I changed my Flow Switch ( 2003 Sweetwater Cayman ) yesterday. When I powered the spa back up, I am now receiving a FL1 code. Here are my concerns – 1) is it possible that I did not get a good connection on the circuit board with the flow switch wires? Would that cause my Circ Pump to stop operating? The Circ Pump Worked great before this repair, when powered back up the Circ Pump acted sporadically then shuddered and won’t start up. The Hut Tube was also low on water due to a leaking heater from the area of the black box at the base of the heater U-shape tube. The filter was 1/2 exposed an probably took in air. Would an airlock cause the conditions I described sans the leaking heater
