Safeguard Feature
In addition to standard safety controls, your Manitowoc ice machine features built-in SafeGuards. The ice machine will
stop when conditions arise that would cause major component failure.
RESET PROCEDURE
1. Move the ICE/OFF/CLEAN toggle switch to OFF
and then back to ICE.
A. If a safeguard feature has stopped the ice
machine, it will restart after a short delay.
Proceed to step 2.
B. If the ice machine does not restart, see “Ice
Machine Does Not Operate” on previous page.
2. Allow the ice machine to run to determine if the
condition is reoccurring.
A. If the ice machine continues to run, the condition
has corrected itself. Allow the ice machine to
continue running.
B. If the ice machine stops again, the condition has
reoccurred.

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 ICE position:
The light will de-energize and a start-up sequence will
initiate.
