Have you tried lifting the pedal?
That's how some of them work.

Nope, this one works by depressing half-way for water to fill bowl.
Have owned the rig for 7 years now and it just started acting up last year, thought the rod was binding on the back of the toilet so shaved away a bit of the area with a utility knife to give a little more clearance and that helped. Not this year though, acting up first time using it. Greasing up the slot does not help.
