Could be that the motor died, is not getting power, or something is bound. Could be that something jammed and the motor fried trying to drive it.
Fleck warranties their control valves for 5 years. If the softener is still under the 5 year warranty contact the selling dealer and they should assist you.
You can contact Fleck (Pentair) through this form...
click here and ask their advice.
If it is not under warranty then check the Yellow Pages under
water treatment for water treatment professionals. There's usually someone everywhere that services and repairs Fleck control valves.
You can try to do it yourself with the help of the service manuals. Parts are available on the internet but this forum's rules prohibit me posting a link.
Let us know how things work out.
