Plumbing
Connection to water supply
The machine should be connected to a
mains water supply in accordance with
standard regulations. The German auth-
orities do not require it to have a non-re-
turn valve as the washing machine has
been designed to comply with DVGW
regulations (German Association of
Gas and Water Engineers, see data
plate).
Connection to a mains water supply
should be carried out by a qualified
plumber and should incorporate a
mains stopcock with 3/4" thread
The 1.5 m long 3/8" pressure hose
should be connected to the stopcock
via the 3/4" threaded union.
This hose is not suitable for use for con-
nection to a hot water supply. Please
make sure that the washer sits correctly
in the union.

If connection is to be made to a stop-
cock with a short 3/4" thread, the extra
washers enclosed should also be in-
serted in the inlet hose union to com-
pensate.
The connection points are subject to
mains water pressure. Turn on the stop-
cock slowly and check for leaks. Cor-
rect the positioning of the washers and
screw unions if appropriate.
If replacing the inlet hose only use a
hose able to withstand pressure of up
to 70 bar. This also applies to all fittings
used. Miele original parts fulfil this con-
dition.
Longer hoses 2.5 or 4.0 m in length are
available as optional extras.
The pressure hose and solenoid inlet
valve are designed for a water flow-
pressures of between 1 and 10 bar
2
(981 kilonewtons/m
). At higher water
pressures it is essential to fit a reducer
valve.
There is a minimum flow pressure of 1
bar pressure if 5 litres of water flow into
a suitable container in 15 seconds.
The two dirt filters, one at the inlet
point, one in the pressure hose
union, must not be removed.
Caring for the environment
Caring for the environment means sav-
ing water, energy and detergent when
washing. This machine is equipped
with the Hydromatic System and the
Ball Valve for economical use of re-
sources. These systems offer a variety
of technical innovations e.g. the drum
ribs, which are designed to enable
economical washing without compromi-
sing on results.
The automatic load control facility en-
ables loads of between 1 and 5 kg to
be washed using only as much water
and electricity as is required for an ef-
fective wash.
Spinning at the high speed of
1200 rpm reduces drying times and en-
ergy consumption if laundry is dried in
a tumble dryer after washing.

Economy tips
To help you wash most economically,
remember the following tips:
Always wash with the maximum
laundry load specified for each pro-
gramme. This uses the energy to the
best advantage.
Only use the correct amount of deter-
gent required for the water hardness
level in your area, as recommended
by the manufacturer.
If laundry is not heavily stained, se-
lect a lower temperature setting than
indicated on the laundry care label
(but when using a lower temperature
do not select the "short"-option).
Lightly soiled laundry can be
washed using a "short"-programme
(additional temperature reduction
not recommended).
