Hello Earl: The usual reason for the salt storage tank to be full of water is that the venturi for drawing the brine back into the resin is stopped up and it just continues to add brine water and not draw any back for regeneration.
There are instructions on the underside of the lip on the softener to clean the venturi.
Once you have that done you will need to remove the salt and water from the salt storage area and once you have the water out you can return the salt to the unit.
You will need to leave about 3 to 4 inches of water on the bottom for the brine will to use for the next regeneration after clean up.
I will provide you with a link to Kenmore water.com so you can look at the interactive sight for troubleshooting your water softener.
I hope this will help.
