Drainage
The machine drainage system is
fitted with a non-return valve, which
prevents dirty water from flowing
back into the machine via the drain
hose.
The dishwasher is supplied with ap-
prox. 1.5 m of flexible drain hose
with an internal diameter of 22 mm.
The drain hose can be extended
using a connection piece and an
extra drain hose, (up to max. 4
metres).
If the hose is to be directly fitted to
the drainage outlet on site, use the
hose clip supplied.
The connection socket on the dish-
washer can be turned. The hose can
thus be laid to the right or left without
needing to loosen the hose clip.
The drain system must not exceed
4 metres. The drain pump has a
maximum delivery head of 1 metre.
The drain hose must not be short-
ened.
Venting the drainage system
Open the dishwasher door fully.
If the site drain connection is situated
lower than the guide path for the bot-
tom 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:
Cut off the top of the vent valve in
the wash cabinet.
