Stops the appliance with water in the tub before the final rinse. Switches off the buzzer (if configured) To drain the water, select a drain or spin cycle.

  • Page 11: Sensitive

    4.5.10 Sensitive Adds one rinse in the COTTON – SYNTHETIC FABRICS cycles. During the cotton cycles the movements pass from vigorous to normal. Eliminates the intermediate spins except from the last two which are ar reduced speed. 4.5.11 Bleach Ducts water through the bleach compartment at the beginning of the first rinse in COTTON cycles. Pre-wash is possible only if there are three solenoids.

  • Page 12: Temperature Adjustment

    4.5.18 Temperature adjustment Used to select the washing temperature compatibly with the limit temperature for the cycle. Can be used during the cycle selection phase: the temperature can be modified only if the heating phase has not started (in pause mode) 4.5.19 Extra rinse Adds two rinses in the COTTON, SYNTHETICS and DELICATES cycles.

  • Page 13: Start/Reset" Button

    4.8 “START/RESET” Button This button performs two functions: • Cancels the programme: Press the button until the cycle LEDs switch off. The display will show three flashing hyphens. • Selects special programmes: In the programme selection and execution phases, this button can be used to cancel certain phases of the programme so that the appliance effectively performs a special cycle.

  • Page 14: Display (Some Models)

    4.9 Display (some models) The display shows the following information: Three flashing hyphens, when a programme is cancelled by pressing the SKIP/RESET button. The hyphens will also be displayed when the ON/OFF button is pressed to switch the appliance on, but only if the cycle selected previously has been cancelled.

  • Page 15: On/Off Button

    4.11 ON/OFF Button Press the ON/OFF button to switch the appliance ON. The display shows three flashing hyphens or a flashing zero. Press the same button to switch the appliance OFF. The ON/OFF button is an individual pushbutton, and is not part of the display board.
