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 electronic
control system (SERIES 6).
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 (EWM10 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:
•
Settings: Demo, Diagnostics
•
Alarms
Consumption reduction mode
In order to reduce electricity waste when the cycle is not running, the appliance on this platform has two ways of
entering consumption reduction mode:
•
Stand-Off
Stand- Off – When the appliance is turned off using the ON/OFF button, it is in the “virtual” turn off “Stand-Off”
status; the LEDs and LCD screen are turned off and the buttons are disabled, but the main electronic
circuit board and some electric parts are powered electrically.
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.
Automatic turn off together with the Zero Watt circuit works in two ways:
1. 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).
2. 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.
3. If an alarm goes off when a wash programme is running, the automatic turn off is disabled showing the alarm.
