Undercounter ice machines
Which Sub-Zero units make clear ice and which make crescents?
It depends on which machine is making it. A dedicated undercounter ice machine freezes water against a chilled surface and sheds a finished batch into a bin below, which is why it needs a drain. An ice maker inside a refrigerator or freezer fills a mould and ejects it. Denver Sub-Zero Repair Experts diagnoses them as two different appliances.
Pattern
What we usually find
- The wrong machine in mind. Someone expects bar-quality ice from the maker in a refrigerator column, and no repair will make a mould produce what a chilled surface produces.
- Minerals, not the mechanism. Cloudiness follows the water far more often than it follows the machine, and a mould-type maker will never give the glassy cube a clear-ice machine does.
- A dedicated machine harvesting badly. When a batch comes off the surface broken or half-formed, the fault is in the freeze and the harvest, not in the water that was poured in.
- A mould maker with a short fill. Hollow or undersized cubes belong to that kind of machine, and they point at the supply rather than at the freezer.
Most often first. Order comes from what the visits keep turning up, not from a count.
Two mechanisms, two lists of things that go wrong
The dedicated machine runs a long freeze and a short harvest, sanitises itself on a cycle of its own, and drains everything it does not turn into ice. Its faults are drainage, scale on the freezing surface, the pump that moves water around it and the harvest that lets go late.
The maker built into a cold compartment has none of that. It fills a mould, waits for the freezer to do the work, and pushes the cubes into a bucket. Its faults are the fill: a shut-off arm, an inlet valve, a filter, a fill tube that has iced over.
Before you call
Two minutes, before anyone comes out
- Look at a single cube: a curved, part-cloudy one came out of a mould.
- Check whether the unit has a drain running out of the back; a dedicated machine always does.
