If the light is green the pump has vacuum. You likely have a clog.
First place to check is at the throat right below the ball.
Turn off water, leave pump on. Use a long stick or similar and probe. If no luck go to plan B.
Leave water off, pump on. Grab a plunger, oven the valve and insert plunger and try to get a good seal. One stroke down then break suction with fingers, long screwdriver, etc. Repeat as needed. With luck...
Some say you can plunge away, but IMO you stand a chance to mess up the duckbill valves.
NEVER any female sanitary products in the toilet. Large deposits, I use a two flush system. Deposit, flush, paperwork, flush. Use plenty of water.
I never have tried a snake, but no reason that it shouldn't work unless the clog is at duckbill valves, and it would be a moonshot to get it through the accumulator tank.
