The short version
A ATMSL refrigerator with water under the crispers has a drain problem; one with a wet patch behind it has a plumbing problem. The roster covers five listings, ATMSL181, ATMSL181TH and ATMSL212E, plus the starred variants of those numbers shown in the table below. Those are different repairs, different costs and different urgencies, and a paper towel tells them apart in a day.
How it presents
- Water pooling under the crisper drawers — The signature of a blocked defrost drain on this cabinet type. Meltwater that cannot reach the drain runs forward under the liner instead.
- 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.
- 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.
Likely causes in order
- 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.
- Door seal, door alignment or the door left ajar — Common on cabinets where shelves are overloaded or a drawer no longer closes flush. The water is real but nothing has failed except the seal, which makes it the cheapest genuine finding on this page.
- 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.
- 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: The ranking below moves the defrost drain above the water supply, which is the reverse of the brand-generic order. On the ATMSL roster the drain runs from the coil through the cabinet wall to a pan, and that path glazes over with ice long before any fitting on the supply side works loose.
Diagnostic order on these models
- 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.
- 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.
- 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: Work from where the water is back towards where it came from. On the ATMSL listings there are only three sources, and each announces itself in a different place.
Safety first
Safety
Isolate the unit first - unplug it or switch off its breaker - and remember a capacitor can hold a charge after the power is off. Never clear a frozen drain with a metal probe or a heat gun; warm water poured slowly does the job without puncturing the liner or a coil behind it.
Models in the ATMSL 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 once the drain has been cleared and the water comes back, because a drain that re-ices within weeks is reporting a defrost fault rather than a blockage. On the ATMSL roster that work sits behind the freezer liner. Call immediately if you find an oily film rather than clear water.
