The version worth reading first
On the ABMZ roster the fear that brings most leak calls in - refrigerant - is the one thing it will not be. The family covers one base number, ABMZ171E, carried twice in the parts data. Refrigerant is a gas at room conditions and leaves no puddle, so clear water is defrost water, supply water or condensation and nothing else.
The observable signs
- A puddle in front of the unit that comes and goes — Intermittent water tracks the defrost cycle. It appears hours after a defrost and is gone by the next morning.
- Sweating on the outside of the cabinet or on the door — A humidity and sealing story rather than a leak. It gets reported as a leak because the water ends up in the same place.
- NEAR MISS - an oily film rather than clear water — Oil in the machine compartment means the sealed system is open. Stop, do not run the unit, and call.
Causes, most likely first on this roster
- Blocked or frozen defrost drain — Ranked first. On cabinets of this type the drain opening sits at the base of the evaporator area where it is both hard to see and easy to glaze, so it is the one cause that reliably outnumbers all the others.
- Door seal, door alignment or the door left ajar — Ranked here because it is free to confirm and because it is upstream of the entry above: the moisture a failing seal admits is the meltwater the drain then cannot carry.
- Drain pan cracked, displaced or overflowing — Placed at this point because a full pan and a cracked pan mean different things: one is a delivery or airflow problem, the other is a failed part.
- Condensation from ambient humidity or a blocked air path — At the bottom because its signature is seasonal: it rises and falls with the weather and with how often the doors are opened, which nothing mechanical does.
- Body: Ordered by what gets found rather than by what owners suspect. Condensation and door sealing sit high because they produce water in the same places as a real leak and cost nothing to rule out.
Check in this order, and why
- Establish exactly where the water appears — Under the crispers, on the floor in front, or at the back low down. Each points at a different system and the three rarely overlap.
- Pull the crisper drawers and look at the liner floor — Standing water under the drawers with a dry floor outside is a blocked drain until proved otherwise.
- Check above and behind the appliance, not just under it — A dripping pipe or fitting above the unit lands behind it and looks exactly like an appliance leak.
- Body: Work from where the water is back towards where it came from. On the ABMZ listings there are only three sources, and each announces itself in a different place.
Before you start
Safety
Dry the floor before you begin and keep it dry: water beside a live appliance is a slip risk and a shock risk at once. Unplug the appliance or switch off its breaker before clearing a drain or removing a panel, and a capacitor can hold a charge after the power is off. Close the water shut-off before touching any fitting.
Models in the ABMZ family — This page generalizes over every listing in the roster below; where the models diverge for this fault the text says so, and where it does not, they behave alike. A starred entry in the table is the same base number recorded a second way in the parts data; treat it as the same platform for this fault unless your own parts diagram says otherwise.

Where the owner line is
Call when a drain that has been cleared blocks again within weeks, because on the ABMZ roster that is a defrost fault reporting itself and the parts for it sit behind the liner. Call the same day for a constant leak: water under a cabinet damages a floor long before anyone sees it.
