If a Salt bridge has formed in your Aquamaster Water Softener due to high humidity, being overfilled or the wrong kind of salt is being used (crystal) it can easily be removed. 

Test with a blunt object like a broom handle. Push the handle into the salt to dislodge the salt bridge, or use hot water around the inside perimeter to loosen salt and then manually regenerate.  You may want to repeat this procedure a couple times a week until salt clog slowly disappears.  Check out this video on salt clog removal.
