What the water is telling you
On the ABMN roster the defrost drain is the fault that produces most leak calls. Meltwater from the coil is meant to run out through a small drain to a pan over the compressor; when that path glazes over with ice the water backs up into the cabinet instead. The roster covers one base number, ABMN171E, carried twice in the parts data.
What you observe
- A steady wet patch at the back low down — Constant water points at the supply line, a compression fitting or the inlet valve rather than at the defrost side.
- A full or overflowing drain pan under the machine compartment — The pan is meant to evaporate what the drain delivers. A pan that overflows means either too much water or too little airflow across it.
- The puddle is worse after a hot day — More humidity in, more meltwater out. A drain that copes in winter can be overwhelmed in summer.
- NEAR MISS - water plus a cabinet that is no longer cold — A warming cabinet defrosting itself makes a lot of water. That is a cooling fault and belongs on the cooling page for this family.
What a technician expects to find
- Blocked or frozen defrost drain — At the top because it is self-reinforcing: a slightly restricted drain freezes a little more each cycle, so the fault accelerates quietly until water appears where nobody expects it.
- Water supply line, fitting or inlet valve weeping — Ranked here because it is the leading cause of floor water while being an uncommon cause of water inside the cabinet. Where the puddle is decides whether this entry applies at all.
- Drain pan cracked, displaced or overflowing — Ranked here because it is quick to confirm once the unit is pulled out, and because the classic trigger is a house move or a kitchen refit rather than age.
- Condensation from ambient humidity or a blocked air path — Last among the water causes because it is a condition rather than a failure, and no part fitted will change it.
- Body: The order here is set by where the water shows, not by the parts list. On the ABMN roster inside-the-cabinet water and floor water lead to different halves of this ranking, and establishing which you have removes the other half.
The sequence that saves time
- 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 the door seals with a sheet of paper — Close paper in the door and pull. Free movement means the seal is not gripping and moist air is entering continuously.
- Body: This sequence is set by access. Everything visible with a drawer out comes before anything that needs the unit pulled away from the wall, and the machine compartment comes last.
Before you start
Safety
Switch the appliance off at the breaker or unplug it before pulling it out to reach the pan, and dry the floor first. A capacitor can hold a charge after the power is off. A loaded cabinet on a wet floor is heavier and less predictable than it looks, so empty it or get help.

When this stops being an owner job
The line on the ABMN listings is the pressurised fitting and the liner panel. Clearing an accessible drain, checking seals, levelling and repositioning a pan are owner work; opening a supply line or reaching a drain heater is not. Stop immediately for an oily film.
