Dishwasher leaking underneath and not draining

Hi. For a few days my dishwasher had a small grinding noise coming from it. Last night I took apart the drain filter and assembly and found a screw and a few pieces of glass in it. I cleaned out all the debris and put it all back together. When I started it, it filled with water and hummed for a few seconds and never went to the next cycle. I turned the drain on and it sounded like everything was fine except it didn’t drain any of the water and is now leaking from the bottom around the center of the dishwasher. I have no idea what to do about this. Any advice would be greatly appreciated.
