Plumbing
Drainage
^ The drainage system is fitted with a
non-return valve which prevents dirty
water from flowing back into the
machine via the drain hose.
^ The machine should preferably be
connected to a separate drainage
system on-site.
If separate drainage is not available
contact your Miele application
specialist for professional advice.
The on-site drain connection point
should be sited between 0.3 m and 1
m above the lower edge of the
machine.
If it is lower than 0.3 m lay the hose in
a curve at a height of at least 0.3 m.
The drainage system must be able to
take a minimum drainage flow of 16
l/min.
^ The inlet hose is approx. 1.4 m long,
is flexible and has an internal
diameter of 22 mm. It must not be
shortened.
Hose clips are supplied for securing
it in position.
^ A longer drain hose (up to 4 m long)
is available to order from the Miele
Spare Parts Dept.
^ The drainage system must not
exceed 4 metres.
See also the installation diagram
supplied.
