I have an older Viking spa that the heater, which was working perfect, just quit. I am experienced with electrical, so I got out my toolbox and dvom and found an open heater element. Replaced the element and refilled the tub, still no heat. With the spa running in standard mode, no trouble codes, I tested at the element, no power. I checked the fuses, all good.
When I had removed the old element, I noticed it was broken at one of the terminals (thus the open circuit). Could it have shorted and damaged the control board, or is there a reset on it that I am missing?
