Answer first
On a WANAI refrigerator no ice is usually a frozen fill tube or fill cup, not a failed ice maker. The module is the part people blame and the last part that is actually at fault. Most of this you can settle before you book anyone.
The symptoms, and their near misses
- It cycles and fills but the cubes come out small or hollow — Water is arriving, but not enough of it.
- NEAR MISS: water pools under the crisper or on the floor — That is a drain or supply leak and belongs on the water-leak page for this unit.
The ranking: most likely cause first
- A frozen fill tube or fill cup — A slow trickle at the end of the fill freezes in the tube instead of running into the mould. The next fill hits a plug of ice and backs up. Ranked first on this unit: on a cabinet that is opened often the fill end sits in the coldest, wettest air in the appliance, so it is where ice forms first, which counts for more here because this is a compact appliance doing the work of a full-size one, which pushes the parts that are asked for most to the top of the list.
- Water supply shut off, kinked or never fully opened — The saddle valve behind the unit gets closed for a plumbing job, knocked when the fridge is pushed back, or was never opened fully after installation. Next, and for a closely related reason: it is the first thing disturbed whenever the unit is moved, and moving a refrigerator is exactly what happens before this fault appears.
- A failed ice maker module or harness — The motor, thermostat and heater live in one sealed module. Last, and that is the point of this order: everything above it produces the same empty bin for a fraction of the cost.
What to check first, second, third
- Look into the fill tube at the back of the ice maker for a plug of ice — Ice visible there ends the diagnosis on the spot.
- Trace the water line behind the unit and check the valve is fully open — A closed or half-turned valve explains every symptom on this page at once.
- Only once water is confirmed at the mould and the freezer is cold — At that point the module is what is left, and it is a parts job.
What an owner can safely check
- Look at the fill tube where it enters the ice maker and thaw any plug with warm, not hot, water — Never chip ice out with a knife or a screwdriver.
Tools: warm water, a clothAbout 20 min
- Pull the unit out and follow the water line back to its shut-off valve — Open it fully. Check the line is not crushed against the wall.
About 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.
Safety first, and it is not boilerplate
Safety
Pull the plug or drop the breaker before you take off a panel. There is a capacitor in this appliance that stays charged after the power is gone, and the compressor terminals are live whenever it is not. Do not rewire or bypass a door switch to keep a fan running while you look. Refrigerant work is licensed, so the sealed system is a technician's job from the first step to the last.
When to call a technician
Call once water is confirmed arriving at the mould and the freezer is holding temperature, because at that point the fault is inside the module or its harness. Call sooner if you find water anywhere it should not be, or if the unit trips a breaker when the ice maker tries to cycle.

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: module part numbers, fill-volume adjustment, valve resistance figures and any harness pinout, all of which differ by family and belong on the page for that family.
