I've got this problem with my Balboa spa. Here's the problem. They heating element will not turn off when the pumps turn off so the hot tub reads as overheat. You can actually hear the water boiling inside of the heating chamber. I have replaced the board, water flow pressure switch and temp sensor. Still having the same problem. Does anybody have any ideas?
