MAINTENANCE AND CLEANING
///////////////////////////WARNING/////////////////////////////
Disconnect electrical power before
beginning.
//////////////////////////////////////////////////////////////////////////
1. The bin control uses devices that sense
light, therefore they must be kept clean
enough so that they can "see". At least twice a
year, remove the bin control sensors from the
base of the ice chute, and wipe the inside
clean, as illustrated.
2. The ice machine senses water level by a
probe located in the water reservoir. At least
twice a year, the probe should be removed
from the reservoir, and the tip wiped clean of
mineral buildup.
