I turned breaker off drained, cleaned, refilled and turned back on my hot tub (as I've down a handful of times). This time nothing on display. Checked wiring for power and fuses all were good. Had spa company guy look and said everything looked good but I had a fried circuit board. Now the circuit board runs from 430-560 from my looking for this specific one. My question is what could have caused it and am I wasting money to put the new board in just to be something else? Vita joli 2016 model. Came with house I bought 1.5 years ago.
Any help is appreciated.
