Hello, new to the forum. I have a 2003 D1 Californian spa. It went unused for about 7 years due to a bad circulation pump. Recently we decided to revive it. Cleaned up nice with a new cover, filters, topside control panel, ozone generator and ballast and a circulation pump with a built in flow switch. Everything works well except for a low flow message. The level is good, new filters, no air pockets. Really hate to call s tech if it’s something small. Any help or suggestions would be appreciated. Thank you in advance MSB
