Service Faults
In addition to the standard safety controls,
such as the high pressure cutout, your
Manitowoc ice machine features built-
in service faults which will stop the ice
machine if conditions arise which could
cause a major component failure.
Before calling for service, re-start the ice
machine using the following procedure:
1. Press the power button. The display
reads “Off”. Press the power button
again, and the display reads “Making
Ice”.
A. If a service fault 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 page 51.
2. Allow the ice machine to run to
determine if the condition repeats.
A. If the ice machine stops again, the
condition has repeated. Call for
service.
B. If the ice machine continues to
run, the condition has corrected
itself. Allow the ice machine to
continue running.
