Notes on laundry
Labelling
of fabrics
Observe the following fabric symbols:
Do not tumble-dry the following fabrics:
 Impermeable fabrics (e.g. rubber-coated
fabrics).
 Delicate materials (silk, curtains made from
synthetic material) – they may crease
 Dripping-wet laundry – high energy
consumption
 Wool or fabrics containing wool.
 Observe the manufacturer's instructions.
DRYING
Drying in a tumble dryer permitted
Wring, hang on a washing line to dry
Do not wring, hang up wet and allow
to drip dry
Wring, lay on a flat surface to dry
Do not tumble dry

Tips on drying
Important for all drying cycles:
 To obtain a uniform drying result: sort the
laundry by fabric type and drying program.
 Fasten zips, hooks and eyes. Tie loose belts,
apron strings etc., together.
 Do not over-dry easy-care laundry: Risk of
creasing. Allow laundry to finish drying in the air.
 Do not over-dry laundry.
 Do not iron laundry immediately after drying.
Leave laundry folded up for a short while. This
helps the residual moisture to distribute evenly.
 Knitted fabrics (e.g. T-shirts, jerseys) often
shrink slightly the first time they are tumble-
dried. Do not use the Extra Dry programme.

15
Selecting a program
Selecting
Your dryer offers different programmes and the
additional Low Heat function for optimum drying
(see page 17).
Our drying programs are designed to protect your
laundry with minimum energy consumption. Your
laundry will feel damper than it really is because of
the residual warmth after drying.
If the degree of laundry drying still does not meet
your expectations after the laundry has cooled
down, please use the next-higher drying program
or the timer program.
Programme
sequence
During the Standard programmes, the dryer uses
an electronic sensor system which constantly
monitors how wet the laundry is. The drying
cycle automatically stops as soon as the level
of dryness set has been reached. The indicator
lamps (LEDs) display the programme status.

Cleaning and care
Cleaning
the dryer
!Risk of explosion
There is a risk of explosion from solvents.
Never use solvents for cleaning.
The dryer may be damaged if it is not cleaned
correctly. Do not spray the dryer with a water jet.
Do not use abrasive agents or general-purpose
cleaners.
 Clean the housing and the control panel with a
mild detergent and a soft cloth.
Fluff filter
Clean the fluff filter after each drying cycle.
Bobbling (fluff) occurs when fabrics become worn.
These bobbles come off during the drying cycle and
collect in the fluff filter.
A clogged filter results in longer drying times and
higher energy consumption.
1. Open the door.
2. Pull the filter out towards the top.
3. Remove the fluff (by drawing your hand across
the filter).
4. Replace the filter (it can only be inserted one
way round).
5. Close the door.
