Water separated from laundry by drying
is collected in the condensed water
container.
Empty the container after every
drying program.
TheContainerindicator light comes on
when the maximum water level in the
container has been reached.
It will go out when the door has been
opened and closed again.
Close the door completely.
Otherwise, the door and the
handgrip panel could be damaged
when the container is pulled out.

container.

Carry the container levelly so that
water does not pour out. Hold it by
the handgrip panel and the end.Empty the condensed water
container.

could cause health problems for
humans or pets.
You may use condensed water for
household uses (for steam ironing, or
for air humidifiers for instance). First
pass the condensed water through a
fine sieve or a coffee filter. The finest
lint, which might otherwise cause
damage, will be filtered from the water.
Cleaning and care
23 
						

							Cleaning the lint filtration
components
The lint filter in the door casing and lint
screens in the port-hole capture lint
generated by the drying process. Clean
them aftereverydrying*.
Cleaning without water
Tip: You can dispose of the lint without
touching it by using a vacuum cleaner.

Pull the door lint filter (1) out of the
door casing.

Rub or vacuum the lint from the
screen surface.Remove the lint from the space in the
door casing with a bottle brush or the
vacuum.
Wipe the door casing seal (2) all
around with a damp cloth.
Insert the cleaned door lint filter fully
into the door casing.
Wipe or vacuum the lint from both lint
screens in the port hole.

Close the door.
* Also check the lint screens and
door lint filter when theClean out
airwaysindicator light comes on.
Cleaning and care

							Cleaning with water
The lint screens and door lint filter
should be given a wet cleaningonly
when severely blocked or plugged.
Open the door and extract the door
lint filter from the door casing.
Remove both lint screens from the
port-hole:
Turn the left and right lint screen
knobs(until you hear them click).

Grasping the knobs, pull the lint
screens out towards the centre.

Clean all screens under running hot
water.

Shake the screens thoroughly until
drips are no longer visible.

Dry them thoroughly and with care.

Also clean the air passages
underneath the screens, using a
vacuum cleaner, for example.
When inserted, all lint screens

containing solvents, or glass or
all-purpose cleaners. They can
damage plastic surfaces and other
parts.

Dry all parts with a soft cloth.
Cleaning and care

							Cleaning the condenser (heat
exchanger) unit
Detergent residue, hair and fine lint
from the laundry can get through the
lint screen and plug the condenser.
Dust from the room taken in with the
cooling air can also cause blockages.
Checkthe condenser at least twice
a year and also if theFilter/Vent
indicator light comes on. For
frequent use, no later than
approximately every 100 drying
cycles. Clean it when necessary.
Removing the condenser unit

Remove the panel by pulling it
diagonally upwards and put it aside.Turn the locking lever on the inner
cover downwards.
Tilt the internal cover forwards.
Remove it by pulling it diagonally
upwards.

Rotate the locking lever on the
condenser upward (the locking lever
hook disengages from the groove in
the base).
Cleaning and care
26 
						

							Pull the condenser by its handleout
of its housing.
Checking the condenser unit
Hold the condenser up to the light in
two directions:

Look to see whether there is lint
inside it.
The arrows in the illustration above
indicate where to look.If no lint is visible:
Replace the condenser unit (see the
next page).
If lint is visible:
Clean the condenser unit as
described below.
Cleaning the condenser unit
When rinsing the condenser unit,
be sure to position it as shown in
the following two illustrations:

Rinse the unit from the longitudinal
side with a stream of water – as
shown in the top illustration.
Cleaning and care
27 
						

							Rinse the unit from the front with a
stream of water.
Check the condenser unit once more
for visible fouling (see "Checking the
Condenser Unit"). Rinse as often as
necessary.
Ensure that the condenser unit
rubber seals are clean.
Seals should not be removed and
must be free of kinks.
Checking and cleaning the condenser
unit housing

Check the condenser unit housing
inside the dryer for visible lint.
Using a damp cloth, wipe it only from
areas you can reach with your hand.Replacing the condenser unit
Push the condenser unit fully
(to the
stop) back into its housing.
The handle
of the unit must be on
top, the locking lever down.
Rotate the locking lever into the
horizontal position so that its hooks
clearly latch down into the groove in
the base of the housing.
When replacing the inner cover,
ensure that the rubber seal is
correctly seated in its groove.
Locate the inner cover so that its
latching hooks are down. While doing
so, hold it at an angle and push it
gently downwards.
Push against the cover and latch it
with its locking lever.
After latching, the locking lever must
be horizontal.
Insert the bottom of the external
panel and press until the upper edge
latches into position.
Only a correctly inserted and
latched condenser unit will ensure
the watertightness of the system!
