Dishwasher leaks in bottom center

I have a frigidaire dishwasher that just starting leaking in the bottom center and bubbles were coming out of same area. I checked the gasket around the door, I also checked the seal that is on the inside liner. Checked the float to make sure it is not stuck. It is still doing the same thing. Do you have any other suggestions on what to check for? Thank You very much

Is it a lot of bubbles.

If yes then standard dish soap has somehow got into your unit.
