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 EWM09 SERIES 6 7
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 ( EWM09 platform) use a heating element with thermal fuses
(inside its branches) for safety, which interrupt in case of temperature overload caused by the water level
dropping below the minimum level permitted.
The incorporated NTC probe contacts have a 2.5 mm pitch.
The manual deals with the following topics:
•
General
characteristics
•
Control panel and compatibility between washing programmes and options
•
Settings: Demo, Diagnostics
•
Alarms
•
Technical and functional characteristics

Low consumption mode
In order to minimise electricity wastage when the cycle is not under way, appliances in this platform offer two
ways of enabling a low consumption mode:
1. Stand-off
When the appliance is switched off at the ON / OFF button, it is in the “Stand-Off” or “virtual” off status. The
LEDs and the LCD screen are turned off and the buttons are disabled, although the main circuit board and
certain electrical components are electrically powered.
There are two ways of disconnecting the electric power supply: the first is to remove the plug or integrate a
small electronic circuit known as Zero Watt (0 Watt) into the main electronic circuit board that automatically
turns off the appliance.
The auto off function combined with the Zero Watt (actual consumption
~
50 mW) works in two ways:
a.) When you press the ON / OFF button to turn off the appliance, the supply voltage is cut off and the washing
machine is secured (motor off, door locked, etc…), the cycle and any options selected are reset, so that the
next time the appliance is turned on, it is ready to perform the programme. (To open the door, you will have
to wait one or two minutes for the door safety lock to be released).
b.) If, after 5 minutes, during the selecting phase or after the end of the cycle, the appliance receives no further
instructions, it is automatically turned off (for energy savings in conformity with the standards on energy
consumption).
→
If this occurs during the setting stage, the programme and selected options are annulled and when
turned on again, the basic programme appears.
→
If the cycle has ended, all the settings are stored so that when the appliance is turned back on, the user
can see that the cycle ended normally, and can restart it if necessary.
If an alarm goes off when a wash programme is running, the automatic turn off is disabled showing the alarm.
