The Miele “Waterproof system” con-
nected between the stopcock and the
machine offers the safest protection
against water leaks.
For the “Waterproof system” to function
correctly, it may only be fitted in the po-
sitions shown (see illustrations).
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.
The “Waterproof system” is NOT
suitable for connection to a hot
water supply.
The protective sleeve of the hose must
not be damaged (see illustration).
The “Waterproof system” with a hose
length of approx. 4.5 metres is avail-
able as an optional extra.
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”
protects from water damage in the fol-
lowing 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 the safety valve
off electrically, no more water will flow
in.
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 switches off the
water supply.
Maintenance
NB. If you intend to unscrew the “Water-
proof system” unit from the mains water
supply it is essential that the machine is
first disconnected from the electricity
supply.
Only use a genuine Miele “Waterproof
system” able to withstand pressure of
up to 70 bar, should you ever need a re-
placement.
In order to protect the water inlet
valves the two dirt filters, one in the
inlet union, the other in the solenoid
safety valve connection must not be
removed.
