Instructions for use
INSTRUCTIONS FOR USE
1 Safety
The safety of AEG electrical appliances conforms to the recognised
technical regulations and the legislation covering the safety of appliances. However, as manufacturers, we still regard it as our responsibility
to inform you of the following safety information.
Before Putting into Operation for the First Time
• Refer to the ”Installation and Connection Instructions” later in this
user information.
• When the unit is delivered in winter months with minus temperatures: Store the washing machine for 24 hours at room temperature
before putting it into operation.
Correct Use
• The washing machine is only designed for normal domestic washing.
If the unit is used for purposes other than that for which it is
designed, the manufacturer can accept no liability for any resulting
damages.
• For safety reasons, conversions or modifications to the washing
machine are not permissible.
• Use only detergents which are suitable for washing machines. Follow
the washing detergent manufacturer's instructions.
• The washing must not contain any flammable solvents. Also remember this when washing pre-cleaned washing.
• Do not use the washing machine for chemical cleaning.
• Dyes/dye removers may only be used in washing machines if the
manufacturer expressly allows these products. We cannot be held liable for any resulting damage.
• Use only water from the water mains. Use rainwater or service water
only if it meets the requirements outlined in DIN1986 and DIN1988.
• Frost damage is not covered by the warranty! If the washing machine
is in a room which is at risk from frost, an emergency emptying operation must be carried out when there is a frost risk (see the section
”Carry Out Emergency Emptying”).
6
Instructions for use
Child Safety
• Packaging components (e.g. films, polystyrene) can be hazardous to
children. Risk of suffocation! Keep packaging away from children.
• Children often cannot recognise the hazards associated with handling
electrical appliances. Therefore, ensure the necessary supervision during operation and do not allow children to play with the washing
machine – there is a risk that children can get trapped inside.
• Ensure that children or small animals cannot climb into the washing
machine's drum.
• When disposing of the washing machine: Pull out the mains plug,
destroy the door lock, cut off the electrical supply lead and throw
away the plug and the left-over cable. This means that children at
play cannot shut themselves inside and in so doing be in danger.
General Safety
• Repairs to the washing machine may only be carried out by skilled
persons. Incorrect repairs can cause significant hazards. If repairs are
necessary, consult our Customer Service or your specialist dealer.
• Never put the washing machine into operation if the mains cable is
damaged or if the control panel, work top or base area are damaged
in such a way that the inside of the unit is open and accessible.
• Switch off the washing machine before carrying out cleaning, care
and maintenance work. Also pull the mains plug out of the socket or,
– if it is permanently connected, – switch off the LS switch in the
fuse box or completely unscrew the screw-in fuse.
• Never pull the cable to remove the plug from the socket. Always pull
the plug itself.
• Multiple connectors, couplings and extension cables must not be
used. There is a fire risk with overheating!
• Do not spray down the washing machine with a water jet. Electric
shock risk!
• The glass in the filling door becomes hot in the case of washing programs with high temperatures. Do not touch!
• Allow the washing solution to cool down before emergency emptying
of the unit, before cleaning or before emergency opening of the filling door.
• Small animals can chew the power cables and water hoses. Risk of
electric shock and danger of water damage! Keep small animals away
from the washing machine.

Instructions for use
2 Disposal
Dispose the packing material!
Dispose of your washing machine's packaging correctly. All packaging
materials are environmentally compatible and can be disposed of without risk or incinerated at a refuse combustion plant.
The plastics can also be reused:
• The outer sleeve and the bags are made of polyethylene (code >PE<).
• The cushioned parts are made of foamed, CFC-free polystyrene
(code >PS<).
The card parts were made from recylced paper and should also be
returned in the waste paper collection.
Dispose the old appliance!
When you finally put your appliance out of operation,
please bring it to your nearest recycling centre or to your dealer.
2 Environment Tips
• The pre-wash cycle is not required for averagely dirty washing. This
saves washing powder/liquid, water and time (and does not harm the
environment).
• The washing machine is especially economical when you fully utilise
the stated filling quantities.
• For small amounts of washing, use only half to two thirds the recommended amount of washing powder/liquid.
• Suitable pretreatment enables stains and small amounts of dirt to be
removed. You can then wash at a lower temperature.
• Use the energy-saving program to wash garments which are lightly to
moderately dirty.
• There is often no need for conditioner. Try it once! If you use a dryer,
your washing will become soft and velvety even without conditioner.
• In the case of medium to high water hardness, (hardness range II or
higher, see ”Washing and Care Agents”), you should use water softener.
The washing powder/liquid can then always be metered for hardness
range I (= soft).

Instructions for use
What Does ”Update” Mean?
The washing programs of your washing machine are controlled by software.
