Connecting the water drainage sys-
tem
- The dishwasher drainage system has a
non-return valve, which prevents dirty wa-
ter from flowing back into the dishwasher
via the drain hose.
- The dishwasher drainage hose should be
connected to a separate on-site drainage
system for the dishwasher only. If no sep-
arate drain is available, we recommend
connecting it to a dual-chamber siphon.
The on-site connection must be between
12" (0.3 m) and 39" (1 m) in height, mea-
sured from the lower edge of the machine.
If the connection is lower than 12" (0.3 m),
the drain hose must be placed in an arc at
least 12" (0.3 m) high.
- The dishwasher is supplied with an ap-
prox. 59" (1.5 m) flexible drain hose with
an internal diameter of 7/8" (22 mm). Hose
clips are supplied with the dishwasher.
- The drain hose must not be shortened.
The hose can be extended using a con-
nection piece to attach a further length of
hose. The drainage length must not be
longer than 13 ft (4 m).
- The drainage system must be able to han-
dle a discharge rate of at least 4.2 gpm
(16 l/min).
 Damage caused by incorrect routing.
Make sure that there are no kinks in the
drain hose, and that it is not crushed or
stretched.
Make sure that there are no kinks in the
drain hose and that it is not crushed or

Please refer to the installation plan pro-
vided.
