Lisa,
Well, logically, there is either not enough water flowing through the SWG or the flow switch is broken.
One thing that can cause the lack of flow through the SWCG is a dirty filter.
What does the filter pressure gauge read? When was the last time you cleaned the filter cartridge?
If you can feel a strong flow of water coming out of your pool return eyeballs, then it would most likely be the flow switch.
Thanks for posting,
