Hello, I installed Fleck 5600sxt Water Softener 64,000 Grain Capacity (Fine Mesh for Iron Removal) in June 2019 in my new home. It worked fine till November. After that it stopped working. During the brine draw cycle it is pumping water into brine tank instead of pumping brine solution in to resin tank. I checked drain line and it is clear. Please help me with problem. Thanks in advance!
