The temperature sensor was too far out of the liquid. I ordered a Tc to female fitting that should fix it.Ya something is amiss. Keep in mind 5500W is a LOT of heat in a small cavity. It will heat it REALLY quickly. You must make sure:
1. Don't allow power to it unless you are sure there is adequate flow.
2. Don't allow too much power to it... if Duty Cycle, start really small. If PID put a cap on the max.
3. There is an exit for steam to escape... else bad things can happen!
