The ice looks wrong
What are the white flakes in my drink?
The flecks are calcium out of your own water, not fragments of the machine. Sub-Zero names calcium deposits in water as the cause of white specks in cubes, showing themselves as ice shrinks and thaws. Denver Sub-Zero Repair Experts treats them as harmless unless they turn up beside a falling output.
Pattern
What we usually find
- Mineral in the supply, concentrated by the freeze. The water leaves first as a cube evaporates, and the solids stay behind as specks.
- A cartridge past its life, so more of that mineral reaches the mould than the design ever intended.
- Long storage in the bin. The longer a cube sits, the more it shrinks and the more obvious the residue becomes.
- Scale shedding from a mould that has been passing hard water for years, which is the version worth a visit.
Most often first. Order comes from what the visits keep turning up, not from a count.
Harmless, until it is not
Flecks are a cosmetic complaint on their own. The same minerals, though, are the ones that narrow an inlet screen, so a kitchen seeing specks this year often sees short cubes the next. Take them as an early reading rather than a defect.
What reduces them
A current Sub-Zero cartridge is the starting point. Where the supply is heavily mineral, Sub-Zero also suggests an in-line filter on the supply, which is a plumbing job rather than an appliance one. Nothing in the ice maker itself removes what is already dissolved.
Before you call
Two minutes, before anyone comes out
- Change the cartridge and see whether the next bin comes out cleaner.
- Rinse the bin out; loose residue collects in the bottom of it.
- Let a cube melt in a glass to confirm the specks are mineral.
Stop there. If that has not settled it by the next morning, call Denver Sub-Zero Repair Experts on (720) 903-2603 and the rest of the water path gets traced with a meter.
