EQUIPMENT FAILURE MANAGEMENT

The circuit board (62) is equipped with a program that monitors the operation of the ice machine.
When there is an anomaly in this function, it controls the main components (gear motor (60), micro
gear motor (57), gas solenoid valve (28) and water solenoid valve (63)), in order to resolve the
aforementioned anomaly or protect the equipment in general. Read carefully the items below
related to equipment failure and its probable causes.
