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 washing machines fitted with the ENV06 electronic control
system.
Previous platforms (electronic/mechanical) used a safety pressure switch which controlled the minimum water
level in the tub, beneath which the supply to the heating element was interrupted.
The current electronic appliances manufactured (ENV06 platform) us a heating element with thermal fuses
(inside its branches) as safety, which interrupt if the water level drops below the minimum level permitted.
The incorporated NTC sensor contacts have step of 2.5 mm.
Do not remove/switch the NTC sensors between heating elements
The manual deals with the following topics:
•
general
characteristics
•
control panel and washing programmes
•
technical and functional characteristics
•
access to the electronic control system
For detailed information concerning hydraulic circuits, structural characteristics of the appliances and
accessibility, please refer to the presentation Service Manual:
•
Publication no. 599 37 47-13 for HEC washing machines
•
Publication no. 599 70 40-15 for HEC RIM-ARCHED washer-dryers

2 WARNINGS
Any work on electrical appliances must only be carried out by qualified
technicians.
Unplug the appliance before accessing internal components.
Before placing the appliance on its side, always empty all the water using the
purpose-provided system beside the drain filter.
Never place the appliance on its right side (electronic control system side): some
of the water in the detergent dispenser could leak onto the electrical components
and cause these to burn.
When replacing the heating element, replace it with one with the same
characteristics in order not to compromise the safety of the appliance
Removing the NTC sensor from the heating element is strictly prohibited.
