What is going on across the WBV line
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 WBV refrigerator the useful diagnostic order follows exactly that chain, cheapest link first.
Signs you can observe
- The mould holds water but it never releases — Within the WBV family, full cavities that stay full mean freezing or ejection, not supply.
- Production is slow rather than absent — Where WBV models are concerned, halved output usually means temperature, not a failed part.
- Ice cubes are small, hollow or misshapen — Looking at WBV models specifically, a partial fill each cycle points at low pressure or a valve screen starting to block.
- The ice tastes or smells wrong — Looking at WBV models specifically, stale water in a line that has not been used for weeks, or an unlined bin absorbing cabinet odours.
- The mould fills but the cubes come out hollow or small — Where WBV models are concerned, hollow cubes are the classic sign of a compartment that is not cold enough for long enough.
- 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.
Ranked causes on the WBV line
- A closed, kinked or frozen water supply — It leads because the machine cannot make ice out of nothing, and the whole supply chain is checkable without tools.
- A jammed harvest mechanism or ejector — It ranks below supply and temperature because those two produce the misformed cube in the first place. That is the position it takes on this family.
- The bin-full arm or sensor stuck in the full position — A bag of frozen peas resting on the arm stops production instantly and looks exactly like a dead ice maker.
- A failed ice-maker module or its wiring — It comes last because everything above it imitates it perfectly and costs less to rule out. It sits there for WBV models too.
Where to start, and what follows
- Look at the bin-full arm or sensor first — Within the WBV family, anything resting against it reads as a full bin and stops production dead, at zero cost to check.
- Put a thermometer in the freezer compartment — A freezer holds food safely at 0 °F (−18 °C) or below, and an ice maker needs that to cycle properly.
- Check the age of the water filter, if the machine has one — Across the WBV line, a filter past its life is the cheapest cause of small, hollow cubes and then of none.
- Put a thermometer in the compartment overnight — A freezer holds food safely at 0 °F (−18 °C) or below, and a mould needs that to release.
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.

When to call a technician
The owner line here is the bin, the arm, the supply and the temperature. Everything past it is a part in the maker itself, tested with a meter behind a panel. Call sooner if you can see water anywhere near the electrics, because that is an electrical matter rather than an ice one.
