The Miele Waterproof System - Miele W 3923 WPS Operating Instructions Manual

The Miele Waterproof system

The Miele Waterproof system protects
the washing machine from water
damage.
The system consists of three main
components:
1) the inlet hose
2) the electronic unit and the washing
machine housing
3) the drain hose
1) Inlet hose
– The inlet hose is fitted with an
additional electrical safety valve
which works like an automatic
stopcock and is housed in the inlet
hose connection box.
– It is pressure tested to between
7,000 and 10,000 kPa.
– The inlet hose has a protective
sleeve.
Any leaking water from the inlet hose
is fed into the sump through this
protective sleeve. A float switches off
the safety valve, preventing any
more water from flowing into the
machine and water in the suds
container is pumped away.

Installation and connection
2) Electronic unit and washing
machine housing
– Sump
Any leaking water is collected in a
sump in the base of the machine. A
float switches off the safety valves,
preventing any more water from
flowing into the machine and water in
the suds container is pumped away.
– Overflow protection
This prevents the washing machine
taking in too much water. If the water
level exceeds a certain level, the
drain pump switches in and pumps
the excess water away.
3) Drain hose
The drain hose is protected by a
ventilation system which prevents the
washing machine from being
emptied completely.
