Last night the display started displaying No Flow and the red and orange lights alternate flashing on and off. Flow meter reads 62 GPM (per the manual this unit requires a minimum of 40 GPM) and has worked in the past with flow as low as 35 GPM so definitely not a pump flow problem. Salt is at proper level. I shut off the power, removed cell and wires and reattached. Same thing. Cell is only 5 months old and has been working perfectly. Anyone have any ideas? Hoping there is some way of resetting the system other than shutting off power since I have already tried that. Otherwise guessing new cable assembly and if that does not work new board?