New types of textiles or new washing powders/liquids could, in the
future, require new washing programs. The software can be adapted to
these in most cases.
When new washing programs are available, you can also use them in
your washing machine by having the software updated.
For further information on the ”Update”, consult the Customer Service.
You can also ask the Customer Service about the costs of an ”Update”.
Water Protection Aqua Control
In the event of damage to the supply hose, the system blocks the further supply of water to the unit directly st the water tap.
If water escapes elsewhere, the drainage pump automatically pumps
off – even if the unit is switched off. The washing machine merely has
to be connected to the electricity mains.
14
Instructions for use
Before the First Wash
0 Carry out a washing operation without washing (COTTONS/WITTE WAS,
BLANC 95 °C, with half the quantity of washing powder/liquid).
This removes residues left over from production on the drum and solution container.
Prepare the Washing Cycle
Sort and Prepare the Washing
• Sort the washing according to care codes and type (see ”Washing
Types and Care Codes”).
• Empty pockets.
• Remove metal parts (paper clips, safety pins etc.).
• To prevent washing damage and washing snags: Close zip fasteners,
button closed bed covers and pillow cases, and tie together ribbons,
e.g. on aprons.
• Use clothing made of double-layer fabric (sleeping bag, anorak etc.).
• On knitted, coloured textiles and on wool and textiles with fitted
decorations: Turn inside out.
• Wash small and sensitive items (baby socks, stockings, tights, bras
etc.) in a washing net, a cushion with a zip fastener or in larger socks.
• Treat curtains with particular care. Remove small metal rollers or
small, burred rollers or tie them in a net or in a bag. We cannot
accept any liability for damage.
• Do not wash coloureds and whites together in one washing cycle.
Otherwise, whites will discolour or turn grey.
• New coloureds often contain surplus dye. It is best to wash such
items separately the first time.
• Mix small and large items of washing! This speeds up theeffect of
washing and the washing is more favourably distributed during spinning.
• Loosen up the washing before loading it into the washing machine.
• Put the washing into the drum folded out.
• Pay attention to the care instructions ”Wash separately” and ”Wash
separately several times”!
15
Instructions for use
Washing Types and Care Codes
The care codes help you choose the correct washing program. The
washing should be sorted according to type and care code. The temperatures stated in the care codes are all maximum values.
Cottons ç
Textiles made of cotton and linen with this care code are insensitive to
mechanical stress and high temperatures. The program COTTONS/LINEN
(WITTE/BONTE WAS, BLANC/COULEURS) is suitable for this type of
washing.
Linen èë
Textiles made of cotton and linen with this care code are insensitive to
mechanical stresses. The program COTTONS/LINEN (WITTE/BONTE WAS,
BLANC/COULEURS) is suitable for this type of washing.
Easy-Care Garments êí
Textiles such as finished cottons, cotton mixtures, viscose and synthetics with this care code require mechanically more mild treatment. The
program EASY-CARES/EASY IRON (KREUKHERSTELLEND, DEFROISSABLE/STRIJKVRIJ, SANS REPASSAGE) is suitable for this type of washing.
Delicates ì
Textiles such as layered fibres, microfibres, viscose, synthetics and curtains with this care code require very gentle treatment. The program
DELICATES (FIJNE WAS, LINGE DELICAT) is suitable for this type of
washing.
16
Wool and Very Sensitive Washing 9 ìï
Textiles such as wool, wool mixtures and silk with this care code are
especially sensitive to mechanical stresses. The program WOOLLENS
(WOL, LAINE)/P (handwash) is suitable for this type of textiles.
Attention! Textiles with the care codeñ (Do not wash!) must not be
washed in the washing machine!
Instructions for use
Washing Detergents and Care Agents
Which washing detergent and care agent?
Use only washing detergents and care agents which are suitable for use
in washing machines. Always follow the manufacturer's instructions.
How much washing detergent and care agent?
The amount to be used depends on:
• the dirtiness of the washing
• the hardness category of the mains water supply
• the filling quantity
If the detergent manufacturer gives no details of the dosing quantities
2
for minimum loads, add one third less for half loads and, in the case of
very small loads and for EASY IRON (STRIJKVRIJ, SANS REPASSAGE),
only half the amount of detergent recommended for a full load.
Refer to the detergent/care agent manufacturer's instructions on use
and dosage.
Water Softener
For medium to high water hardness (hardness category II or higher) you
should use water softener. Pay attention to the manufacturer's instructions. Always then meter detergent for hardness category I (= soft). The
responsible water works can provide information on the local water
hardness.
Since the water softener is added before the main washing detergent,
2
(water pre-softening), eighty percent of the softener quantity stated on
the package is sufficient.
