Disposal of the packing mater-
ial
The packaging is designed to protect
the appliance from damage during
transportation. The packaging materials
used are selected from materials which
are environmentally friendly for disposal
and should be recycled.
Recycling the packaging reduces the
use of raw materials in the manufactur-
ing process and also reduces the
amount of waste in landfill sites.
Disposing of your old appli-
ance
Electronic and electrical appliances
contain many valuable materials. They
also contain certain materials, com-
pounds and components which were
essential for their correct functioning
and safety. These could be hazardous
to your health and to the environment if
disposed of with general waste or if
handled incorrectly. Please do not,
therefore, dispose of your old appliance
with general waste.
Take care not to damage your tumble
dryer’s pipework and heat exchanger
before or during transportation to an
authorised collection depot.
This is to ensure that coolant in the
tumble dryer and oil in the compressor
is contained, and will not leak into the
environment.
Please make use of officially designated
collection and disposal points to dis-
pose of and recycle electrical and elec-
tronic appliances in your local com-
munity, with your dealer or with Miele.
By law, you are solely responsible for
deleting any personal data from the ap-
pliance prior to disposal. Please ensure
that your old appliance poses no risk to
children while being stored prior to dis-
posal.

Correct application
 This tumble dryer is intended for use in domestic households and
similar working and residential environments.
 This tumble dryer is not intended for outdoor use.
 It must be used only as a domestic appliance to dry items which
have been washed in a water solution and which are marked on the
manufacturer's care label as being suitable for tumble drying. If us-
ing dry cleaning kits, do so at your own risk, and follow the instruc-
tions provided on the packaging.
Any other applications may be dangerous. Miele cannot be held li-
able for damage resulting from incorrect or improper use or opera-
tion.
 This tumble dryer can only be used by people with reduced phys-
ical, sensory or mental capabilities, or lack of experience or know-
ledge, if they are supervised whilst using it or have been shown how
to use it in a safe way and understand and recognise the con-
sequences of incorrect operation.
Safety with children
 Children under 8 years of age must be kept away from the tumble
dryer unless they are constantly supervised.
 Children 8 years and older may only use the tumble dryer unsu-
pervised if they have been shown how to use it safely and recognise
and understand the consequences of incorrect operation.
 Children must not be allowed to clean or maintain the tumble
dryer unsupervised.
 Please supervise children in the vicinity of the tumble dryer and do
not let them play with it.

Warnings and safety instructions
9
Technical safety
 Before setting up the tumble dryer, check it for any externally vis-
ible damage.
Do not install or use a damaged tumble dryer.
 Before connecting the tumble dryer, ensure that the connection
data on the data plate (fuse rating, voltage and frequency) match the
mains electricity supply. If in any doubt, consult a qualified electri-
cian.
 Reliable and safe operation of this tumble dryer can only be as-
sured if it has been connected to the mains electricity supply.
 The electrical safety of this tumble dryer can only be guaranteed
when correctly earthed. It is essential that this standard safety re-
quirement is met. If in any doubt, please have the household wiring
system tested by a qualified electrician. Miele cannot be held liable
for the consequences of an inadequate earthing system (e.g. electric
shock).
 Do not connect the appliance to the mains electricity supply by an
extension lead, multi-socket adapter or similar. These can overheat
and are a fire hazard.
 If the electrical connection cable is faulty it must only be replaced
by a Miele authorised service technician to protect the user from
danger.

Warnings and safety instructions
10
 Unauthorised repairs could result in unforeseen dangers for the
user, for which Miele cannot accept liability. Repairs should only be
undertaken by a Miele approved service technician, otherwise any
subsequent damage will not be covered by the warranty.
 Faulty components must only be replaced by genuine Miele ori-
ginal spare parts. The manufacturer can only guarantee the safety of
the appliance when Miele replacement parts are used.
 The tumble dryer must be isolated from the electricity supply in
the event of a fault and during cleaning and maintenance.
 This tumble dryer must not be used in a non-stationary location
(e.g. on a ship).
 Do not make any alterations to the tumble dryer, unless authorised
to do so by Miele.

