Possible cause and solution
Protruding wash load items or other objects are preventing
the door from being closed properly by the Comfort lock.
Remove all objects and sort the wash load so that it

does not obstruct the door.
Close the door.

The float switch in the sump of the wash cabinet has not
been activated. The switch might be blocked.
Remove the filter combination.

Check the float switch to make sure it moves freely. The

float switch is located in the sump of the wash cabinet
behind the spray arm.
A program was interrupted due to the spray arm speed
dropping below the set value because:
- items are obstructing the machine or basket spray arms.
Arrange the load so that the spray arms can turn easily

and start the program again.
- wash pressure is too low due to a heavy build-up of foam.
Follow the instructions regarding foam build-up in

"Chemical processes and technology."
- Spilled rinse aid was not wiped away after filling or rinsed
away by the program
build-up during the next program sequence.
Start the Rinse program to clean the wash chamber.

After that, reprocess the load.

A program was canceled because there is not enough
spray pressure. The filters in the wash chamber may be
blocked.
 Danger of injury from glass shards, needles etc.
which are retained in the filter.
Check and clean the filters in the wash chamber (see

"Maintenance/Cleaning the filters in the wash chamber").
