Installation work, maintenance and
repairs may only be carried out by
suitably qualified and competent
persons in accordance with national
and local safety regulations.
Repairs and other work by
unqualified persons could be
dangerous and the manufacturer will
not be held liable.
Ensure current is not supplied to the
appliance until after maintenance or
repair work has been carried out.
Some minor problems can be corrected
without contacting the Miele Service
Department.
What to do if . . . .
. . . the display does not light up
^ Check whether
– the appliance is correctly plugged in
at the mains socket and switched on,
– the mains fuse has blown (call the
Service Department),
– the time display has been switched
off (see "Display" under "Settings").
. . . a programme will not start
^ Check whether
– the appliance door is properly shut if
operating in microwave mode,
– if operating in microwave mode a
power setting and time have been
entered,
– if operating with a combination
programme, the following have been
entered: a power setting, a time for
the microwave mode and a
temperature for the conventional
oven operating mode.
. . . no operating noise is heard when
the appliance door is opened during
a cooking process in conventional
oven mode
This is not a fault.
If the door is opened during a cooking
process the door contact switch will
switch off the heating and depending
on the function chosen, the hot air fan.
. . . a noise is heard after a process
has finished
This is not a fault.
The cooling fan continues to run for a
short time depending on how hot the
oven interior is.
If the door is opened during this run-on
time the fan will be switched off. If the
door is then shut the fan will start again.
. . . the microwave / heating functions
but not the interior lighting
^ Check whether the oven interior
lighting has been switched off, (see
"Light" in the "Settings" menu).
If it has not been switched off, the
halogen lamp is defective and needs to
be replaced:
Disconnect the appliance from the
electricity supply, (switch off and
unplug at the socket, or remove the
fuse, or switch off at the isolator as
appropriate).
