Problem solving guide

Installation, maintenance and repairs
may only be carried out by suitably
qualified and competent persons in
accordance with local and national
safety regulations.
Repairs and other work by
unqualified persons could be
dangerous, and the manufacturer
will not be held liable for
unauthorised work.
Some minor problems can be corrected
without contacting the Miele Service
Department.
What to do if . . .
. . . the oven does not heat up.
Check whether,
^ the function selector and the
temperature selector have been set
at the function and temperature
required.
^ the mains fuse has blown. If it has,
contact a qualified electrician or the
Miele Service Department.
. . . the heating works, but not the
oven lighting.
Make sure the halogen lamp is
connected properly in its socket.
If after checking it, it still does not work
you will need to change it:
^ Disconnect the appliance from the
electricity supply. Switch off at the
isolator or the mains fuse box.

^ Remove the runners.
^ Use the slide opener to lift the lamp
cover from its retainers.
^ Change the halogen lamp:
12 V, 20 W, heat resistant to 300°C,
Osram, Type w969.
Exercise caution when changing a
lamp. Halogen lamps get very hot
during use and will remain hot for some
time after being switched off.
Do not touch the surface directly
when changing the lamp as grease
particles from your fingers will
adhere to the surface and damage
it. Please follow the manufacturer's
instructions.
