Contacted Sears. They told me to go to sears.com and click on parts direct. Did not find any service information available there. Started up a "Sears" chat, where I was directed to managemylife.com. Did find some troubleshooting question and answer bits, but nothing specific to what I am looking for. Created an account and emailed them for service information whereabouts. They responded with KenmoreWater.com. This site has some great softener information for those that aren't too familiar with operation and maintenance, but nothing in major detail. Soooooooo, I'm still searching.
