Abstract

A method to safeguard an automated process in a household appliance, such as an assisted cooking process which has failure detection routines and failure handling routines. A number of failures and errors are discussed and a response to a detected failure is based on a control parameter such as an input power to the cooking process in order to trigger the magnitude of the response. A corresponding computer program product and kitchen hob with a sensor are provided as well.
