I don't see a sensor button in the display for twindos; there is one for cap.

According to my research, this washing machine should be equipped with the TwinDos system and therefore have a corresponding sensor button. We are currently clarifying this with the responsible dealer. As soon as we have further information, we will announce it here.
Under "Setting programme sequence" the Twin System is programmed and after selecting a programme the display changes to the menu. See page 30 of the operating instructions
