Low chlorine production

If you are testing water from a return, and you are sure the unit is generating (some operate on a duty cycle, on 75% time, off 25% time) you should see significantly higher Cl coming out of the return.

Are you sure your salt level is at least 2800 ppm? Sometimes the SWG does not give the correct reading.

I have had a SWG for over 5 years with excellent results. My cell has a 2 year warranty and is prorated for an additional 3 years.
When there are no experts around to help-you keep looking for info. and you almost become an expert yourself.
The only problem in all the 5 years was not product related. The problems I had were caused by Nitrate(from fertilizer) windblown or otherwise, and Phosphate.
With Nitrates you drain and refill. With Phosphate you can get a product at most pool stores called Phosfree ( or a comparable name) and add according to directions--usually a couple of ounces for a few weeks. This neutralizes it.
HACH Co. has Nitrate test strips,cat. 27454-25 which will read as low as 1ppm. The 25 strip bottle is around a buck a strip---a small price to pay when stumbling around in the dark. This nitrate/phosphate problem is very seldom addressed when asking your peers for help.
Make a point in asking the mfg. of your SWG how badly these affect the operation of you cell.
Good luck---if this helps get back to me.
