The short answer for this family
An ice maker that has stopped producing on the Alpicool DT family points first at a kinked or blocked supply line. The order below is this family's own, and it is not the order the brand-generic article sets out. Of the causes listed here, all but one are owner-checkable, and an ice maker module that no longer cycles is the one worth ruling out immediately after the first.
What the owner sees
- 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.
- The freezer feels colder than usual but no ice arrives — Cold alone does not make ice; water has to get there.
- The arm sits higher than it used to — A bin packed to the top holds the arm where it reads full.
- A DT 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 — water on the floor rather than in the mould — A fill line letting go is the leak page.
Causes, most likely first on the DT family
- A kinked or blocked supply line — It is the first thing to rule out on these models. Small hollow cubes arrive first and no cubes arrive later, which dates the kink to the last time it was moved.
- An ice maker module that no longer cycles — It follows the lead on these models. It is diagnosed by elimination rather than by observation, which is why it sits where it does.
- A shut-off arm left in the off position — It comes after the two above it. Everything works and nothing is asked to run, which is the most frustrating outcome on the list.
- A sealed-system fault behind the freezer section — It ends the list. It is the least likely cause here and the only one with no owner-side check at all.
- Body: The brand-generic article on this symptom opens on water not reaching the ice maker. Here it does not: a kinked or blocked supply line has moved above it, and water not reaching the ice maker has moved down the list. 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 the line where it bends rather than where it connects — Crush damage is found by looking, and it is the cheapest thing here to put right.
- 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.
- Check whether anything tall in the bin is holding the arm up — A packed bin reads as full even when it is not.
- 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 DT models you have first. The order below holds for both, but the access differs enough that guessing costs time.
Before any panel comes off
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. Leave the door switch wired as it is: it cuts the fan when the door opens for a reason, and defeating it puts a hand near a blade that is still able to turn. The sealed system is out of scope for every check on this page. If a step would mean opening it, the step is a service call instead.

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 where the list stops being owner work. Two things end the owner-side list immediately: a burning smell, and oil anywhere outside the tubing. Both mean stop and call rather than continue.
