70
Cause and remedy
To save energy, the drum lighting goes out automat-
ically after a set time and after the programme starts.
 Switch the dryer off and then on again.
 To switch the drum lighting on, open the door of
the tumble dryer.
The drum lighting is faulty.
The drum lighting is designed to last a long time and
should not normally need to be replaced.
 If you have tried everything but the drum lighting
still does not come on, contact the Miele Cus-
tomer Service Department.
When certain programmes are being used, water is
taken from the condensed water container and
sprayed into the drum. The spray jet can sometimes
stop working.
The fluff filter in the condensed water container is
clogged.
 Clean the fluff filter in the condensed water con-
tainer. See "Cleaning the fluff filter in the con-
densed water container" in this section.
There are heavy limescale deposits on the spray jet in
the door opening.
 Replace the spray jet. See "Replacing the con-
densed water spray jet" in this section.
 Only use condensed water. Do not use mains wa-
ter.
The frequent use of mains water leads to limescale
deposits.
