The short answer
Ice production on WHS cabinets depends on three things in series: water reaching the mould, the compartment being cold enough to freeze it, and the harvest mechanism clearing it. The table on this page covers a small group of model numbers in the same line. Almost every complaint on this family resolves to the first two, which are checkable without opening anything.
What an owner actually sees
- Ice arrives slowly and the bin never fills — Production that is merely slow is usually a temperature story — the compartment is not cold enough to complete a cycle in the time the control allows.
- No ice at all, and the mould is dry — A dry mould means water never arrived. That moves the whole diagnosis upstream to the supply, the valve and the line.
- The bin fills far more slowly than it used to — A rate change rather than a failure. It usually tracks the compartment temperature or a partly restricted fill.
- Cubes are cloudy or have a white core — Mineral content and a fast freeze rather than a fault. It says more about the water supply than about the machine.
- NEAR MISS — water on the floor rather than in the mould — That is a supply-line or fill-tube leak and belongs on the water-leak page for this family.
Causes, most likely first on the WHS line
- The supply side: tap, line and connection — First on the WHS family, and by a wide margin. A supply valve left half-closed after a move, a saddle valve that has silted up, or a line kinked behind the cabinet all produce a dry mould and no fault code of any kind. It is also the only cause here that can be confirmed without touching the machine.
- Water inlet valve or a frozen fill tube — Second, because it is the boundary between the plumbing and the machine, and it fails in a way that mimics both. A valve that will not open gives a dry mould; a tube that is partly iced gives a hollow cube.
- How cold the ice compartment actually is — Third. An ice maker will not complete a cycle if the mould does not reach its release point, so a compartment running warm produces slow ice rather than none. On this family that is worth measuring before condemning any part.
- Harvest mechanism and shut-off arm — Fourth. The mechanism is the part everyone blames and the part that is right most of the time — it sits here because three cheaper explanations come first.
- Control or module electronics — Last. A control fault is diagnosed by ruling out water and temperature, and it is the only item here that usually needs a meter.
The order to work in on these models
- Measure the freezer compartment before anything else — A freezer holds food safely at 0 °F (−18 °C) or below; above that, the ice complaint is a symptom of something larger.
- Check that air is reaching the ice compartment — A package blocking the duct starves the mould while the rest of the freezer stays solid.
- Look in the mould for water — The mould state divides supply faults from temperature faults in one glance.
- Watch one full cycle before suspecting the module — A module that completes a cycle when the mould is cold is not the fault, whatever else is wrong.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel or pulling the ice maker — a capacitor can hold a charge after the power is off. Sharp metal edges sit inside the ice compartment on cabinets of this build, and the mould release can be hot immediately after a harvest cycle. Ice that thaws and refreezes is a temperature warning, not just a nuisance: a freezer holds food safely at 0 °F (−18 °C) or below, and fused cubes say the compartment is not holding it.

The line between an owner fix and a service call
Call once the free checks are done — bin cleared, arm reset, supply confirmed, temperature measured — and the maker still does nothing. Bring those four answers to the call and the visit is usually one trip. On the WHS family the module is the last thing to suspect and the first thing owners replace, which is why the order above exists.
