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
The Waterproof system (WPS)
a Two solenoid valves
b Double-skinned inlet hose
c Sump
d Float switch
e Electronic unit
f Drain pump
The inlet hoses
- The casing on the inlet hoses
contains two solenoid valves ,
which cut off the water intake directly
at the tap. 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 tap
means that the inlet hoses are only
under pressure whilst water is being
taken into the machine. For the
remainder of the time, pressure on
the inlet hoses is negligible.
- Protection against the solenoid
valves bursting.
The solenoid valves are pressure
tested to between 7000 kPa and
10000 kPa against bursting.
- The double-skinned inlet hoses
have 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,
preventing any more water flowing
into the machine and water in the
suds container is pumped away.
