The appliance contains refrigerant which, although it is environmentally friendly, is flammable R290. Failure to dispose of it properly may result in a fire or poisoning.

Dispose of the appliance properly and do not damage the pipes in the refrigerant circuit.

Energy-saving tips

■ Spin the laundry before drying. The drier the laundry, the shorter the drying time will be, thus consuming less energy.
- Load the dryer with the maximum load.
Note: Do not exceed the maximum load for the programs, as this prolongs the drying time and increases energy consumption.
- Ventilate the room and keep the air inlet on the dryer free to ensure air exchange.
■ Clean the fluff filter after each drying cycle. If the fluff filter is dirty, the drying time is prolonged and energy consumption is increased.
■ Energy saving mode: If the dryer is not operated for a prolonged period, it automatically switches off before the program starts and when the program has ended to save energy. The display panel and indicator lamps go off after a few minutes and the Start button flashes. To activate the lighting, press any button, open or close the dryer door or turn the program selector.

Draining the condensation water

Condensation will form in the appliance as it dries the laundry.

You must ensure that the drain hose is connected when you operate the appliance.

If there is no drain hose connected to the appliance, the condensation water from the appliance will run into the condensation container. In this case, you will need to empty the condensation container each time the dryer finishes drying the laundry, and also if it becomes full before drying is complete.

Connect the drain hose as follows:

  1. Remove the accessories from the dryer drum.

Warning

Risk of explosion/fire!

Remove any cigarette lighters and matches from pockets.

Caution!

The dryer drum and fabrics could be damaged.

Remove all objects from pockets and observe the following information:

■ Tie cloth belts, apron strings, etc. together or use a laundry bag.
- Close zips, hooks and eyelets and buttons. Button up large items of laundry, such as covers.
■ Remove any metal objects, such as paper clips, from pockets.
■ To ensure a consistent drying result, sort laundry by fabric type and drying programme.
■ Always dry very small items of laundry, e.g. babies' socks, together with large items such as towels.
- Knitted fabrics such as T-shirts and jerseys often shrink the first time they are tumble-dried. Use a gentle programme.
- Do not overdry easy-care laundry. This increases creasing of the laundry.
■ Use timed programmes for single garments.
■ Some detergents and care products, e.g. starch or softeners, contain particles which may be deposited on the moisture sensor. This may impair the sensor function and in consequence the drying result.

Notes

  • When washing laundry to be tumble-dried, use the correct amount of detergent and care products as specified in the manufacturer's instructions.
  • Clean the moisture sensor regularly → Page 30.

Sorting washing according to:

☐ Suitable for tumble drying
Dry at normal temperature
Dry at low temperature
Do not tumble-dry

Note: Do not load laundry from the washing machine directly into the tumble dryer. Sort the spun laundry before placing it in the dryer drum.

If you dry thin, thick and multi-layer fabrics together, they will dry to differing degrees. To achieve an even drying result, you should therefore only dry together laundry of the same type of fabric and structure. If you feel that the laundry is still too damp, you can select a timed programme for subsequent drying Page 21.

Caution!

Possibility of material damage to the dryer or laundry.

Do not tumble-dry the following fabrics:

■ Laundry contaminated with oil.
■ Unwashed fabrics.
■ Non-breathable fabrics (e.g. rubber-coated).
- Easily damaged fabrics such as silk, synthetic curtains.

Clean the fluff filter

Note: During drying, fluff and hair from the laundry is trapped by the fluff filter. If the fluff filter is blocked or dirty, this reduces the flow of air, which prevents the dryer from achieving its maximum performance. Clean fluff filters also reduce energy consumption and the drying time.

Clean the fluff filter after each drying cycle:

  1. Open the dryer door and remove all fluff from the door.
  2. Pull out the two-part fluff filter.

Caution!

The dryer may be damaged.

Do not operate the dryer without a fluff filter or if the fluff filter is defective.

Emptying the condensate container

By default, the condensation from the appliance runs into the condensation container.

Alternatively, you have the option of discharging the condensation water* supplied depending on the model. If you choose to discharge the condensation water into the waste-water system, you will not need to empty the condensation container during the drying programme or after each time you use the dryer.

