The short answer
On an AZB cabinet a puddle usually starts as frost you never saw. The generic Amana answer covers ice makers and dispensers that this family does not have, so the order below is shorter and more specific. Look inside before you look underneath.
What you actually observe
- Water pooling in the bottom of the cabinet — Take the bottom basket right out.
- A slab of ice under the bottom basket — Water freezing before it reaches the drain builds up in layers.
- The puddle appears every few days rather than continuously — A leak tied to the defrost cycle has a rhythm.
- NEAR MISS — water only after a manual defrost — Use a tray under the cabinet next time rather than trusting the trough with it.
Causes on the AZB listings, most likely first
- A blocked defrost drain — On the frost-free listings every defrost cycle produces meltwater with one route out, and a trough that has silted or iced up sends it forward instead. A plugged drain gives water inside first and on the floor second. This family is a single listing, so what is true of it is true of every unit carrying the badge.
- A door seal letting warm air in — A gasket that has taken a set is a continuous humidity leak, and every defrost cycle then sends a larger slug down the trough. Fix the seal and the drain usually copes again.
- A cabinet out of level — Out of level, the water tracks along the liner and leaves at the door. Check it with a level rather than by eye.
- Meltwater from a manual defrost overwhelming the trough — Heavy ice released all at once runs faster than the drain can take it.
Check in this order, and why
- Dry everything and find where the water starts — Inside, at the back, or under the door: three answers pointing at three different causes. Do it before moving the cabinet.
- Find the drain opening and pour warm water down it — It either runs through or it does not, and that is the whole test. Nothing sharp goes in the tube.
- Check the gasket all round with a strip of paper — Do this once the drain is known clear, because a seal fault imitates a drain fault exactly. Test it at several points around the door rather than at the one that looks worst.
- Pull the cabinet out and look at the pan — Last, because it is the only step that needs the unit moved, and because everything above it is more likely. Check the tube ends over the pan.
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. Empty the cabinet before moving it rather than walking it out loaded. Never chip ice out of a drain trough with a metal tool; warm water is slower and it does not puncture anything.
Models in the AZB family — A single listing: there is no revision spread on this family to account for. A masked suffix in a listing covers the colour and trim variants of that model.

When to call a technician
Clearing a drain, correcting a seal and re-levelling the cabinet are all owner jobs and between them they fix most of these. A drain heater, a cracked inner liner or a pan that needs the unit stripped is not. Call if the leak returns within days of a drain being cleared, because that is a heat problem rather than a blockage.
