The Water Protection System - Miele WMV 960 WPS Operating Instructions Manual

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

Installation and connection
Inlet hose
– The casing on the inlet hose contains
two solenoid valves , which cut off
the water intake directly at the
stopcock. 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
stopcock means that the inlet hose is
only under pressure whilst water is
being taken into the machine. For the
remainder of the time, pressure on
the inlet hose is negligible.
– Protection against the solenoid
valves bursting
The solenoid valves are pressure
tested to between 7,000 kPa and
10,000 kPa 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,
preventing any more water flowing
into the machine and water in the
suds container is pumped away.
