Miele KM 452 Operating Instructions Manual page 25

Each burner is equipped with a
temperature limiter. This limiter turns off
the heating elements in the burner
before the ceramic surface becomes
too hot. Once the ceramic surface has
cooled to a safe temperature, the
heating elements will automatically turn
back on.
The overheating protection can be
activated by:
– turning on a burner without putting a
pan on it.
– heating an empty pan.
– an uneven pan not sitting evenly on
the burner.
– the pan not conducting heat
properly.
If the heating elements cycle on and
off, even at the highest setting, the
overheating protection has been
activated.
