pen the door and turn the ice maker

Pour four ounces of Sub-Zero ice maker
cleaner into the ice maker reservoir (see
side note).
4)

two hours.

the ice storage bin to melt the ice that has
formed. That ice will likely be white and
frosty looking.

and hot water, using that solution to scrub
the scale off of the liner.
8)
Rinse the liner with hot water.
9)
Sanitize the ice storage bin interior.

drain.
IMPORTANT NOTE: DO NOT
use automotive
antifreeze.
8)
Replace control box cover. Turn the ice
maker OFF and unplug the unit.

ICE MAKER ADJUSTMENTS
There are three items that may be adjusted:
cube size, storage bin ice level and harvest
time.
IMPORTANT NOTE:
Cube size and harvest
time adjustments should only be done by a
Sub-

CUBE SIZE ADJUSTMENT
The cube size control should only be adjusted
to bring the ice cubes to the correct shape; the
overall size cannot be adjusted. Try to adjust
the cube size control when the ice maker is in
the harvest cycle, or in the first ten minutes of
the freeze cycle.
