The short answer for these models
A AU refrigerator that leaks is producing water normally — every refrigerator does — and failing to get rid of it. This family is one model number, which makes the scope of this page unusually clear. The ranking below follows the path that water takes on these cabinets, from where it forms to where it ends up.
What you observe
- Water on the floor at the front — It has run forward along the cabinet base. On these models that usually means the drain tray or the drain path rather than a supply connection.
- 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.
- Damp only in the bottom drawer, nowhere else — Condensation collecting at the coldest, least ventilated point in the cabinet rather than a drain fault.
- A sheet of ice under the drawers rather than water — The same blockage in a colder cabinet. It freezes where it collects, and it will thaw into a floor leak the moment the machine is switched off.
- 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.
Causes, most likely first on the AU line
- The water connection behind the cabinet — First on the AU line 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.
- The drain path from the evaporator — Third. It stays high because it is common and cheap to clear, but on this family it is second to the supply when the water is on the floor rather than under the drawers.
- 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.
Check in this order, and why
- Find out where the water is, precisely — Under the drawers, at the front of the floor, at the back, or on the inner walls. Each answer eliminates most of the list.
- Note when it appears — After a defrost cycle, on humid days, or continuously. Timing separates drainage from condensation from a supply leak.
- Clear and flush the defrost drain — Warm water and a soft line, never a tool. This one step ends most interior leaks on these cabinets.
- Check that the cabinet is level and the pan is in place — Done after the drain because a clear drain with a displaced pan gives exactly the same puddle.
- Inspect the supply fittings if the cabinet is plumbed — Last in the sequence but first in urgency if the floor behind the machine is damp.
Safety first
Safety
Isolate the cabinet at the plug or the breaker before working, especially with water on the floor. Close the water shut-off before a fitting is disturbed. Mop the floor before moving the machine, because a loaded refrigerator on a wet floor moves further than expected and these cabinets are heavy enough to need two people. Water alone does not spoil food, but a drain that has been blocked for weeks is not clean. Discard anything that has been sitting in the pooled water and clean the base before reloading.

The line between an owner fix and a service call
The line is the evaporator cover. A drain cleared from inside the cabinet with warm water, a levelling adjustment and a seal check are all owner-side on these models; a drain that is blocked above the cover, a cracked channel or a defrost heater fault needs the cabinet opened and a meter. Call immediately if the leak is electrical in location rather than in cause.
