Can we get a little more info?
When you pull the handle does the handle pull out and leave the "gate" still closed? That is pretty easy to check with a stiff wire up the drain.
If the handle IS pulling the gate open then you may have the dreaded plastic disk from the hole saw that was used when the tank was installed. The disk washes over the opening thus blocking it. We did and it was the factory that went in to remove said disk.
Good luck and let us know.
