Can you put a plastic plate under the electric kettle to boil water?

Normal use is no problem, because the bottom is also plastic, but it is recommended to use stainless steel tray or wooden tray for safety. If there is spark in use, mainly consider contact oxidation and poor contact, and polish the contact to remove oxide. Of course, this kind of equipment also has a service life, usually it will be replaced in three to five years, and only by paying attention to maintenance can it be used for a longer time.
