Essential precautions for safe use

Dry your hands and the appliance: Before each use, check that your hands, the base and the body of the kettle are dry to prevent the risk of electrocution.

No cooking in the kettle: The kettle is designed only to heat water. Cooking food in it may damage it irreversibly.