Warnings and safety instructions
11
 This tumble dryer is supplied with a special lamp to cope with
particular conditions (e.g. temperature, moisture, chemical resist-
ance, abrasion resistance and vibration). This special lamp must only
be used for the purpose it is intended for. It is not suitable for room
lighting. Replacement lamps may only be fitted by a Miele authorised
person or the Miele Service Department.
 This tumble dryer uses a gaseous refrigerant which is condensed
by the compressor. Having been increased to a high temperature
level as as result of the condensing process, the refrigerant passes
through a closed refrigerant circuit. The heat generated is transferred
to the drying air as flows through the heat exchanger.
- The humming noises caused by the heat pump during the drying
process are normal. They do not impair the efficient functioning of
the tumble dryer.
- The refrigerant is environmentally friendly and causes no damage
to the ozone layer.
Damage to the tumble dryer by switching it on too soon.
This can damage the heat pump.
After setting up the tumble dryer, wait for at least one hour before
starting a drying programme.

Warnings and safety instructions
12
 The R290 refrigerant contained in this tumble dryer is flammable
and explosive. If the tumble dryer is damaged, proceed as follows:
- Avoid naked flames or anything which creates a spark.
- Disconnect the tumble dryer from the electrical supply.
- Air the room where the tumble dryer is located.
- Contact the Miele Customer Service Department.
Risk of fire and explosion due to damage to the tumble dryer.
The refrigerant is flammable and explosive if it leaks.
Take measures to protect the tumble dryer against damage. Do not
make any alterations to the tumble dryer.
 Follow the instructions in “Installation” and “Technical data”.
 The accessibility of the plug must always be ensured, in order to
disconnect the tumble dryer from the mains.
 Do not block the gap between the bottom of the tumble dryer and
the floor with plinth facings, deep pile carpet etc. This would hinder a
sufficient flow of air to the dryer.
 Make sure the dryer door can be opened without hindrance after
installation.
Correct use
 The maximum load for this tumble dryer is 9.0 kg (dry weight).
The maximum recommended loads for individual programmes are
given in the Programme chart.
 To prevent the risk of fire, do not connect the tumble dryer via a
controllable socket (e.g. a timer or a peak-load switch-off device).
If the drying programme is interrupted before the end of the cooling
down phase, this could cause the laundry to self-ignite.

Warnings and safety instructions
13
 Warning: Do not switch the dryer off before the drying pro-
gramme has finished. If this is done, the laundry must be hung up or
spread out to cool it down.
 Fabric conditioner and similar products must be used according
to the instructions on the manufacturer's packaging.
 Remove all items from pockets (e.g. lighters, matches).
 The fluff filters must be cleaned after every drying cycle.
 The fluff filters or the plinth filter must be thoroughly dried after
cleaning. Wet fluff/plinth filters could cause operational faults while
drying.

Warnings and safety instructions
14
 To prevent the risk of fire, textiles that have not been cleaned thor-
oughly or are still soiled with deposits of any kind must not be dried
in this tumble dryer. This applies in particular to textiles that
- have not been washed.
- have not been thoroughly cleaned and are still soiled with grease,
oil or other deposits (such as cooking oils, cosmetics, lotions,
etc.). If items have not been thoroughly cleaned, there is a danger
that they might ignite when heated, even after they have been re-
moved from the tumble dryer at the end of the programme.
- have been treated with inflammable cleaning agents or which
contain residues of acetone, alcohol, benzene, petrol, kerosene,
stain remover, turpentine, wax and wax remover or other chemic-
als (e.g. mops and floor cloths).
- items that have been splashed with hair lacquer, hair spray, nail
varnish remover or similar substances.
When washing such heavily soiled items:
ensure that you use sufficient detergent and select a high temper-
ature. If in doubt, wash the items several times.

