    Porcia (Italy) and Olawa (Poland). 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 overcomes the values by which they are calibrated.

    3 SERIES 8 GENERAL CHARACTERISTICS The ENV060 electronic control system consists of two electronic boards. One integrates the power and control functions and the selector, the other the display function, where also the LCD display is connected. The PCB is mounted on a casing fitted to the control panel.

  • Page 7: Configuration Of Control Panel

    Configuration of control panel The washing programmes, the functions of the selector knob and the various pushbuttons vary according to the model, since these are determined by the configuration of the appliance. 3.3.1 Programme selector (S1) The selector features 21 positions and incorporates the ON/OFF switch. The various positions of the selector may be configured to perform different washing programmes (ex: water level, drum movement, no.

  • Page 11 “CHILD LOCK” This function is inserted inside the option menu. When it is activated, this function locks all controls and the door opening, after starting the programme, so as the children cannot change or cancel the programme. To activate this function, select pushing the option button (P3) the line with “CHILD LOCK”.
  • Page 12 EXECUTION OF WASHING PROGRAMME During the washing cycle, the display shows: the name of the selected programme, the temperature and the spin speed of the cycle, the cycle phase and under an animated bar that indicates the washing cycle carried out (dark par of the bar) and the part of the programme to be executed (light part).
  • Page 13 BLOCK/ CANCELLATION OF THE CYCLE When a cycle is executing, it can be stopped or cancelled by turning the programme selector to OFF. When the appliance is switched on again, the display shows: “Press Start to resume program or press OK to cancel”.
  • Page 14: Demo

    4 DEMO A special programme allows the demonstration of the operation of these appliances in shops, without the connection to the water system, in an interactive way with the user: ♦ The interactive way consists in selecting any programme, introducing some options and, after pushing the start button, the appliance will execute only some phases of the programme, skipping those that cannot be performed (water fill, drain, heating).
