Question about Philips HD9396/90

yes absolutely, no plastic in contact with the water.
excellent electric kettle

Yes, completely made of steel on the inside. I've had the kettle for a long time. Absolutely recommendable. Doesn't get hot on the outside and you can't burn yourself. You just have to be careful with the lid, as with others. Setting the desired temperature is also very practical. I am very satisfied. If you don't need the adjustable temperature, there is also a normal version of the same kettle. It is 1 to 1 the same product. It just doesn't have the function and is therefore cheaper.
