Venting the drainage system
If the dishwasher drain hose is con
-
nected to a floor drain or to a drain
pipe that is less than 8" (20 cm)
above the floor, the drain must be
vented. Otherwise the water inside the
dishwasher may siphon out during the
wash program.
To vent the drain:
^
Open the dishwasher door and
remove the lower basket.
^
Cut off the vent cap located at the
right rear of the triple filter system, as
illustrated.
Additional note
Since all Miele dishwashers are
equipped with an odor trap and non-
return valve, the drain hose can be
connected directly to the drain pipe as
illustrated.
If plumbing codes require an external
air gap on the discharge side of the
dishwasher, the following requirements
must be met:
–
No part of the drain hose should be
higher than 39" (1 m).
–
If installed horizontally, the drain
hose can be up to 12 ft (3.5 m) long.
If the drain hose is angled upwards
in any way, it cannot be longer than
5 ft (1.5 m).
– The drain connection should be
made as close as possible to the
dishwasher.
– The internal diameter (
7
/
8
" or 22 mm)
of the drain hose should not be
reduced at any point.
