Yes, the reset button is under that clear plastic seal near the center of the black box with the green circle on it.
I use one of the door screws to push the reset. It takes a good solid push to do the job. The heater must be cool before it will reset - actually below about 90 degrees. If the water got that hot, then you will have to shut off power for a couple of hours to let the heater cool, then push the reset button.
