The short answer for WCSE models
An ice maker is a small machine bolted into a cold box, and it needs three things to work: water at pressure, a compartment at or below 0 °F (−18 °C), and a working harvest cycle. On an Avanti WCSE refrigerator the useful diagnostic order follows exactly that chain, cheapest link first.
Signs you can observe
- The mould fills but the cubes come out hollow or small — On every WCSE model in the table, the fill is arriving but the freeze is not finishing, which points at temperature rather than at water.
- The ice tastes of the freezer — On every WCSE model in the table, empty the bin and let it make fresh: taste is not a mechanical fault.
- Ice cubes are small, hollow or misshapen — Within the WCSE family, hollow cubes are the classic low-flow signature and they appear long before production stops.
- The ice tastes or smells wrong — On WCSE models in particular, flavour faults are a water and hygiene question, not a mechanism one.
- The mould holds water but it never releases — On WCSE models in particular, full cavities that stay full mean freezing or ejection, not supply.
- NEAR MISS — water on the floor as well as no ice — A leaking fill line produces both. Read the water-leak page for your model line first, because that one is urgent.
What actually fails on WCSE models, in order
- A closed, kinked or frozen water supply — First, because it is the most common and the cheapest: a saddle valve nobody opened fully, or a fill line pinched behind the cabinet.
- A compartment that is not cold enough to freeze — It sits here because a few degrees warm halves production long before anything else shows, and a thermometer settles it. For WCSE models the reasoning is identical.
- A shut-off arm or sensor held up by the ice already in the bin — It belongs here because emptying the bin is free and because it explains a maker that stopped without warning.
- A failed ice-maker module or its wiring — Last: the module itself is the least likely link in the chain and the only one that is a parts-and-labour job. The same order applies across the WCSE family.
What to look at first, second, third
- Look at the bin-full arm or sensor first — Within the WCSE family, clear the bin, make sure the arm swings freely, and give it a cycle before going further.
- Put a thermometer in the freezer compartment — If it reads warmer, the ice fault is a cooling fault and belongs on a different page.
- Check the age of the water filter, if the machine has one — On WCSE models in particular, replace it, run a few litres through to purge the air, and re-test.
- Empty the bin completely and let it refill — Looking at WCSE models specifically, do this before anything else: a fused lump imitates several different faults.
Before you take any panel off
Safety
Power and water both off before you start: a capacitor can stay charged after the power is off, and a pressurised line will spray when you loosen a nut. Work with the machine pulled clear so you can see what you are doing, and dry everything before you restore power.

Where the owner line falls
Hand it over once the arm, the supply, the filter and the temperature are all confirmed good. At that point the remaining candidates are the inlet valve, the module and its harness — all behind panels, all with water and electricity in the same small space. Call sooner if you find any sign of water where it should not be.
