FL1 error

We are getting an FL1 error after filling our hot tub. We have had the flo switch and circuit board replaced last spring because of this error. What is wrong?

    Wanda an FL1 msg after fresh filling the spa usually means there is an air lock. Releasing and air lock is done fairly easily by removing your filter and sticking your garden hose in the hole that your filter fits into. Wrap a rag around the hose so you have a tight fit. An FL1 msg can also be caused by a dirty filter or an obstruction in the circulation line or a bad connection at the flow switch or bad flow switch or plugged flow switch. A bad circulation pump can also cause an FL1 msg. If all else fails contact our Service Support Desk to book a diagnostic and repair of your spa.
