Where the water is coming from
A ABMU refrigerator with water under the crispers has a drain problem; one with a wet patch behind it has a plumbing problem. The roster covers one base number, ABMU171E, carried twice in the parts data. Those are different repairs, different costs and different urgencies, and a paper towel tells them apart in a day.
Where the water is
- 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.
- 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.
- 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.
Ranked by what actually turns up
- 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.
- Drain pan cracked, displaced or overflowing — Also the entry that explains a pan that is simply full: if airflow across the machine compartment has been reduced, evaporation stops keeping up with delivery and the pan overflows with nothing broken.
- Ice maker fill tube or valve dribbling — On this roster the fill path crosses cold space, so a slow dribble freezes before it runs, which is why this fault usually presents as ice first and water second.
- Condensation from ambient humidity or a blocked air path — Not a leak at all in the mechanical sense. In a humid kitchen a cold cabinet sweats, and shelves packed against the rear vents create cold spots that do the same thing inside.
- Body: This ranking assumes the water is clear. If it is not - if there is an oily film in the machine compartment - none of this applies, the sealed system is open and the cabinet should be stopped rather than diagnosed.
Work through this in order
- 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.
- Look for ice on the freezer floor — Ice building at the base of the freezer compartment is the same blocked drain caught one stage earlier.
- Smell the water — Stale water has been standing. Fresh water has arrived recently. It sounds crude and it genuinely narrows the timeline.
- 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.
Safety first
Safety
Unplug the appliance or switch off its breaker before working inside the cabinet, and close the water shut-off before touching any fitting. A capacitor can hold a charge after the power is off. A supply line loosened under pressure empties onto the floor faster than it can be stopped.
Models in the ABMU family — Every listing this page generalizes over. Check the number on your rating plate against it before ordering a part. 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.

When to call a technician
Call when the timing says drain but clearing it from the cabinet side has not worked, because that usually means ice further down the path where a heater rather than a probe is needed. Call straight away for an oily film in the machine compartment - that is the sealed system, and it is licensed work.
