The Miele water protection
system

The Miele water protection system

protects all parts of the washing
machine and surrounds from water
damage.
The system consists of three main
components:
- the inlet hose
- the electronic unit and drainage and
overflow protection
- the drain hose
Inlet hose
- Protection against bursting
The inlet hose is tested to withstand
pressures up to 7000 kPa.
Electronic unit and machine housing
- Sump: any leaking water from the
washing machine is collected in the
floor tray. There is a float switch to
close the water intake valve. The
water inlet is shut off and any water
inside the suds container is drained
away.
- Leak protection: any leaking water
that is not collected in the sump is
detected. The water inlet is shut off
and any water inside the suds
container is drained away.
- Overflow protection: this prevents the
washing machine from taking in too
much water and overflowing. If the
water level exceeds a certain level,
the drain pump switches on and
pumps the excess water away in a
controlled way.
Drain hose
The drain hose is protected by a
ventilation system which prevents the
washing machine from being emptied
completely.


Health risk and risk of damage
due to contaminated mains water.
The quality of the water used must
correspond to the drinking water
specification of the country in which
the washing machine is being
operated.
Always connect the washing
machine to potable water.
The water connection pressure needs
to be between 100 kPa (1 bar) and
1000 kPa (10 bar). If the water
connection pressure exceeds 1000 kPa,
a pressure reducing valve must be
installed.
A tap with a ¾ inch threaded union is
required for the connection. If this is not
available, only a qualified plumber may
connect the washing machine to the
mains water supply.
The screw thread is subject to water
connection pressure.
Check that the connection is
leakproof. Slowly turn on the tap.
Correct the position of the seal and
screw thread if necessary.
The washing machine is not suitable
for connection to a hot water supply.