Warnings and safety instructions
15
 To prevent the risk of fire, these textiles must not be tumble dried:
- textiles that have been cleaned using chemicals (e.g. professional
dry-cleaning agents)
- textiles which contain a large proportion of rubber, foam rubber or
rubber-like materials. For example, products made from latex
foam rubber, shower caps, waterproof textiles, rubberised articles
and items of clothing and pillows with foam rubber filling.
- textiles containing padding or fillings which are damaged (e.g. pil-
lows, jackets). The filling could fall out and cause a risk of fire.
 The heat pump that is essential to the operation of this tumble
dryer generates a great deal of heat inside its casing. There must be
a reliable means of dissipating this heat. Otherwise loads could take
longer to dry or the tumble dryer might sustain damage in the long
term.
The following mandatory requirements must be met:
- permanent room ventilation from the beginning to the end of
every drying programme
- a gap between the floor and the bottom of the tumble dryer (this
must not be blocked or obstructed in any way)
 The tumble dryer must not be hosed down.
 Do not let anyone sit or lean on the door, as this can cause the
tumble dryer to tip up.
 In many programmes, the heating phase is followed by a cooling
down phase to ensure that the items are not too hot to handle when
you remove them (this also avoids the danger of the laundry self-ig-
niting). The programme is not finished until the cooling down phase
has been completed.
As soon as the programme has finished, remove all laundry from the
drum.

Warnings and safety instructions
16
 Always close the door after use. This way you will avoid the
danger of:
- Children climbing onto or into the dryer or hiding things in it.
- Pets or other small animals climbing into it.
 The tumble dryer must not be used without fluff filters or
- with damaged fluff filters, or
- with a damaged plinth filter.
This would cause an excessive build-up of fluff which in turn would
cause a fault.
 Do not install the tumble dryer in a room where there is a risk of
frost occurring. At temperatures around freezing point the tumble
dryer may not be able to operate properly. There is a risk of damage
if the condensed water is allowed to freeze in the pump and hoses.
 If the water is drained externally through the drain hose instead of
being collected in the condensed water container, make sure the
drain hose is securely attached if you hang it in a sink or basin to
avoid the hose slipping and the water causing damage.
 Condensed water is not drinking water.
It can cause health problems in both people and animals if con-
sumed.
 Always keep the area around the tumble dryer free of dust and
fluff.
Dust drawn into the tumble dryer can cause blockages in the heat
exchanger over time.

Warnings and safety instructions
17
Using a fragrance flacon (optional accessory)
 Only use genuine Miele original fragrance flacons.
 The fragrance flacon must be stored in its packaging so please
make sure you retain this.
 Caution. The fragrance can leak out of the flacon. Make sure that
you always keep the flacon, or the fluff filter with the flacon inserted
in it, in a horizontal position when carrying and do not tip or place
down on any surface.
 Use an absorbent cloth to wipe up any fragrance which has
leaked out of the flacon onto the floor, the dryer or any dryer com-
ponents (e.g. the fluff filter) immediately.
 If fragrance which has leaked out of a flacon: comes into contact
with the skin - wash the skin thoroughly with soap and water; comes
in contact with the eyes - rinse the eyes with clean water for at least
15minutes; is swallowed - rinse out the mouth thoroughly with
clean water. Seek medical advice in the case of contact with the
eyes or if fragrance has been swallowed.
 If fragrance which has leaked out of a flacon comes in contact
with clothing, change the clothing immediately. Wash the clothing or
any cloths used for mopping up fragrance thoroughly with plenty of
water and detergent.
 There is the risk of fire or damage to the tumble dryer if the follow-
ing instructions are not observed:
- Never refill a flacon with fragrance.
- Never use a faulty fragrance flacon.
 Dispose of an empty fragrance flacon with the household waste
and never use it for any other purpose.
 Please also observe the information supplied with the fragrance
flacon.

Accessories
 Only use genuine Miele original spare parts and accessories with
this appliance. If non-Miele parts are used, warranty, performance
and product liability claims will be invalidated.
 The tumble dryer can be combined with a Miele washing machine
in a washer-dryer stack. The appropriate “WTV” stacking kit (avail-
able to order) to match your tumble dryer and washing machine is
required.
 If you order a plinth for this tumble dryer (available from Miele as
an optional accessory - depending on country), make sure it is the
correct one.
 Miele will guarantee to supply functional spare parts for a min-
imum of 10years and up to 15years following the discontinuation of
your tumble dryer.
