Got everthing hooked up on my rehab project. Spa controller is a Hercules 5000. I had replaced the air switch and everything was working well except no heat, which didn't surprise me because I figured I would have to replace the element. Now I only have the low speed function of the pump working and the air switch will not switch to the other functions. I was messing with the pressure switch , but would that cause my problem??? Might be looking at a new spa pack before I need rehab

My experience tells me that you would be better off getting a new pack. I contemplated getting parts replaced, but it just became too much hassle.
