If the pretensioning device 19 is damaged, the engagement element 23 swivels due to its spring preload with the aid of the spring element 31 in the direction R1 counterclockwise towards the counter-engagement element 42 in order to come into positive engagement therewith.
  • the door 3 can be opened even if the pretensioning device 19 is damaged. In this way, even if the pretensioning device 19 is damaged, items to be washed can still be removed from the domestic dishwasher 1, for example.
  • the household dishwasher 1 can be easily assembled. The security is significantly increased since the door 3 is reliably intercepted in all of its positions. This reliably prevents injury to a user.
