Venting the water drain
If the on-site drainage connection is
situated lower than the guide path for
the lower basket rollers in the open
door, the drainage system must be
vented. Otherwise, a siphoning effect
during a programme can cause the
appliance to empty itself of water.
 Open the dishwasher door fully.
 Remove the lower basket.
 Insert a screwdriver into the middle
opening of the vent valve in the left
wash cabinet wall .
 Press the screwdriver further into the
opening and push it through the
membrane  behind.
The vent opening for the water drain is
now open.
