Does my tea kettle feature an auto-off option?

Model 6400
Model 6400 does not feature an auto-off option. It will continue to boil until the unit is unplugged. The auto-off feature is a feature that means there is a thermostat which will cut out if the tea kettle boils dry. The thermostat will continue to cycle on and off every few seconds until it is unplugged. To prevent damage to the teakettle, do not allow the product to boil dry.
