It's normal for new electronic appliances to have a modest smell either when on or in use, diswasher, oven, kettle is very normal. My fellow kettle also smelled for some time before it went away. Often these things are coated with some chemicals to prevent rust, other times these use a oil in the manufacturing process or it's insulation that smell when heated up. The chemical smells can take some cycles to get away, running cycles of water is standard procedure and is recommended by many manufacturers of different appliances even running them down with a damp microfibre cloth. Obviously chemicals isn't healthy so open your windows might be a good idea when in use until the worst evaporate. But obviously it should not be as bad that it smells hours after turned off or your whole house/apartment smell of it.
