Only 1 green indicator light will light up, it's calling for salt, just had the water tested and there is more than enough salt. Removed the front panel and there is a red flashing light on the back of the pcm board ???
Welcome to TFP! We're going to need to know a little more about your SWG and automation system. Can you update your signature with the make/model of all the equipment you have there? If you're not sure, post a pic or two.
Also, what salt level does the owners manual call for on the SWG and what was the salt level tested?
