I agree that it sounds like it is clogged. If u have a tee with a cap like beans design then u can take the cap off & try to run something down the pipe to unclog it. That is the reason bean used the caps in the design, so hopefully u don’t have to take the plumbing apart to get it clear.
If it isn’t draining much & u don’t have bubbles exiting the syphon into the sump, then chances are it is clogged.
