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 EWM10 electronic control system (SERIES 7/8). 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 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: Stand-Off 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 to cut off the electricity supply: the first involves unplugging the appliance at the socket or incorporating a small electronic circuit referred to as Zero Watt (0 Watt) into the main circuit board to turn the appliance off automatically. The auto off function combined 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 setting 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 phase, the programme and the options selected are cancelled and the basic programme appears when the appliance is turned back on. If the cycle has instead 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 occurs during a washing programme, the auto off function is disabled, and an alarm is displayed. A.D.L. 10 / 2010 4/26 599 73 54-08
