I have a 12 year old Culligan Estate 2 water softener. When I do a manual regeneration it seems to work fine. If I do that every day, I get soft water. It does not work automatically. I have not changed any settings. The clock is running and the linkages appear to be OK. I did notice that the lever that is supposed to start a regen does not move as far when tripped by the wheel from the clock as when tripped by hand. Can anyone help?
