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.

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.
