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 qualified specialists. Incorrect repairs may result in significant risk to the user. If repairs are necessary, consult our customer service or your specialist dealer.

Never use the washing machine if the mains cable is damaged or the conrol panel, work surface or base panel area are so badly damaged that the interior of the unit is openly 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 circuit breaker at the household power distribution box or completely remove 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 risk of fire with overheating!

Do not spray down the washing machine with a water jet. Risk of electric shock!

The glass in the door becomes hot in the case of wash programmes with high temperatures. Do not touch!

Allow the washing solution to cool before carrying out an emergency emptying operation or cleaning the drain pump.

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.

7

Instructions for use

2 Disposal

Dispose the packing material!

Dispose of your washing machine's packaging correctly. All the packaging materials used are harmless to the environment and can be recycled.

• Plastic parts are marked with standard international abbreviations:

>PE<

for polyethylene, e.g. sheet wrapping material

>PS<

for polystyrene, e.g. padding material (always CFC-free)

>POM<

for polyoxymethylene, e.g. plastic clips

Cardboard packaging is manufactured from recycled paper and should be deposited in the waste paper collection for recycling.

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.

2Environment 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).

13

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.

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 at 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

0Carry out a washing operation without washing (COTTONS; KOCH-/ BUNTWÄSCHE, BLANC/COULEURS 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 (KOCH-/BUNTWÄSCHE, BLANC/COULEURS) is suitable for this type of washing.

Linen è ë

Textiles made of cotton and linen with this care code are insensitive to mechanical stresses. The program COTTONS/LINEN (KOCH-/BUNT- WÄSCHE, 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 (PFLEGELEICHT, TEXTILES MELANGES/ LEICHTBÜGELN, FACILE A REPASSER) 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 (FEINWÄSCHE, DELICAT) is suitable for this type of washing.

Wool and Very Sensitive Washing 9ì ï

Textiles such as wool, wool mixtures and silk with this care code are especially sensitive to mechanical stresses. The program WOOL (WOLLE, 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!

16

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

2 If the detergent manufacturer gives no details of the dosing quantities for minimum loads, add one third less for half loads and, in the case of very small loads and for EASY IRON (LEICHTBÜGELN, FACILE A REPASSER), 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.
