7. At the end of the programme
The machine stops automatically. The mains on light goes out. If you have selected a programme which ends with the water of the last rinse left in the tub, drain the water before opening the door. Select programme (drain) or (spin). Wait two or three minutes before opening the door to give the electric locking mechanism time to release it. Remove the laundry. Turn the drum by hand to make sure it is completely empty, so as to avoid any forgotten items being damaged in a subsequent wash (e.g. shrinking) or their colour running into a load of whites. Release any buttons which have been pressed. Turn the water tap off and unplug the machine. Leave the door ajar to air the machine.
