up.
134
Cause and remedy
The time of day display is deactivated. When the
appliance is switched off the display is dark and the
sensors will not react.
 As soon as the oven has been switched on again
the time will reappear in the display and the 
sensor will react (see "Settings – Time of day –
Clock display").
The oven is not switched on at the mains.
 Make sure that the plug is correctly inserted in the
socket and that the socket switch has been flicked
to on, or that the appliance has been switched on
at the mains.
 Check whether the mains fuse has tripped. If it
has, contact a qualified electrician or Miele.
 If you need to open the door, for instance because
there is still food in the oven use the opener
supplied to lever the door open. To do so push the
opener at an angle into the gap between the
control panel and the door at the same height at
as the  sensor. You can also pull the door open
by grasping the sides of the door with both hands
and pulling carefully until it opens.
The pyrolytic cleaning programme has started.

Danger of burning! During pyrolytic cleaning
the oven door will remain locked until the
temperature inside the oven drops to below
280 °C.
Do not attempt to lever open the door with the
opener as described above!
 Wait until the oven has cooled down. The door will
unlock itself automatically as soon as the
temperature in the oven has dropped below
280 °C.
Demo mode has been activated.
The oven can be operated but does not heat up.
 Deactivate demo mode. See "Settings -
Showroom programme".
