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 drain hose should be
permanently positioned, during
installation, so that its highest point is
located above the flood plane of the
sink that it is attached to.
– The on-site drain connection point
should be located between 1 ft.
(0.3 m) and 3' 3". (1 m) above the
lower edge of the machine.
If it is lower than 1 ft. (0.3 m), bend
the hose in a curve to a height of at
least 1 ft. (0.3 m).
The drainage system must be able to
take a minimum drainage flow of
4.5 gal/min (16 l/min).
– The flexible drain hose is 4' 7" (1.4 m)
long and has an internal diameter of
7
/ " (22 mm). Do not cut the drain

Hose clamps are supplied for
securing it into position.
– A longer drain hose (up to 13 ft.
[4 m] long) is available to from Miele.
