Urgent help vectra m1 back siphoning

[txmk4]

My vectra m1 starts then it back siphoning the water in skimmer. Just noticed it this morning I shut the power off open the pump and everything checks out good. When I plug it back in it started doing the same thing. What are my options? I attached the video for reference.

Your description sounds like its not pumping.
