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 55.
