What this usually is
The usual cause on this unit is a door seal letting humid room air in, with a weeping water line or a loose fitting next. Where the water lands tells you which of the two you have. Start by working out where the water appears, because that alone removes half the list.
What you actually observe
- Water is at the back of the unit, near the floor — That is the pan or the supply line, not the drain.
- 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.
Causes, most likely first on this unit
- A door seal letting humid room air in — Warm air reaching a cold surface condenses. A seal that has taken a set, or a door held ajar by a shelf, keeps a slow supply of moisture going into the cabinet all day. It leads the list on a WANAI refrigerator because 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 weeping water line or a loose fitting — The plastic line to the ice maker and dispenser runs behind the unit and is crushed or nicked when the fridge is pushed back. Second: it is the part of the appliance that is disturbed every time the unit is moved, and a slow weep takes days to become visible.
- 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. Last on purpose: 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.
The order to check in
- 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.
- Pull the unit out and run a dry hand along the water line and its fittings — A weep leaves a mineral trail even when it is dry at the time.
- Look at the freezer floor for a slab of ice under the ice maker — Ice there means the fill is not stopping when it should.
What an owner can safely check
- 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
- Shut the water off, pull the unit out and check the line and every fitting for damp or mineral crust — Look where the line passes the cabinet edge: that is where it gets crushed.
Tools: a torch, a dry clothAbout 20 min
- STOP HERE if the fault is on the sealed system — Refrigerant is licensed work and the tools for it are not owner tools.
Safety first, and it is not boilerplate
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.
Where an owner check ends
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.

What this page does not cover
This page covers the WANAI 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.
