Dishwasher leaking

Dishwasher when running leaks water from the center of the bottom of the door. Already replaced the door seal because it was torn. I checked the spray arm for plugs or cracks and it looks fine. Checked the lower spray arm bearing and it is not damaged. Only thing I see is the front of the inside of the bottom of the tub looks warped. Not sure if there is a gasket, or deflector of some type missing. Thanks for your help.
