Warning and Safety Instructions
Please read the operating instruc-
tions before using this machine for
the first time. They contain import-
ant information about the safety, use
and maintenance of the machine.
This will avoid the risk of accidents
and damage to the machine.
Keep these operating instructions in
a safe place and ensure that new
users are familiar with the content.
Pass them on any future owner of
the machine.
Correct usage
Only use the washer-extractor to
wash items which are declared by
the manufacturer to be machine-wash-
able on the wash-care label.
Any other applications may be dan-
gerous. The manufacturer is not liable
for damage resulting from improper
use or operation.
Do not let small children play with
the machine and its controls or
operate it. Please supervise its use by
the elderly or infirm.
Technical safety
Before setting up the machine
check it for any externally visible
damage.
Do not install or use a damaged ma-
chine.
Before connecting the machine, en-
sure that the connection data on
the data plate (fusing, voltage and fre-
quency) matches the mains electricity
supply. If in any doubt, consult a quali-
fied electrician.
The electrical safety of this ma-
chine can only be guaranteed
when continuity is complete between
the machine and an effective earthing
system which complies with local and
national regulations. It is most import-
ant that this basic safety requirement is
regularly tested by a qualified electri-
cian.
The manufacturer can not be held re-
sponsible for the consequences of an
inadequate earthing system.
The machine is built in accordance
with current safety requirements.
Unauthorised repairs could result in un-
foreseen dangers for the user, for
which the manufacturer can not accept
responsibility. Repairs should only be
undertaken by a Miele approved engin-
eer.
The machine is only completely iso-
lated from the electricity supply
when:
– the plug is withdrawn, or:
– it is switched off at the mains, or
– the mains fuse is withdrawn.

Warning and Safety Instructions
The best materials are used in the
manufacture of this machine, and
every care is taken to check all parts.
However, with time, deterioration of
parts can occur, especially with such
components as hoses, giving rise to
leaks. This should be borne in mind if
operating the machine without supervi-
sion. Check the hose regularly for signs
of wear, and change in good time, to
avoid leaks and subsequent damage.
Faulty components must only be
exchanged for Miele original spare
parts. Only when these parts are fitted
can the safety standards of the ma-
chine be guaranteed.
Use
Do not install your washing ma-
chine in rooms where sub-zero
temperatures may occur. Frozen hoses
may burst under pressure. The relia-
bility of the electronic control system
may be impaired at temperatures
below freezing point.
In countries where there are areas
which may be subject to infesta-
tion by cockroaches or other vermin,
pay particular attention to keeping the
appliance and its surroundings in a
clean condition at all times. Any dam-
age which may be caused by cock-
roaches or other vermin will not be
covered by the appliance guarantee.
Before using the machine for the
first time, check that the transit fit-
ting at the rear of the machine has
been removed (see “Installation”). Dur-
ing spinning, a transit fitting which is
still in place may result in damage to
both the machine and adjacent furni-
ture or appliances.
Turn off the stopcock if the ma-
chine will be left for any length of
time (e.g. holiday), especially if there is
no floor drain (gully) in the immediate
vacinity.
Flooding danger.
If hooking the drain hose into a
wash basin, check that the water can
drain off quickly enough to prevent the
sink from overflowing.
Make sure the drain hose is secure, so
that the force of the water flowing out of
the hose does not dislodge it. Other-
wise this will result in flooding.
Take care to ensure that foreign ob-
jects (e.g. nails, needles, coins,
paper clips, etc.) do not find their way
into the machine with the washing (e.g.
in pockets). Foreign objects can dam-
age components of the machine, which
in turn, can result in damage to the
washing.

Warning and Safety Instructions
If the correct amount of detergent
is dispensed, the machine should
not need to be descaled. If however,
you do wish to descale the machine,
only use proprietary non-corrosive de-
scaling agents and strictly observe the
instructions. Consult the Miele Cus-
tomer Service Department.
Textiles which have been pre-
treated in detergents containing
solvents must be thoroughly rinsed in
clean water before being washed in the
machine.
Never use detergents containing
solvents in this machine, as this
may result in damage to component
parts and create toxic fumes. Such
detergents also pose a fire and explo-
sion hazard.
Dye removers may contain sulphur
compounds which may damage
washing machines. Only use dyes or
dye removers specified by the manu-
facturer as being suitable for use in a
washing machine. Always observe the
manufacturer’s instructions carefully.
If washing at very high tempera-
tures remember that the porthole
glass will be hot. Do not let children
touch it during a hot wash programme.
Always make sure the drum is sta-
tionary before reaching in to
remove washing. Reaching into a mov-
ing drum is extremely dangerous.
Accessories
Accessory parts may only be fitted
when expressly approved by
Miele. If other parts are used, guaran-
tee, performance and product liability
claims may be invalidated.
Disposal of your old machine:
Before discarding an old machine
unplug it. Render the plug useless.
Cut off the cable directly behind the ap-
pliance to prevent misuse.

