The display remains dark.
Problem
The efficiency of the tumble
dryer decreases.
Feather-filled pillows smell
after drying.
Items made of synthetic
fibres are charged with
static electricity after dry-
ing.
There is a build-up of fluff.
The drying process goes on
too long or even switches
off.
Cause and remedy
There is no power to the tumble dryer.
Check the mains plug, main switch and fuses (on site).
Cause and remedy
The fluff filter in the tumble dryer is dirty.
Check the fluff filter in the tumble dryer for contamination
and clean it if necessary.
Insufficient ventilation
Make sure that the air intake vent and the tumble dryer
ducting are not covered or blocked by objects.
Room temperature too high (>45 °C)
Ensure adequate ventilation of the installation site.
If necessary, connect the tumble dryer to external fresh air
and exhaust air ducting.
Feathers tend to develop a build-up of their own smell or
smells from other sources when they are heated.
Smells can be reduced through natural ventilation after
drying.
Synthetic fibres tend to attract static charge.
Static charge can be reduced by adding a fabric softener
to the final rinse in the washing programme.
Fluff is principally the result of friction when garments are
being worn and to some extent when they are being
washed. Machine drying hardly causes any fluff to form and
has no appreciable effect on the lifetime of the fabric.
Fluff is collected by the fluff filters and fine filter and can be
easily removed
(see "Cleaning and care").
In some circumstances, you may be asked to clean the air
channels/air guide.
Please check all the possible causes described below.
The fluff filter is clogged with fluff.
Remove the fluff.
The air guide area is clogged with hair and fluff, for example.
Clean the air guide area.
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.
