What CLEAN flashing
actually means.
On the UC-15I, CLEAN glows green while the cleaning cycle runs and flashes when it is time to add the ice maker cleaner or sanitizer. The flash is a prompt inside the cycle, not a warning.

What to do when CLEAN flashing shows on the ice makerKind of codeMode, not a failure
Something the ice maker was switched into, often without anyone noticing, rather than something that broke: ice turned off from the panel or by the wire arm lifted while reaching into the bin, a control lock, a Sabbath setting, a cleaning cycle still running, a reminder that the water filter is due. No part has worn out, and the ice maker's own buttons or arm put it right.

Lift the water shutters and pour in the amount of Sub-Zero ice maker cleaner or sanitizer the guide lists for that step.

Before you book,
in this order.
Each step comes from Sub-Zero's own guidance for CLEAN flashing on its ice makers. Follow it to the end: the last card says whether this is a visit.
Lift the water shutters and pour in the amount of Sub-Zero ice maker cleaner or sanitizer the guide lists for that step.
Let the cycle finish its cleaning and rinse stages; the CLEAN light goes out when it is done.
If CLEAN flashes when no cleaning cycle was started, turn the unit off and on once and book a visit if it continues.
Cleared?
The ice maker is filling and dropping cubes again and no part was needed. If the same code returns during the next harvest, or water shows up on the floor again, book it as a new problem.
What not to do
A flashing CLEAN light is not a problem report. It only shows up because a cleaning or sanitizing cycle is in progress.

Door ice maker
The ice maker that feeds the dispenser on the outside of a door: tucked into an insulated box in the left door of a French door model, or at the top of the freezer side of a side-by-side, with a chute and an auger carrying cubes to your glass.
Freezer ice maker
The ice maker that sits inside the freezer compartment itself, a tray that twists or a mold with a heater and an ejector, dropping cubes into a bin or drawer you open by hand, with no dispenser on the door.
Undercounter ice maker
A built-in residential ice maker that lives under a kitchen, bar or basement counter, making clear cubes or chewable nugget ice on its own cooling system, with a water line in and a gravity drain or a small drain pump out.
In Sub-Zero's own words
“CLEAN” will illuminate green during the cleaning cycle and will flash to signal time to add cleaner and sanitizer.
