Operating the washing machine
Control panel
The control field includes a time display and various sensor controls for temperature, spin speed, and extra options. Indicator lights alert to faults, excess detergent, or hygiene information. CapDosing allows for fabric care products, additives, or detergent in capsules.
Starting a programme
Select a programme using the programme selector. Adjust temperature and spin speed as needed. Extras can be added. Detergent and fabric conditioner are added to the dispenser drawer or via CapDosing. Touch the flashing Start/Add laundry sensor control to begin. Laundry can be added during the cycle if the lock symbol is not illuminated.
End of programme
The door remains locked during the anti-crease phase. Turn the programme selector to the 'O' position to unlock the door.
Washing environmentally
Load the machine to its maximum capacity for efficiency. Use programmes with longer running times for better energy and water conservation. Modern detergents allow for lower temperature washing. Regular machine cleaning is recommended.
