The water protection system

The Miele water protection system
protects all parts of the washing
machine 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
pressure of at least 7,000 kPa.
Electronic module and housing
- Floor tray: 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 floor tray 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.

Drain hose
The drain hose is protected by a
ventilation system which prevents the
washing machine from being emptied
completely.
