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 proof to between 70
and 100 bar.
– 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.
2) Electronic unit and washing
machine housing
– Sump
Any leaking water is collected in a
sump in the base of the appliance. 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.
