirty-eight model numbers deep — a drain that cannot clear is the origin of the large majority of interior water, and it is the same mechanism across the whole table below.
- Door seal admitting warm humid air — Second: a gasket that has taken a set loads the cabinet with moisture, which appears as condensation on the liner and as extra water the drain has to handle.
- Supply or dispenser line joint weeping — Third: clean water at the back of the unit, continuing whether or not the unit has just run, which separates it from melt water at a glance.
- Cracked or displaced drain pan — Last: the pan itself rarely fails, and when it does the water arrives at the back rather than inside the cabinet.
The check order on these models
- Clear the bottom of the cabinet and find where the water actually collects — Under the crispers is the drain, at the back is the pan or a joint, on the liner is condensation.
- Check the drain outlet at the back of the freezer floor — With the bottom basket out, a drain hole that is iced over or silted shut is visible, and clearing it is the repair.
- Run a strip of paper round each door seal — A leaking door is what overloads a drain, so clearing one without the other buys a few months.
- Pull the unit out and look at the pan and the supply joints — Last: it needs the appliance moved, and it is the check that matters only if the interior sources come back clean.
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.

The service-call line
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 ATB line the practical line is the liner: work in front of it is an owner job, and work behind it is not.
