Connection to water supply
The machine should be connected to a
mains water supply in accordance with
standard regulations. In Germany the
washing machine is not required to
have a non-return valve as it has been
designed to comply with the relevant
German DIN standard.
Connection to the mains water supply
should incorporate a mains stopcock
with 3/4’’ thread. The stopcock should
be fitted by a qualified plumber.
The approx. 1.5 m long 3/8" pressure
hose should be connected to the stop-
cock via the 3/4" threaded union.
This pressure hose is
not
suitable for
connection to a hot water supply.
Please make sure the washer sits cor-
rectly in the union.
The connection point is subject to
mains water pressure. Turn on the stop-
cock slowly and check for leaks.
If replacing the inlet hose only use a
hose able to withstand pressure of at
least 70 bar. This also applies to all
fixtures and fittings used. Miele orig-
inal parts fulfil this condition.
Longer hoses 2.5 or 4 metres in length
are available as optional extras.
The machine is designed to operate
with a water flow pressure of 1 bar mini-
mum up to 10 bar maximum. The static
water pressure must not exceed 10
bar. If it is higher than 10 bar it is essen-
tial 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 in the open
end of the inlet hose, one at the inlet
point in the solenoid valve must not be
removed.
