Safety feature
The hob lock can be used to prevent
the cooking zones from being switched
on inadvertently, when used either with
the oven, or oven with built-in hob con-
trols. It does not apply to the warming
zone.
The operating instructions for the oven
with built-in hob controls or the control
unit describe how to set the hob lock.
