It is never possible to open both doors at the same time. The door on the soiled
side remains unlocked prior to starting and the door on the cleaned side will be
locked. Both doors are locked on pressing the starting button. On completion of
the program sequence, the door on the clean side will unlock but the other door
will remain locked. The cleaned dishware can then be removed whereafter the
