keilim - Tevila for a plastic kettle?


Does a kettle 1, whose body made of plastic, need tevila? (Do we consider the body, or the metallic resistor?)




1 A very classic electrical kettle, ie a jug with a warming resistor immersed into the liquid. There is an electric-connected base so that when the you put the kettle on the base, current flows through the resistor and water comes to ebullition. Afterwards you take the jug from the basis and you can bring it to the table.



Answer



Plastic doesn't require tevila but metal does (d'oraita according to many, see OU here under A). As such, if the metallic resistor touches the water (and I assume it does) then you need tevila with a blessing.


On utensils made of metal and plastic, kashrut.com (on top, letter b) writes




A utensil made of a material requiring tevilah should be immersed inclusive of any plastic or wooden parts attached to it. A utensil made of wood or plastic requires tevilah if any metal is attached to it, providing that the metal touches the food and is vital for the utensil’s use. A utensil made of separable parts requires tevilah only for its metal parts.



The OK writes



Electrical equipment that comes into direct contact with food requires tevila – for example, if one has an electric water urn, electric hot plate or popcorn maker, one needs to toivel at least the parts (if they come apart) of the equipment that touches the food. The wire does not need to be toiveled. (Some poskim hold that the wire should be toiveled.) It is preferable to wait a few days until the appliance is completely dry after it was toiveled before using. If one is concerned that it may get ruined, one should discuss this matter with a rov.



Kashrut.com here says the same for a pyrex kettle and practicalhalacha here for a tea kettle.


For more sources see Kof-K bottom of p. 5.


And as always (thanks Ezra for the reminder), don't trust what strangers write on the Internet and ask a rav for practical rulings.
