The short answer for these models
A ARU refrigerator that leaks is producing water normally — every refrigerator does — and failing to get rid of it. This family spans a range of model numbers rather than a single cabinet. The ranking below follows the path that water takes on these cabinets, from where it forms to where it ends up.
What you observe
- A musty smell before any water was noticed — Water standing where it should not has been there a while. The smell usually arrives before the puddle does.
- Water appears a day after a manual defrost — Melt water that had nowhere to go: the drain was blocked before the defrost and the defrost simply made the evidence.
- Water on the floor at the back — Points at the back of the machine: the drain tube exit, the evaporation tray, or a supply fitting on a plumbed cabinet.
- Water appears only when the ice maker runs — The fill tube or its connection, not the drain. Timing is the evidence here.
- NEAR MISS — water only in the drip tray at the back, with a dry floor — That is normal. Every refrigerator evaporates its melt water from a tray; a wet tray is the machine working.
Ranked causes for these models
- The water connection behind the cabinet — First on the ARU family whenever the cabinet is plumbed. Fittings loosen when a machine is pulled out for cleaning, lines kink behind it when it is pushed back, and a compression joint that has been disturbed once will weep. The leak is steady, not tied to any cycle, and that is how you recognise it.
- Fill tube and the ice maker connection — Second. Water that leaks at the fill tube appears only while the maker is filling, which makes it intermittent and hard to catch. If the puddle matches the ice cycle, this is where to look.
- Defrost drain — Third. The standard cause of interior water, kept here because on a plumbed cabinet the supply side has to be excluded first — otherwise a clear drain gets blamed for a wet floor it did not cause.
- Condensation from door and seal — Fourth. It is a contributing cause on almost every leak and the primary cause on few of them.
- The pan at the back and how the cabinet stands — Last, and usually found while checking something else — a pan that has been knocked out of position when the cabinet was last moved.
The order to work in on these models
- Watch whether the leak continues with the supply off — A leak that stops is a supply leak. A leak that continues is a drain or a condensation leak. One test, two halves of the list.
- Check whether the puddle tracks the ice cycle — Water that appears only while the maker fills is at the fill tube, not the drain.
- Clear the defrost drain — Now worth doing, and it is the fix for the interior half of this complaint.
- Level the cabinet and reseat the drain pan — Finishes the job and stops the version of this leak that returns a month later.
Before you open anything
Safety
Power off first — a capacitor can hold a charge after the power is off — and water off before any connection is opened. Warm water, not boiling, for clearing a drain; boiling water deforms the channel. If the water has reached an outlet or a power strip, leave the breaker off until everything is dry. If the leak came with a warm cabinet, judge the food by temperature rather than by the puddle: a refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below.

The line between an owner fix and a service call
Call if the leak is at a supply fitting and does not stop when the valve is closed and reopened, or if water has reached the floor structure. On the ARU family clearing a drain, adjusting feet and reseating a pan are owner work; anything that needs the evaporator cover off, or a plumbing joint remade, is not. Call the same day for a leak behind the cabinet, because that one is quietly expensive.
