Question: If an electric kettle was used to pour water onto a non-kosher food item, does it need to be kashered?
Answer: This situation is potentially problematic because the hot water connects the non-kosher pot noodle to the urn.
However, if the pot noodle was cold (prior to this incident) then the only problematic area is the point of contact between the pot noodle and the hot water, and of this point of contact only a k’dei kelipah can pose a problem to the contents of the urn. Therefore, provided that the water in the urn contained sixty times the volume of the k’dei kelipah of this point of contact (or if there was more than one point of contact, sixty times all the points of contact), the issur becomes botel and the hot water inside of the urn, and the urn itself remain permitted.
