Hello! I am hoping to avoid a new spa pack. The issue is my 2014 bullfrog A7 throws a error code 19. It is a Bullfrog bfbp20 spa pack. Things I have tried.... snaked and cleaned every circulation pipe. Had the circulation pump test and no issues with it. I do have plenty of water flow currently. I replaced the sensors. I have tested the heater posts and checked for a heater short. I put the ipswich to test mode, and it is in the correct setup of setup 1. I have been told that I need a new board. Is this the correct solution, or is there any other way of resolving this? Thank you!!
