Answer first
A leaking WAA is most often a blocked or frozen defrost drain. Nothing on this list needs a plumber, and only one of them needs a technician. Start by working out where the water appears, because that alone removes half the list.
What you are looking at
- Ice forms as a sheet under the drawers and melts later — The drain froze first and then thawed, which is the same fault seen twice.
- Water appears only after a defrost, then stops — That timing is diagnostic: the drain path is the suspect.
- NEAR MISS: the cabinet is also warm — Then a drain leak is a symptom of a cooling fault, and the cooling page is the right one.
The ranking: most likely cause first
- A blocked or frozen defrost drain — Every frost-free unit melts ice on a cycle and sends the water down a drain to a pan on the compressor. Blocked with debris or plugged with ice, that water goes into the cabinet instead. It leads the list on a WAA refrigerator because it is the one fault that explains water inside the cabinet, and water inside the cabinet is what most owners are actually looking at.
- A door seal letting humid room air in — Warm air reaching a cold surface condenses. Next, and for a closely related reason: on a cabinet in a kitchen that is cooked in, humidity is the water source and the seal is the only thing holding it out.
- A cracked, displaced or overfull drain pan — The pan under the unit is meant to hold meltwater until the compressor heat evaporates it. Third: it is the part that gets knocked whenever anyone cleans behind the unit, and nobody ever looks at it afterwards.
- An ice maker overfilling or its fill tube leaking — A valve that does not close fully, or a fill tube that has worked loose, drips continuously into the freezer. Bottom of the list, deliberately: it explains a leak that gets worse rather than better, and it is the only cause here that is also making a mess inside the freezer.
What to check first, second, third
- Look for ice or standing water under the crisper drawers — Water inside the cabinet is a drain fault until proven otherwise.
- Test the seal with a sheet of paper all the way round the door — Free slide anywhere means a gap and a steady supply of moisture.
- Unplug the unit and look at the pan behind the kick plate — Displaced or cracked is visible at a glance.
What an owner can safely check
- Empty the bottom of the cabinet, find the drain hole at the back of the freezer floor and flush it with warm water — A turkey baster is the right tool. Never push wire into the hole.
Tools: warm water, a basterAbout 30 min
- Close the door on a sheet of paper at several points and check for drag, then clean the seal face — A soiled seal and a set seal look the same and only one of them is free to fix.
Tools: a sheet of paper, warm soapy waterAbout 15 min
- STOP HERE if the fault is on the sealed system — Refrigerant is licensed work and the tools for it are not owner tools.
Before you open anything
Safety
Water and electricity are together in this fault, which is the one thing that makes it urgent. Unplug the refrigerator or switch off its breaker before pulling the unit out or removing the kick plate, and dry the floor before you kneel on it. Shut the water supply off before you touch any fitting. Never push wire down a defrost drain and never thaw one with an open flame.
The line between a fix and a service call
Call if water is reaching the compressor compartment or the unit trips a breaker, and stop using it until someone has looked at it. Call as well once the drain is clear, the seal is good and the line is dry, because what is left is behind a panel.

Scope of this page, and where to go for more
This page covers the WAA refrigerator as a class, not one family or model line. Where a family- or model-specific page exists it is linked here. Deliberately not here: drain heater part numbers, valve flow figures and any panel removal sequence, all of which differ by family and belong on the page for that family.
