Have a aqua rite generator 3 yrs old. Suddenly not working. Have replaced the fuse, the tcell-15 When i turn back on it blinks no flow rapidly for 30 + seconds then goes blank. I checked the flow switch and it looks ok not obstructed. Last salt level sev wks ago was 3300. Live in midwest where it is very warm right now with pool temp 94! no cover on PH ok. Any ideas what to check next. I wonder if I need a new circuit/control board but not sure where to find one. The local pool dealers did not install this SWG and have no experience with aquarite but would be happy to install a intellchloinator for $2000+ Any suggestions would be appreciated.
