The water protection system
The Miele water protection system pro-
tects all parts of the washing machine
from water damage.
The system consists of three main com-
ponents:
– the inlet hose
– the electronic unit and drainage and
overflow protection
– the drain hose

Inlet hose
– The casing on the inlet hose contains
two solenoid valves , which cut off
the water intake directly at the stop-
cock. These valves provide two-fold
protection. In the event that one of
the valves is faulty, the other valve
will cut off the water intake.
Blocking the water intake at the stop-
cock means that the inlet hose is only
under pressure whilst water is being
taken into the machine. For the re-
mainder of the time, pressure on the
inlet hose is negligible.
– Protection against the solenoid
valves bursting
The solenoid valves are pressure
tested to between 7,000kPa and
10,000kPa against bursting.
– The double-skinned inlet hose has
a pressure-resistant inner hose and a
protective sleeve. Any leaking water
is fed into the sump through this
protective sleeve. A float switch
closes the solenoid valves, prevent-
ing any more water flowing into the
machine and water in the suds con-
tainer is pumped away.
