Problem
Condensation is forming in
the drum.
94
Cause and remedy
You can remove the cover in the loading area to clean

the air guide area underneath.
The vent ducting or its openings are clogged with hair and
fluff, for example.
Check and clean all components in the vent ducting (e.g.

wall pipe, external grille, bends, elbows, etc.).
The flow of air is insufficient (e.g. because it is installed in a
small room).
When drying, open a door or window to ensure sufficient

ventilation.
The laundry has not been spun sufficiently.
Make sure that your laundry is thoroughly spun at the

appropriate spin speed in the washing machine.
The tumble dryer has been overloaded.
Do not exceed the maximum load size for the drying pro-

gramme selected.
Metallic components, e.g. zips, have prevented the tumble
dryer from registering the correct laundry moisture level.
Open any zips next time.

If the problem occurs again, dry garments with long zips

using the hot air drying programme.
The tumble dryer is installed on a shared exhaust air duct.
The tumble dryer must always be installed with a non-re-

turn flap when using a combined line.
Check the non-return flap for possible defects on a regu-

lar basis and replace the flap if necessary.
