NOTE: Customers should be informed not to store drinks, juices, etc. in the ice maker.
Another phenomena that may be encountered in the ice machine is slushing. Often after servicing a unit, when
the unit is powered up, there is the temptation to leave the bin door open to be able to observe that the ICE
MAKING cycle begins properly.
When warm air is allowed to enter the bin area during the beginning of an ICE MAKING cycle, the water flowing
over the evaporator plate may only freeze into a loose slush. This slush will melt off the plate back into the
reservoir pan where it may cause the water pump to stall (stop operating).
If the bin door is closed after the slushing is noted, the slush in the reservoir pan will rapidly melt and the ice
maker will once again begin to operate properly.
