Hello, our 2012 j-325 is getting FL1 code. when i increase the temp the heat light will come on for about 3 secs then click off. can feel hot water shooting into tub for those 3 secs. after troubleshooting simple stuff (ex: clean filters) i reached out for help. the 1st tech said it was flow switch and it was replaced but same issue, the next tech said that flow switch tested fine and suggested he replace the board (to the tune of 525.00). i researched and decided to order new circuit board myself and replace, unfortunately we still have the same issue..frustrating!! the tub is fairly lightly used (not abused), water chemistry is always pretty good, etc. any suggestions you have to continue troubleshooting are appreciated. thanks..sf
