Problem solving guide
Remedy
– When connected to a joint
ducting system each dryer
must be equipped with a
non-return valve.
– Check the non-return flap
regularly for damage, and
replace it if necessary.
– It will switch on again after
the door has been closed
and then opened.
– If the lamp needs to be
replaced, follow the
instructions in "Changing the
lamp" at the end of this
section.
