no you have a clog or the water is not turned on .
No priming , your not priming a pump it is just an electric water valve.
Take bottom panel off and loosen water line to water valve but most definatly not a pump issue or a priming issue.
And yes if line was 100 feet long when you turned the water back on it would have possibly trapped some air but the water valve is opened for two min. so that air would have been purged out.