  1. Pull out the condensate container horizontally.

Noises

Note: During drying, particularly in the initial phase, operation of the appliance results in noise from the compressor and pump. This is perfectly normal and does not impair proper functioning of the appliance.

From time to time, the compressor in the dryer generates a humming noise. However, the volume may vary depending on the programme and progress of the drying process.

Warning

Risk of death!

There is a risk of electric shock as the dryer is operated with electricity.

Disconnect the dryer from the mains before cleaning.

Clean the dryer using only water and a soft, damp cloth.

Remove all detergent residue, spray residue or other residues immediately. Do not use cleaning agents or agents for pre-treating laundry (e.g. prewash sprays, stain removers). Do not use high-pressure cleaners or steam jet cleaners to clean your appliance.

Cleaning the moisture sensor

Note: The dryer is equipped with a stainless-steel moisture sensor. The moisture sensor measures how damp the laundry is.

After long periods of usage the moisture sensor may become covered by a fine layer of limescale or residues of detergents and care products. Such residues must be removed regularly as the sensor function and in consequence the drying result may be impaired.

Open the door and clean the moisture sensor with a coarse sponge.

Faults and what to do about them

FaultsCause/remedy
on the display panel and drying has been interrupted.Empty the condensation container and press the Start button → Page 27.If the optional condensation drain* is installed, the drain hose may be blocked or kinked. Check the hose for deposits and rinse the hose. Lay the hose without any kinks.
on the display panel.Clean the fluff filter and press the Start button → Page 26.
selfCleaning on the display panel.Not a fault. The heat exchanger is cleaned automatically. Do not pull out the condensation container while this is displayed.
Dryer will not start.Mains plug plugged in or fuse checked?Programme selected? Select a programme.Dryer door open? Close the door.Is the childproof lock activated? Deactivate childproof lock."Ready in" time selected? Programme starts after a delay → Page 23.
Creasing.Creasing occurs when you have exceeded the maximum load or selected the wrong programme for the type of fabric. All the required information can be found in the programme table → Page 21.Remove clothes immediately after drying; creasing will occur if they are left in the drum.
Water is leaking out.Not a fault; the dryer may be sloping. Level the dryer.
Change in the programme duration displayed during drying.Not a fault. The moisture sensors detect the remaining moisture in the load and adjust the programme length (except timed programmes).
Laundry is not dried correctly or is still too damp.After the programme has ended, warm laundry feels damper than it actually is. Spread the laundry out and allow the heat to disperse.Finely adjust the dryness level - this extends the drying time but does not increase the temperature. Your laundry will become drier → Page 23.Select a programme with a longer drying time or increase the dryness level. This does not increase the temperature.Select a timed programme to add extra drying time for laundry that is still damp → Page 21.If you have exceeded the maximum load for the programme, the laundry may not be dried properly.Clean the moisture sensor in the drum. The sensor may become covered by a fine layer of limescale or residues of detergents and care products which then impair its function. Your laundry is not being dried correctly → Page 30.Drying has been interrupted as a result of a power cut, because the condensation container is full or because the maximum drying time has been exceeded.Note: See also the laundry tips → Page 20.

* Depending on the model

FaultsCause/remedy
Drying time too long?The fluff filter may be dirty and cause a longer drying time. Clean the fluff filter.If the air inlet on the dryer is blocked or not freely accessible, this may increase the drying time. Make sure that the air inlet remains unobstructed.The optimum ambient temperature for drying is between 15 °C and 30 °C. Outside of this range, the drying time may increase.Insufficient air circulation in the room may increase the drying time. Venti-late the room.
Display panel goes off and Start button flashes.Not a fault. Energy-saving mode is active → Page 12.
Residual water in the condensation container despite the dryer being connected to the con-densation drain*.Not a fault. If the condensation drain is installed, residual water remains in the condensation container due to the dryer's self-cleaning function.
Humidity in the room increases.Not a fault. Make sure the room is sufficiently ventilated.
Power cut.The drying programme is interrupted. Remove the laundry and spread it out or restart the programme.
Unusual noises when drying.Not a fault. Noises are produced by the automatic cleaning of the heat exchanger → Page 29.
The dryer feels cold despite drying.Not a fault. The dryer can dry efficiently at low temperatures using a heat pump.
