Temp sensor is new. Came with the hearter core assy. I switched just the Flo Sensor. then the Temp, then the entire assy. Same Flo message with all changes. Also the temp goes up when I have it running. Started at 43 and after a few 20 min runs on high it was up to 48.
Guess I'm going to bite the bullet and order the board assy.
Instead of ordering this from Spa Depot and possibly having to go through this same issue in a couple years I would like to buy a setup that will still be in production in a couple years. Is there any other companies that I can buy a setup from?
