Troubleshooting
Check the touchscreen for alerts - An alert icon with the
number of messages will be displayed if alerts are present.
Pressing the alert icon will display the alert log which will
allow viewing and resetting of alerts. Refer to the alert log
and event log on the following pages for a description of
the event.
NOTE: There are two sequences that allow the ice machine
to continue ice making during alert events:
Thaw Cycle
When the damper/curtain does not open during the 7
minute harvest cycle (E02 fault) a thaw cycle starts.
See ”Thaw Cycle” on page 88
Safe Operation Mode
Allows the ice machine to operate up to 72 hours if the
ice thickness probe (E19 fault) and/or water level probe
sensors fail (E20 fault).
See “Safe Operation Mode” on page 89
