FL1 code Sundance Caprio
Long time lurker first time poster. Bought a house with a hot tub in April. Hadn’t been used in a while, neighbors said probably 5 years as the prior owners never used the yard period. Was leaking from winter freeze damage; replaced some hoses and pvc where the flow switch mounts, new flow switch for good measure.
Filled it up today and turned on the power and it works! Jets are strong. Getting code FL 1 which says the flow switch is stuck in the open position.
Any thoughts on trouble shooting this? If I had the wires backwards on the flow switch, could that cause it?
