The short answer
An ice maker that has stopped producing on the Alpicool K family points first at water not reaching the ice maker. The order below is this family's own, and it is not the order the brand-generic article sets out. Most of what follows can be settled without opening anything; only the last item is a service call.
What you observe
- Cubes are small or hollow — Partial fills point at flow rather than at freezing.
- A single cube has welded itself to the mould — One stuck cube stalls every cycle that follows it.
- A buzzing every few hours with no fill — The valve is being asked and is not answering.
- The bin is empty and the mould is full — Ice made and never released is a harvest problem, not a water one.
- Nothing has arrived for days and everything else works — Water and temperature are the two things to prove before anything else.
- A K unit of a different size behaves identically — That is what a shared build looks like: the members of this ladder differ in scale rather than in arrangement.
- NEAR MISS — the whole cabinet is warm — Fix the cooling first; ice is the last thing a struggling unit gives up.
Causes, most likely first on the K family
- Water not reaching the ice maker — It leads here. The mould never fills, so there is nothing to freeze and nothing to harvest.
- An ice maker module that no longer cycles — It sits behind the lead here. It is the cause that remains once water and temperature are both proved good.
- A water filter past its service point — It is third on this family. It is worth ruling out early because it costs nothing but a look at the date.
- A sealed-system fault behind the freezer section — Last on this family. When water, temperature and the module are all proved good, what remains is behind a panel and behind a licence.
- Body: This family keeps the brand-generic lead, but the order behind it is not the brand's. An ice maker module that no longer cycles has moved up into second place, ahead of a freezer section sitting above its ice-making temperature, and what moved it is the shape of this family's numbering rather than anything about the brand as a whole.
Check in this order, and why
- Check whether the valve was touched at the last move or service — A closed valve accounts for a large share of these and costs nothing to rule out.
- Once water and temperature are both proved, watch for a harvest attempt — What remains after those two is the module, and it is diagnosed by elimination.
- Compare cube size now with cube size a month ago — Gradual decline points at flow, and flow points at the filter.
- Establish whether the section has ever reached its ice-making temperature since the fault began — A section that never gets there points behind the panel and behind a licence.
- Body: Confirm which of the two K models you have first. The order below holds for both, but the access differs enough that guessing costs time.
Before you open anything
Safety
Power off first, every time. Unplug the appliance or switch off its breaker before removing a panel, since a capacitor can hold a charge after the power is off. Fan blades stay sharp and stay able to turn after the power is cut. Keep the interlock intact and let the fan stop on its own before reaching past it. Refrigerant work is licensed work: nothing on the sealed side of this machine is owner work, whatever the symptom looks like from the front.

When to call a technician
The line here is drawn at the first check that cannot be made from outside the cabinet. Work down the checks above first; they cost minutes and they remove most of this list. Call once they have all come back clean, because what is left is a sealed-system fault behind the freezer section, and that is the only item on this page that cannot be judged from outside the cabinet. Call straight away, without working down the list, if you smell burning or see oil outside the tubing at the back: oil outside the tubing means the system is open, and every hour it runs after that costs more to put right.
