  • Page 5: Purpose Of This Manual

    1 Purpose of this manual The purpose of this manual is to provide service engineers who are already familiar with the repair procedures for traditional washing machines with information regarding appliances fitted with the ENV06 electronic control system and produced in Porcia (Italy). The characteristic of the ENV06 electronic control system is to use only an electronic pressure switch to check the various water levels in the tub (with the elimination of the mechanical pressure switches: anti-overflow, anti- boiling, 1st-2nd level), and a new heater with two thermal fuses which interrupt if the temperature degree...
