Just moved in to a house this winter with a Jacuzzi Spa. I emptied it and cleaned it this spring. After refilling it I keep getting a flashing FLO error on the control panel and it does not heat up to the set temperature. The jets are working so I don’t think it is an air lock. I have cleaned the filters in a chemical solution and rinsed them off. Is there something I can do myself to fix this?
