Monitor Icemaker System and Display If Service is Needed
The microprocessor observes the power supplied to the icemaker water valve solenoid. If the solenoid is energized
for more than 15 seconds, power to the icemaker system is disabled for 24 hours and an error code is logged (EC
30). (See Figure 3-24) If this happens five consecutive times, ICE and SERVICE on the LCD will flash and the ICE
ON/OFF key will be disabled (See Figure 3-25).
NOTE:
To clear the ICE and SERVICE error indicators, and reactivate the ICE ON/OFF key, the problem must be
corrected, then the unit must be switched OFF and back ON, and the Alarm key must be pressed for 15 seconds to
clear the Error Code.
NOTE:
To allow ice to freeze fully and reduce effects of low water pressure, power to the icemaker system is inter-
rupted for 45 minutes after each ice harvest. This can be bypassed for service purposes by switching the icemaker
system OFF, then back ON by pressing the ICE ON/OFF key.
NOTE:
When in Sabbath Mode, icemaker system is disabled. Sabbath Mode will be covered later.
