  • the gyro element 18 can be prevented from jamming in the cage 17 due to dirt particles. The dirt particles can be flushed through the gaps 29 . If the gyro element 18 is blocked, there is still very good emergency operation behavior.
  • the spray device 15 can also be attached below the wash items receptacles 12 to 14, for example to implement the intensive wash zone 16.
