Sub-Zero ice maker display What to do when CLEAN flashing shows on the ice maker ### Kind of code Mode, 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. ### Usually leads to No repair Lift the water shutters and pour in the amount of Sub-Zero ice maker cleaner or sanitizer the guide lists for that step. ### Shows up as Ice Maker Light Flashing An ice maker light flashing where it used to glow steadily: a blinking power or ice light, a flashing clean or descale symbol, an add-water light, or a status light on the ice maker itself. ### Make Sub-Zero Sub-Zero ice maker service, for ice makers in built-in units and those under the counter. ### Source Sub-Zero UC-15I undercounter ice maker Use & Care Guide (subzero-wolf.com PDF) Sub-Zero UC-15I undercounter ice makers. ## Before you book, in this order.

Lift the water shutters and pour in the amount of Sub-Zero ice maker cleaner or sanitizer the guide lists for that step. ### Why does CLEAN keep flashing on my Sub-Zero undercounter ice maker? The cycle is paused and waiting for cleaner or sanitizer. Once you pour it in, the cycle carries on through its rinses. ### What cleaner goes in a Sub-Zero UC-15I when CLEAN flashes? Sub-Zero says to use only the cleaner and sanitizer made for its ice maker. The guide also warns against vinegar and alcohol-based cleaners on interior surfaces. ### How often should a Sub-Zero UC-15I go through a cleaning cycle?
