Miele KM 402 Operating Instructions Manual page 20

Your fryer is fitted with a safety cut-out
which automatically switches it off if:
– the oil reservoir is not filled to at least
the lower level indicator.
– the fryer is switched on when empty.
– the fryer is switched on when the
heating element has been raised
(e.g. for cleaning).
The fryer has cut out automatically
when neither the temperature indicator
light nor the operating indicator light is
on and the oil is no longer being
heated.
