Toilet Valve opens early

Question

Can't find this exact problem listed anywhere.  As you know, the toilet is designed so that when you push the foot lever just a bit, that should open the water valve, then push it to the floor to open the toilet valve to dump the waste into the black tank.  Just recently on mine, the valve at the bottom of the toilet opens right when you push on the floor lever.  The water valve still works fine, but there is no way to let any water in and keep it in the bowl as the dump valve opens right off the bat too.  Anybody run into this problem?

What brand do you have. On our Thetford there was a loose hinge clip that slowed the valve to open before letting water in. Kind of hard to repair in place but can be done.

Have you tried to LIFT UP on your peddle after you flush,when you do that you can put as much water in the bowl as you want.

It is a Thetford toilet.  Should be able to push about halfway down to let water in without opening the waste valve at the bottom, then push all the way to open that waste valve.  Seems like I would need to remove it and maybe look under it for something that came loose from the foot lever?

Thetford has 6 or so models with foot pedals....

Pick your toilet, then click on manual. It will have exploded view.

Could be pinched cable, loose clip, bent rod...depends on which model

Should be able to correct in place.
