The short answer
On the Cosmo COS refrigerator family an ice complaint is usually a water-supply problem or a freezer that is not cold enough, rather than a failed ice maker: the machine needs water it can actually get and a compartment cold enough to freeze it. The brand-generic article opens on the module; on this model the two upstream causes are both far more common and both cost nothing to check.
What you see on the COS family
- No ice at all and the mould is dry — No water is arriving. That points at the supply line, the valve or a switched-off ice maker rather than at freezing.
- A solid block of ice in the bin instead of cubes — Cubes that partly thawed and refroze, which means the freezer is losing temperature between cycles rather than that the maker has failed.
- Small, hollow or misshapen cubes — Low water flow, usually a partly frozen fill tube or a restricted filter, so each fill is short.
- The maker fills but the cubes never release — Either the compartment is not cold enough to complete a cycle or the mould heater and ejector are not finishing it.
Causes, most likely first on the COS family
- Ice maker switched off, bail arm up or the bin jammed — Ranked first on the COS family — it costs nothing to look at and it is the single most common non-fault behind this complaint on this model. The bail arm or the sensor arm stops the cycle when it reads a full bin, and a bag of frozen food leaning on it reads full forever.
- Water supply, fill tube or filter — Second — it is checkable by eye and it explains a dry mould completely. The supply valve behind the cabinet gets closed during cleaning or a house move, the fill tube freezes shut when the compartment runs cold, and a long-overdue filter throttles the flow.
- Freezer temperature not low enough to complete a cycle — Third — it is the cause behind slow or hollow ice far more often than the module is. An ice maker will not harvest until the mould reaches its release temperature.
- Ice maker module, mould heater or the inlet valve — Fourth — it is the expensive end of the list and the one that needs a technician on this model. The module drives the ejector and the mould heater releases the cubes.
- Body: The order below is this family's rather than the brand's: with one build in the COS family the ranking is not an average diluted by chassis that fail differently, so the cause at the top is the cause that actually leads on COS-24BIWCS.
Check in this order, and why
- 1. Look into the mould before touching anything — Dry, full of water, or full of a frozen block.
- 2. Check the age of the water filter — A long-overdue filter throttles the fill, which shows up as small hollow cubes long before it shows up as no ice.
- 3. Check the ice maker is switched on and the arm is down — A bail arm held up by a bag of peas stops the cycle indefinitely, and nothing about the cabinet looks wrong.
- Body: Because the COS family is one model, the access route below is the access route — there is no second layout to hedge against, which is exactly what the page above this one has to do.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Shut the water supply valve before disturbing any fitting behind the cabinet, and never thaw a frozen fill tube with an open flame or a heat gun: a hair dryer on low or simply switching the unit off is what the job needs.

When to call a technician
Call when there is water at the valve, the compartment is genuinely cold, the arm is down and the mould still never fills or never releases: that leaves the module, the mould heater and the inlet valve, and all three sit behind the cabinet trim on this model.
