–
The machine's drainage system is
fitted with a non-return valve, which
prevents dirty water from flowing
back into the dishwasher via the
drain hose.
–
The machine should preferably be
connected to a separate drainage
system on site.
If separate drainage is not available
contact Miele for professional advice.
–
The dishwasher is supplied with
approx. 1.5 m of flexible drain hose
with an internal diameter of 22 mm.
Hose clips are supplied for securing
it in position.
– The drain hose can be extended
using a connection piece to attach a
further length of hose.
The drainage length must not be
longer than 4 m, and the delivery
head must not exceed 1 m.
– The drainage system must be able to
take a minimum drainage flow of
16 l/min.
–
The drain hose must not be
shortened.
,
Make sure that there are no
kinks in the hose, and that it is not
squashed or stretched.
Venting the drainage system
If the on-site drain connection is
situated lower than the guide path for
the bottom basket rollers in the open
door, the drainage system must be
vented. Otherwise a siphoning effect
during a programme can cause the
machine to empty itself of water.
To vent it:
^
Open the dishwasher door fully.
^
Pull the lower spray arm firmly
upwards to remove it.
^
Cut off the top of the vent valve in the
wash cabinet.
