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.
