Thanks for the link and page info! I dont see my exact top side but I could probably make one of those work. I woudl assume that since when the spa turns on (flip the breaker on), the pumps all kick on...so the relays on the board are probably fine...and it would be the button on the topside that are bad. I can sometimes hit them 4-10 times and the pumps will kick on.
As for the heater, i assume you are suggesting to just replace the heater element. Hmm...that could save me some money for sure depending on topside cost.
I am in Arizona USA.
I took a closer look at the heater, and its a I-204 4KW by Correct Tech.
I was looking at replacing the whole spa pack so I could have better scheduling, I can only run the spa during certain hours when energy is cheaper etc.
