Why does my Pentair pool filter sound like a coffee percolator inside the tank after I shut the filter off?

Could be some debris caught on the sand that needs to be cleaned out, or indicating an air loc, or time for a sand change. Strange sounds should warrant some investigation into the cause to see if repairs need to be done.
