damage
Preventing material damage
Follow these instructions to avoid ma-
terial damage and damage to the ap-
pliance.
ATTENTION!
The functionality of the appliance
may be impaired if you use the
wrong quantity of fabric softener, de-
tergent, care product or cleaning
agent.
▶Follow the dosage recommenda-
tions from the manufacturer.
Exceeding the maximum load capa-
city impairs the function of the appli-
ance.
▶Observe the maximum load capa-
city for each programme and do
not exceed it.
→"Programmes", Page25
The appliance is secured for trans-
portation using transit bolts. Transit
bolts which have not been removed
may result in material damage and
damage to the appliance.
▶Before starting up the appliance,
remove the transit bolts completely
and keep them in a safe place.
▶Before transport, fit the transit bolts
fully in order to prevent damage in
transit.
Material damage may be caused if
the water inlet hose is connected in-
correctly.
▶Tighten the screw connections on
the water inlet until they are hand-
tight.
▶Ideally, connect the water inlet
hose directly to the water tap,
without any additional connecting
elements such as adapters, exten-
sions, valves or similar.
▶Ensure that the inner diameter of
the water tap is at least 17 mm.
▶Make sure that the length of the
thread on the connection to the
water tap is at least 10 mm.
If the water pressure is too high or
too low, the appliance may not be
able to operate properly.
▶Ensure that the water pressure in
the water supply system is at least
100kPa (1bar) and max.
1000kPa (10bar).
▶If the water pressure exceeds the
maximum value specified, a pres-
sure-reducing valve must be in-
stalled between the drinking water
connection and the hose set of the
appliance.
▶Do not connect the appliance to
the mixer tap of an unpressurised
hot-water boiler.
Modified or damaged water hoses
may result in material damage and
damage to the appliance.
▶Never kink, crush, modify or cut
through water hoses.
▶Only use the water hoses supplied
with the appliance or genuine
spare hoses.
▶Never re-use water hoses that
have been used before.
Operating the appliance using water
that is dirty or too hot may cause ma-
terial damage.
▶Only operate the appliance with
cold mains water.
Unsuitable cleaning products may
damage the surfaces of the appli-
ance.
▶Do not use harsh or abrasive de-
tergents.
▶Do not use cleaning products with
a high alcohol content.
▶Do not use hard scouring pads or
cleaning sponges.
▶Clean the appliance with nothing
but water and a soft, damp cloth.

3.1 Disposing of packaging
The packaging materials are environ-
mentally compatible and can be re-
cycled.
▶Sort the individual components by
type and dispose of them separ-
ately.
3.2 Save energy and con-
serve resources
If you follow these instructions, your
appliance will use less electricity and
less water.
Choose programmes with low tem-
peratures and longer wash times and
use maximum load capacity
→Page25.
aEnergy consumption and water
consumption is most efficient.
Use the economy programme set-
tings.
aIf you adjust the programme set-
tings for a programme, the display
shows the expected consumption.
Add →Page37 detergent based on
the laundry's degree of soiling.
aFor light to normal soiling, a smal-
ler amount of detergent is suffi-
cient. Observe the dosage recom-
mendation from the detergent
manufacturer.
Reduce the washing temperature for
lightly and normally soiled laundry.
aAt low temperatures, the appliance
consumes less energy. For light to
normal soiling, lower temperatures
than indicated on the care label
are also sufficient.
Set the maximum spin speed if you
want to dry the laundry in a tumble
dryer afterwards.
aThe drier the laundry, the shorter
the programme duration when dry-
ing which, in turn, reduces energy
consumption. A higher spin speed
reduces the residual moisture in
the laundry and increases the
volume of the spin noise.
Wash the laundry without prewash.
aWashing with prewash increases
the programme duration and in-
creases energy and water con-
sumption.
The appliance has a continuous
automatic load adjustment function.
aDepending on the type of fabric
and load capacity, the continuous
automatic load adjustment func-
tion optimally adjusts the water
consumption and programme dur-
ation.
The appliance comes with an Aqua-
Sensor.
aDuring the rinse cycle, the Aqua-
Sensor checks the degree of tur-
bidity of the rinsing water, and ad-
justs the duration and number of
rinse cycles accordingly.
