Emergency release

E.g. in the event of a power cut The programme continues when the power supply is restored. However, if the laundry has to be removed, the washing machine door can be opened as follows:

⇒Warning Risk of scalding!

When you are washing at high temperatures, there is a risk of scalding if you come into contact with hot water and laundry. If possible, leave it to cool down first.

⇒Warning Risk of injury!

You may injure your hands if you reach into the drum while it is turning. Do not reach into the drum when it is turning. Wait until the drum has stopped turning.

Any escaping water may cause water damage. Do not open the door if water can be seen through the glass.

1. Switch off the appliance. Pull out the mains plug.
2. Drain the water. ~ Page 27
