The short answer
This line is a close pair of models rather than a spread, so the build is effectively uniform and the seal-and-fit causes come forward. That is why, on the AZB models, this complaint comes back to a filter head or filter seal weeping before anything else — and why the order below departs from the brand-generic one.
What you observe
- A puddle on the floor in front of the cabinet — Which is a different fault from water inside, and it splits the list immediately.
- A trail of ice down the back of the ice bin — Spill from the fill that freezes on the way down.
- NEAR MISS — a slow drip from the water dispenser tray — A dispenser that drips after each use is a dispenser question, not a leak in the cabinet.
Causes, most likely first on the AZB line
- A filter head or filter seal weeping — Ranked first here — it is the one fitting inside the cabinet that gets disturbed regularly, which is when seals fail.
- A cracked or displaced drain pan — Second here — a pan only overflows once the water has already got that far.
- Condensation in an overloaded crisper — Third here — the water is normal in origin, but it is worth naming so nobody strips a drain over damp lettuce.
- Body: Two closely related models means what holds for one holds for the other, which is why the order below is stated without a hedge. The build does not reorder this particular set of causes, so what you have below is the general order, stated for these models.
Check in this order, and why
- Dry the filter housing completely and look again an hour later — A filter fitted a shade off-seat, or an O-ring left behind by the old cartridge, will show as a bead.
- Slide the pan out from under the cabinet and look at it in the light — A hairline crack in a pan holds water until it is moved, which is why this is a look rather than a touch.
- Note whether the water is only ever inside a drawer — Produce releases moisture; a drawer packed tight and set to high humidity will hold it.
- Body: Two closely related models share a layout, so a check that works on one works on the other and the order below does not change between them. The checks below are in the same order as the causes above them, so a clean result sends you one step further down rather than back to the top.
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. Water and an electrical appliance are a bad pair: dry the floor before you pull the cabinet out, and never work on a wet floor with the unit plugged in. Shut the water supply off at its valve before touching any fitting, and do not clear a drain with a metal probe.

When to call a technician
Call when the water is coming from a fitting you cannot reach dry, when the drain will not clear with warm water, or when the interior floods again within a day of being cleared. Call at once if water is reaching wiring or a socket — that stops being a leak and becomes an electrical fault. Of the causes listed above, most are owner checks and the last is not — that is the line.
