Diagnostic Mode
Do not continue with the diagnosis of the ice maker if a fuse is blown, a circuit breaker is tripped, or if
there is less than a 120 volt power supply at the wall outlet. Units that failed during the first few days of
use should be checked for loose connections or miswiring.
Entering and Navigating — Manual Diagnostics
Turn the product to On. Within 10 seconds of Power On, press and hold the On and the Clean buttons.
Release both buttons when all user interface LEDs begin to flash.
Within 5 seconds of all LEDs flashing, push any other button (On, Off, or Clean). This begins manual
diagnostics. If no button is pressed within 5 seconds, the product goes into an automatic diagnostic
mode. Each component is cycled for 5 seconds.
The Off button is used to advance through each step. To exit manual diagnostics, press the On button .
After pressing any button to enter manual diagnostics all LEDs will illuminate for 5 seconds. The controls
will then automatically move to the first component.
