Troubleshooting

Service Limit Feature

This Maitowoc ice machine features built-in service 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 power button and turn off the ice machine, then press the power button again to start the ice machine.
A. If the service 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.

SERVICE LIMIT LED OPERATION

The service LED will flash when one of the five service limits are exceeded. When the service button is pressed the LED will
flash the corresponding number for the fault condition. For example if service limit 2 occurred, the service light will flash twice.
• Only the most recent service limit is saved to memory.
• Service limits are stored in memory for 100 cycles, then erased.

SERVICE LIMIT 1 LONG FREEZE CYCLE

The maximum freeze time is 30 minutes at which time the control board automatically initiates a harvest cycle.

SERVICE LIMIT 2 LONG HARVEST CYCLE

The maximum harvest time is 7 minutes at which time the control board either starts a prechill cycle or enters automatic
shutoff.

SERVICE LIMIT 3 WATER LOSS

In the Prechill cycle when the high and low water level float switches do not open within 4 minutes the ice machine stops.

SERVICE LIMIT 4 CONDENSATE PUMP FAULT

When the float switch on the condensate pump is open or the float switch jumper is disconnected from the wire harness the
ice machine stops.

SERVICE LIMIT 5 FULL BIN FAULT

When power is on and the ice machine has remained off for 24 hours the service LED will flash.
