Cleaning and care

Deformations
Deformations indicate that the filter has
become blocked and worn by
continuous use.
Cracks, tears, indentations
Fluff will blow into the heat exchanger
unfiltered through cracks and tears and
will cause obstruction.
Deformations indicate that the filter has

White residues or residues of other
colours
Residues arise from laundry fibres and
residues of detergent components
which can clog the filter. They can be
found on the front and side edges of
the filter. In extreme cases, they can
form stubborn crusts.
Residues are a sign that the filter no
longer has a snug fit at the sides, even
if it appears to be perfect – fluff is
getting in unfiltered at the edges.
If these residues appear on the filter
again soon after cleaning, it must be
replaced.
