Does a plastic electric Shabbat kettle bought from a shop owned and run by Jews need to be Toveled? At the bottom, inside the kettle there is what appears to be a metallic plate, presumably what actually heats up the water.

The kettle itself needs to be Toveled with a Bracha, even though it's from plastic, since it has a heater that's metal (Sefer Hakashrut). Rabbi Ro'i Margalit
