... one or more residual heat
indicators are flashing
– There was an interruption to the
power supply during operation, and

... the sensor switches are over
sensitive or do not react at all
The sensitivity level of the sensor
switches has changed. It can be
corrected as follows:
– Make sure that there is no direct light
(from the sun or from an artificial
source) falling onto the hob and that
the surrounding area is not too dark.
– Make sure that there is nothing
covering the sensor switches or the
hob. Take any pans off the hob and
wipe away any food deposits.
– Interrupt the power supply to the hob
for approx. 1 minute.
Reconnect the hob to the electricity
supply. The electronic unit will reset the
sensitivity levels of the sensor switches.
If this does not solve the problem,
please call the Miele Service
department.
