I have a year old Fleck 5600XT. A few days ago I noticed that it wasn’t softening the water and I discovered that the brine tank had a salt bridge. I broke it up and filled it with more salt. Now it is able to draw salt from the brine tank, but it isn’t actually softening the water. I’ve ran a regeneration cycle three times and it has gone through roughly 100lbs of salt without softening the water whatsoever. Any ideas on what the issue could be?
