The short answer
On the Amana ABB refrigerator family, water where it should not be points at the pan under the cabinet, because these units get moved and the pan is the part that gets knocked out of place when they are. The brand-generic article puts a blocked defrost drain at the top of this symptom; on this platform it sits fourth, behind causes that are quicker to rule out.
What you observe on these models
- A stain on the floor that reappears at the same spot — A repeatable location is worth more than any single observation about volume.
- A puddle at the front of the cabinet after each defrost — Water arriving in slugs rather than continuously points at the drain path.
- A wet patch at the back that never fully dries — Something pressurised is weeping, and it does so whether or not anyone uses the machine.
- NEAR MISS — ice on the shelves but no free water — That is a seal or a door-ajar problem rather than a leak.
Causes, most likely first on this family
- Drain pan cracked, displaced or overflowing — Top of the list on these models. The pan under the cabinet is meant to evaporate what the drain delivers. Once it is cracked or knocked out of position by a move, the same water that used to disappear now arrives on the floor.
- Cabinet out of level, so water runs the wrong way — Second. The drain trough only drains downhill. A cabinet tipped forward by a move or a soft floor sends meltwater toward the door rather than toward the outlet.
- Water inlet valve seeping — Third on this platform. The valve holds mains pressure whenever the machine is idle, so a weeping seat leaks around the clock rather than only during a fill. The tell is a wet patch at the back that never fully dries.
- Defrost drain blocked with ice or sludge — Fourth, and the one to rule in only when the others are clean. Meltwater from each defrost has exactly one way out. When the drain trough freezes or silts up, the water backs up under the crisper drawers and finds the floor by the shortest route.
Check in this order, and why
- Look at the pan under the cabinet — Start here. It should be damp, not full and not displaced. A cracked or shifted pan explains a floor leak with a healthy drain.
- Check the cabinet is sitting level and firm on all four feet — Then this. A cabinet tipped forward sends meltwater to the door, and this is corrected with a spanner rather than a part.
- Look at the back of the cabinet where the water enters — Third. A valve that is weeping leaves a patch that is wet whether or not anyone has used the dispenser.
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. A refrigerator is heavy and top-loaded with its doors on. Walk it out rather than dragging it, and have a second pair of hands for the tilt.

When to call a technician
Call once the drain, the filter head and the level are all clean, because what is left is behind the liner or inside a pressurised joint. Call if the cabinet has to come out and you cannot empty it first. A loaded refrigerator on a soft floor is how both floors and backs get damaged.
