The actual temperatures in the machine may deviate from these to achieve the optimum balance between energy saving and washing results. ■ Energy saving mode: The display panel light goes out after several minutes, and ▷ (Start/Reload) flashes. To reactivate the display, press any button. Energy saving mode is not activated while a programme is running. If you then dry the laundry in the appliance, select the maximum possible spin speed. The less water the laundry contains, the less time and energy are required for drying. Do not dry dripping wet laundry. ■ Ventilate the installation room well and clean the air inlet filter regularly. See Cleaning and maintenance, page 28, and Installation and connection, page 37.

Protecting your laundry and washer dryer:

Caution!

Damage to the appliance/textiles

Foreign objects (e.g. coins, paper clips, needles, nails) may damage the washing or components of the washer dryer.

The following instructions must be observed when preparing your laundry:

■ Always follow the manufacturer's instructions when dosing all detergents, cleaning aids, care products and cleaning agents. - Do not exceed maximum load. Overfilling will impair the washing result. - Keep detergents and agents for the pretreatment of laundry (e.g. stain remover, prewash sprays, etc.) away from the surfaces of the washer dryer. Using a damp cloth, immediately remove any fine spray residue and other residue or droplets.

■ Empty any pockets. Remove any foreign objects.

Illustration showing clothing items with arrows indicating direction of movement from a front pocket to other pieces, including accessories and accessories.

■ Remove metal parts (paper clips, etc.). ■ Trousers, knitwear and knitted textiles, e.g. jersey garments, T-shirts or sweatshirts, should be turned inside out. ■ Ensure that underwired bras are machine-washable. ■ Wash delicates in a net or bag (tights, underwired bras, etc.). ■ Close zips, button up covers. ■ Brush sand out of pockets and collars. ■ Remove curtain fittings or include in the net/bag.

Preparing laundry for drying

Note: To ensure an even drying result, sort the laundry according to the:

■ Type of fabric ■ Drying programme ■ Care symbols which are indicated on the care labels.

Only dry laundry which is labelled "dryer-proof" or which has the following care symbols:

■ ☐ = Dry at normal temperature (Intensive Dry ⚙)

■ ☑ = Dry at low temperature

(Gentle Dry ⚙️)

The following textiles must not be dried:

■ ☒ = care symbol "Do not dry" ■ Wool or textiles containing wool. ■ Delicates (silk, synthetic curtains). ■ Textiles which contain foam rubber or similar materials.

■ Textiles which were treated with flammable liquids, e.g. with stain remover, petroleum ether, thinners. Risk of explosion!

■ Textiles which still contain hairspray or similar substances.

Notes

■ Before drying, hand-washed textiles must be spun at the appropriate spin speed. ■ Before drying, spin at the optimum speed. A spin speed of more than 1000 rpm is recommended for cotton, more than 800 rpm for easy-care textiles. - Do not iron washing immediately after drying. It is recommended to roll the washing up first to distribute residual moisture evenly. ■ To ensure a good drying performance, quilts, terry cloths and other large textiles should be dried separately. Do not dry more than four terry cloths (or 3 kg). ■ Do not exceed maximum load.

The drying result is not satisfactory (laundry is not dry enough).Excessively high ambient temperature (above 30 °C) or inadequate ventilation in the room in which the washer dryer is situated. Ensure adequate ventilation to allow surplus heat to escape.The laundry has not been spun well enough before drying. Always set the highest selectable spin speed for the particular washing programme.Washer dryer overloaded: Observe the recommendations for the maximum load in the programme table and on the load display. Do not overload the washer dryer, as the maximum load for the drying phase is less than the maximum load for the wash cycle. Unload the washer dryer after washing with the maximum load and divide the laundry into two drying cycles.The power supply voltage is too low (below 200 V) – provide a suitable power supply.Air filter blocked?

For these types of textiles, select the timed drying programmes.
When the door is opened, you will notice that a small amount of water drips onto the dried laundry.The drying time is reduced for a smaller load. Some residual moisture may remain in the dryer system. If the door is opened quickly, a suction effect is generated which causes the moisture to drip out of the dryer system.Open the door slowly. Avoid wrenching the door open.

Connecting the water

BOSCH WVH28420SN - Connecting the water - 1

Warning

Risk of electric shock!

Danger of death if live parts come into contact with water.

Do not immerse the Aqua-Stop safety device in water (it contains an electric valve).

Caution!

Water damage

The connection points for the water supply and water drainage hoses are under high pressure. To prevent leakage or water damage, always follow the instructions in this chapter!

Notes

In addition to the safety information listed here, the local water and electricity supplier may have special requirements. ■ Operate the washer dryer with cold drinking water only. - Do not connect the washer dryer to the mixer tap of an unpressurised hot water boiler. ■ Use only the inlet hose supplied or one purchased from an authorised specialist outlet. Never use an used one! ■ If in doubt, have the appliance connected by a technician.

Water supply

Notes

  • Do not kink, crush, alter or cut through the water supply hose (otherwise, its strength can no longer be guaranteed). ■ Only tighten the screw connections by hand. If the screw connections are tightened too tightly using a tool (pliers), the threads may be damaged.

Optimum water pressure in the mains: 100–1000 kPa (1–10 bar)

■ When the tap is turned on, the water flow is at least 8 l/min. If the water pressure is higher, install a pressure reducing valve.

  1. Connect the water supply hose to the tap and to the appliance (except models with Aquastop):

Drainage into a wash basin

Warning

Risk of scalding!

When washing at high temperatures, you may be scalded if you touch the hot washing water (e.g. if draining hot washing water into a washbasin). Do not touch the hot washing water.

Caution!

Water damage

If the attached drainage hose slips out of the washbasin due to high water pressure when draining the appliance, leaking water may cause damage. Secure the drainage hose to prevent it from slipping out of the washbasin.

Caution!

Damage to appliance/textiles

If the end of the drainage hose is immersed in the drained water, water may be drawn back into the appliance and damage the washer dryer and/or textiles.

Ensure that:

■ the sealing plug does not block the outflow of the washbasin. ■ the water drains quickly enough. ■ the end of the drainage hose is not immersed in the drained water.
