The short answer for this family
On the Alpicol RTW family, an ice maker making no ice, or bad ice is usually the fill valve and the supply behind it. One model in the family means the matrix cannot narrow anything for you, so the order below runs from what costs nothing to check to what costs a visit. The brand-generic article for this symptom ranks the shut-off arm or bin sensor left in the off position first; on this platform it does not.
What you observe on these models
- Which of the family's models you are standing in front of — The matrix on this page is one model, so there is no variant question to answer, and that is worth reading first, because one model in the family means the matrix cannot narrow anything for you, so the order below runs from what costs nothing to check to what costs a visit.
- The mould is dry and nothing has filled it — Water is not arriving. That is upstream of the ice maker and usually upstream of the appliance.
- Cubes are small, hollow or misshapen — Some water is arriving but not enough, or not for long enough.
- The bin holds one fused block rather than cubes — Ice that has melted slightly and refrozen has bridged, and a bridged bin stops the ejector.
Causes, most likely first on the RTW family
- The fill valve and the supply behind it — Ranked first because one model in the family means the matrix cannot narrow anything for you, so the order below runs from what costs nothing to check to what costs a visit.
- The shut-off arm or bin sensor left in the off position — Second. The machine compartment is at the rear base of the cabinet, so the arm is easy to catch and easy to miss.
- A compartment that is not cold enough to make ice — Third. Confirm it with a thermometer before touching the ice maker at all.
- A jammed mould, arm or ejector — Fourth. Worth clearing before parts are considered.
- A sealed-system or compressor fault — Last, and that placement is the point of the ranking: it is the least common cause and the only one that is not an owner fix.
- Body: This is not the brand-generic ranking. The fill valve and the supply behind it moves to the top of this family's ranking and the shut-off arm or bin sensor left in the off position goes down to second place, because the platform here is a single compact build with one cooling circuit.
Check in this order on these models
- Check that water is reaching the machine at all — Follow the line back to its valve and confirm the valve is fully open.
- Look at the shut-off arm or the bin sensor first — Arm up, or a box sitting in the sensor path, and the maker is being told to stop.
- Measure the compartment with a thermometer — A freezer holds food safely at 0 degrees Fahrenheit, or minus 18 degrees Celsius, or below.
- Empty the bin completely and look at the mould — Bridged ice locks the ejector. Clear it, and see whether the next cycle produces loose cubes.
- Body: The order follows the ranking, and the access decides the rest: on these models the machine compartment is at the rear base of the cabinet.
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. Turn the water supply off at its valve before touching a fitting. Never chip at ice in the mould with a screwdriver or a knife: the mould and the heater under it puncture easily, and a punctured mould turns an ice fault into a replacement.

Where the owner limit falls on these models
Call when water reaches the machine, the compartment holds 0 degrees Fahrenheit, or minus 18 degrees Celsius, the bin is clear and the mould still does not fill or eject. Call sooner if the compartment is not holding temperature at all, because then the ice maker is the messenger rather than the fault. On this family the line falls where the access does: the machine compartment is at the rear base of the cabinet.
