I have a 680 series Ramona with the FL1 error showing. I checked the manual and followed all directions to a “T” (page 44, 13.3) I am still getting the error code. The spa is only 4 months old and used less than a 2 dozen times. I purchased the spa at Country Comfort in Merced CA. I called and left a message for the owner this morning, but he won’t be in till Monday. Then, I saw your site so I figured I would see if I could do anything in the mean time.
