Quoting from link to free manual shown:
FAILURE MODE
There are certain conditions that can be interpreted by the circuit board as a failure of the drive motor or motor
position switch. Upon failure detection the control will cease further operation. A telephone hand set symbol will be
shown in the upper left corner of the display and the error code will be shown. Listed below are the different error
codes.
1. Motor Always Turning
Error code "E1" occurs when the circuit board detects changes in the motor program switch when the motor is
not supposed to be turning. The phone icon and "E1" will be lit in the display.
2. Motor Never Turns
The Culligan Medallist Series control is equipped to detect no change in the motor position when the motor is
supposed to be turning (motor or piston locked in a frozen position). The AccuSoft circuit board will apply
power to the motor for 20 seconds. If there is no change in the motor homing or position switch, the control will
power down for 1 minute. The circuit board will repeat this procedure two more times in an attempt to remove the
obstruction. If no movement has been detected, the control will permanently power down and a phone icon and
an "E2" will appear in the display.
3. Homing Error
Error code "E3" occurs when the circuit board detects when the control is unexpectedly in the home position.
The phone icon and "E3" will be lit in the display.
Error Display Cancellation
The error code display can be removed by removing the power to the control for 1 minute. After clearing an error
condition, the control will default to the factory settings when power is restored.

SOURCE: Culligan medalist softener: Water continues to
Its a most common problem with culligan seal pacs. If your softener is under 5 years old you have the worst softener on the market. Culligan was bought out about 5 years ago by a canada group. they changed every thing and nothing is made in the usa any more. You will have to buy a new one from culligan and pay over 90.00 for it. The old seal pacs lasted 15 years or more now your lucky if you get 2 years.
SOURCE: No salt leaving Culligan softener during regen
It sounds like your salt in your salt compartment is stuck. Poor about a couple of gallons of hot water on top of your salt and see if that will break it up and fall down to the bottom of your salt container. Then regenerate your softener after about 3 hours have gone by. You should be back in business.
