My kettle's thermostat only releases the power switch, but doesn't actually cut the power, so if something is blocking the switch from going to the "off"(up) position - like a large plate or something similar - it boils off all the water and then starts burning itself.
Happen once and I only noticed because the light was on and I couldn't hear the water boiling because it wasn't there anymore.
