Troubleshooting  Section 5
Problem Possible Cause To Correct
Low ice capacity.
The condenser is dirty. Clean the condenser.
High air temperature around ice machine 
(air-cooled models).
Air temperature must not exceed 110°F 
(43°C).
Inadequate clearance around the ice 
machine.
Provide adequate clearance.
Objects stacked around ice machine, 
blocking airflow to condenser (air-cooled 
models)
Remove items blocking airflow.
Hot incoming water. Connect the ice machine to a cold water 
supply.
Incorrect incoming water pressure. 
Water pressure is too low or water filter is 
restricted.
Water pressure must be 20 – 80 psi (137.9 – 
551.5 kPa). Refer to section 2 for plumbing 
requirements. Replace water filter.
Safety Limit Feature
In addition to the standard safety controls, such as the high 
pressure cutout, your Manitowoc ice machine features built-
in safety limits, 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 On/Off button and turn off the ice machine, 
then press the On/Off button again to start the ice 
machine.
A.  If the safety limit 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 the previous page.
2.  Allow the ice machine to run to determine if the 
condition is recurring.
A.  If the ice machine stops again, the condition has 
recurred. Call for service.
B.  If the ice machine continues to run, the condition 
has corrected itself. Allow the ice machine to 
continue running.
