power supply during operation, and

affected by the power failure before
switching the cooking zone(s) back on
again.

do not react at all, or the safety lock
indicator and cooking zone display

recalibration of the sensor switches".
If this does not solve the problem,
please call the Miele Service
department.

... the outer area of a cooking zone
that has just been switched on glows
faster and more intensely than the
inner area
That is not a fault: the cooking zone is

zones").
... an F appears in the display for the
rear cooking zones, an E appears in
the display for the front cooking
zones and numbers appear in the
timer display
Interrupt the power supply to the hob
for approx. 1 minute.
If the problem persists after
reconnecting the appliance to the
power supply, please contact the Miele
Service department.
