1. A safety system for a kitchen device having a vessel and a lid, the safety system comprising:
a processor;
a retaining arm being pivotable about a first axis between a first free position and a retaining position, the retaining arm being adapted to, in the retaining position, retain the lid against the vessel;
a first sensor adapted to communicate a retaining signal to the processor when the retaining arm is in the retaining position;
a second sensor adapted to communicate a function signal to the processor, the function signal indicating a function of the lid; and
a securing hook, the securing hook being pivotable about a second axis between a second free position and a securing position, wherein, in the securing position, the securing hook secures the retaining arm in a secured retaining position to prevent the retaining arm from moving out of the securing position, and
a third sensor adapted to communicate a securing signal when the securing hook is in the securing position,
wherein the processor is adapted to select an operating mode of the kitchen device in response to the retaining signal and the function signal and, the first axis is spaced apart from the second axis.
