I find it hard to believe that the circuit board and the heater crapped out simultaneously a few weeks back.l when refilling. That seems like it might be the case though. 🤦🏼.Right now though, everything seems to be working fine, but the heater. A Watkins rep suggested I try replacing the sensors first- so I ordered a new set of high limit and control sensors. I fear that maybe I broke something while I was fiddling with the heater a few weeks back BEFORE I realized I had a circuit board problem? (I took it apart, cracked the plastic slightly over tightening the high limit sensor). I am going to attempt the sensor swap out and if that doesn’t work- I am going to try a new heater. The relay board and main board are showing that everything power wise is correct- so I’m hoping I can get this heater issue solved. With the weather in the northeast, I am constantly worrying about freezing pipes. I even filled up the hot tub this time with warmer water and it was around 94…steadily dropping to 82 now- it’s been a long process, hoping I’m getting to a solution. So thank you for your suggestion TJR- this part actually helped bring my spa back to life. I finally have power to the spa. My water is around 50 degrees and the heater does not seem to be working. I’m not sure what the issue could be- I’m getting the solid red light on the circuit board, so I’m kind of confused as to why it’s not heating up. Could the water be too cold?? Do I need warmer water to get it going? Quote Link to comment Share on other sites More sharing options...
