Troubleshooting
SafeGuard Feature
The ice machine will stop when conditions arise that
would cause major component failure.
Standby Mode
The first time a failure occurs, the ice machine de-
energizes and initiates a Standby Mode. The ice
machine will remain off for 60 minutes, then
automatically restart to see if the problem reoccurs.
During the Standby Mode the corresponding light
flashes continuously
(disch temp, water level or
speed)
. If the same failure keeps occurring, the ice
machine will initiate a SafeGuard Mode and remain off
until manually restarted.
SafeGuard Indicator Lights
During a SafeGuard Mode the corresponding light
(disch temp, water level or speed)
will flash
continuously.
The SafeGuard will remain in memory for 48 hours of
ice making time. After 48 hours of ice making time the
SafeGuard will automatically be erased. If power is
interrupted during the 48 hours, the timing will resume
when power is applied to the ice machine.
Placing the toggle switch in the OFF position:
The corresponding light will flash continuously.
Placing the toggle switch in the ICE position:
The light will de-energize and a start-up sequence will
initiate. The corresponding light will flash anytime the
toggle switch is placed in the OFF position provided
48 hours of ice making time has not been exceeded.
