I open mine up and clean grids after every 2 backwash and recharge cycles . not that hard . see what pressure reading you get on rinse cycle . you could have backpressure by a blockage or partially closed valve

After a backwash I let the pump run long enough to get a good circulation going and then I open it to bleed to air pressure off.
