An electric S&B house water heater does the same thing. I occasionally hear mine from the upstairs bathroom. The boiling is on the surface of the element, but the contents of the whole tank is not boiling. If it did.... and the poppet didn't pop-it, then there's be a big mess.
A house water heater is generally set to 115° or a bit higher to reduce scalding hazards. However, due to the small volume of an RV WH, the temp is around 160°. This is mixed down with cold water to workable temps, but there's always a risk of scalding. 117°+ will scald; this is one of the reasons natural hot springers carry thermometers - I've measured water coming out of the ground at 180°. It cannot be finger-tested...
