Connection to the water supply

The Waterproof system
Function
At the heart of this leak protection sys-
tem there is an electric safety valve,
which works like an automatic stop-
cock.
The Miele Waterproof system pro-
tects from water damage in the follow-
ing cases:
– Protection in the event of a leaking
machine.
Any leaking water is collected in a
sump in the base of the appliance. A
float switch switches off the safety
valve electrically, no more water will
flow into the machine. Water in the
suds container is pumped away.
– Protection in the event of a leaking
water inlet hose.
Leaking water is fed into the sump
through the protective covering
which surrounds the inlet hose as a
"second skin". The float switch swit-
ches off the water supply.

Fitting the Waterproof system
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).
The machine is designed to operate
with a minimum flow pressure of 1 bar.
There is a minimum flow pressure of 1
bar if 5 litres of water flow into a suit-
able container in 15 seconds.
The static water pressure must not ex-
ceed 10 bar. If it is higher than 10 bar it
is essential to fit a reducer valve.
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 connection point is subject to
mains water pressure. Turn on the
stopcock slowly and check for
leaks. Correct the position of the
washer and union if appropriate.
This appliance is not suitable for
connection to hot water.
