Sundance Spa – FL1 error code
My Sundance Certa 780 Series hot tub is showing an error of FL1. I went through the manual diagnostics and the error is still there. I contacted Aquatech and they suggested I clean the filter with the FilterBrite. In the first 4 years we basically used one filter and never got this error message. Last year we bought 2 new filters and we switch between them so they are basically hardly used. Both filters have been cleaned in a tub overnight with FilterBrite. We have turned the hot tub off and on numerous times and tried both filters with no luck. Can it be something other than the filter? In the manual it refers to a potential “air lock” – do I push water into filter our hot tub to try to correct (I haven’t dealt with this yet). Our 5 year warranty is up this month. Your assistance/suggestions is greatly appreciated.