Washing environmentally and economically
Washing environmentally
Caring for the environment means sav-
ing water, energy and detergent when
washing. This machine is equipped
with the Hydromatic System and Miele
“wash system” with ball valve. These
systems contain a variety of technical
features, such as the drum ribs, which
are designed to enable economical
washing without compromising on
results.
The automatic load control facility en-
ables loads of between 1 and 5 kg to
be washed using only as much water
and electricity as is required for an ef-
fective wash.
Spinning at the high speed of 1200
rpm reduces drying times and energy
consumption if laundry is dried in a
tumble dryer after washing.
Economy tips
To help you wash most economically,
remember the following tips:
Always wash with the maximum
laundry load specified for each pro-
gramme. This uses the energy to the
best advantage.
Only use the correct amount of deter-
gent required for the water hardness
level in your area, as recommended
by the manufacturer.
If laundry is not heavily soiled, select
a lower temperature setting than indi-
cated on the laundry care label.
Use the SHORT programme for
laundry that just needs freshening
up, or is only very lightly soiled.
10

Before using for the first time
Important: the appliance must be
properly installed and connected to
the water and electricity supply ac-
cording to local and national regula-
tions.
Check that the transit fitting at the
rear has been removed.
For further information read the instruc-
tions on pages 35-43.
Washing out the machine
Any residual lubricants and water from
testing still in the machine should be
flushed out as follows:
Do not load any laundry in the ma-
chine.
Add a little detergent to compart-
ment j.
Turn the programme selector switch
to the “A” Cottons 60°C programme.
Press the Start hbutton.
Water hardness reminder
The amount of detergent will depend
on various factors including water hard-
ness. Your local water authority can ad-
vise on water hardness in your area.
The dial in the detergent box can be
set as a water hardness reminder (1-4,
see Chart p.14). Use the spatula (sup-
plied for opening the drain filter panel).
11

Preparing the wash load
Empty all pockets.
Foreign objects (e.g. nails, coins,
paper clips etc.) can cause dam-
age to textiles and components in
the machine.
Sort the laundry
Most garments have a textile care label
in the collar or side seam. Sort the
laundry by care label symbols.
Only wash items in this machine which
are declared by the manufacturer as
being machine washable on the textile
care label.
Dark textiles often contain excess dye,
and should be washed separately sev-
eral times before being included in a
mixed load.
Delicate textiles should be washed sep-
arately in a delicates programme.
Only wash textiles made from wool or
wool mixtures if they are declared as
being suitable for machine washing on
the textile care label.
Pre-treating the washing
Badly soiled areas, e.g. collars and
cuffs, and water soluble stains, can be
pre-treated with bar soap, liquid deter-
gent or detergent mixed into a solution
or paste.
With particularly stubborn stains ask
your Dry Cleaner for advice.
Do not use detergents containing sol-
vents in this machine.
Loading the drum
Unfold laundry and load loosely in the
drum. To achieve best results it is advis-
able to make up mixed loads consist-
ing of both large and small items. This
improves the washing effect and helps
distribute the load evenly to keep the
machine stable and reduce the noise
level during spinning. Overloading re-
duces the wash result and causes
more creasing.
It is advisable to weigh the load first to
make best use of the machine’s capac-
ity. (See pp. 21-23 for max. suggested
loads).
With curtains: Remove lead weights
and strips or place in a laundry bag.
Woollens and knitted garments should
be turned inside out if the manufacturer
recommends it.
Close the drum door
Make sure that there is no obstruction
between the drum door and seal.

Adding detergent
All modern detergents produced for
automatic washing machines are suit-
able, including liquid, compact (con-
centrated) and special application
detergents. Use dispensing aids, e.g.
balls, if these are supplied with the
detergent. Woollens and knitware con-
taining wool mixtures should be
washed using a detergent specifically
designed for washing woollens.
Add the right amount of detergent as
recommended on the packaging.
The amount dispensed will depend on
the following:
– the quantity of laundry
– the water hardness level
– the level of soiling
It is important to dispense the
correct amount, because . . .
. . . too little detergent results in the
following:
– The laundry will not be properly
clean and will in time become grey
and hard to the touch.
– Greasy particles cling to the laundry.
– Lime deposits on the heater ele-
ments.
. . . too much detergent results in the
following:
– Excessive foam.
– Low level of agitation.
– Poor washing and rinsing results.
Water Softeners
A water softener can be used to cut
down on the use of detergents in water
hardness ranges 2 - 4. Dispense ac-
cording to the amount specified on the
packaging. First add detergent and
then the water softener. Use a quantity
of detergent as for soft water.
We recommend:
if you wash using several components
(e.g. special application detergents),
dispense the agents in the following
order into compartment iand / or j.
1. Detergent
2. Water softener
3. Stain salts
This way the agents are distributed bet-
ter.

give body to items e.g. shirts, table-
cloths and bed linen. Add starch formu-
lations to the fabric conditioner com-
partment following the same procedure
as for fabric conditioner.
