KitchenAid dishwasher leaking from bottom

Our KitchenAid dishwasherMOD:KUDE48FXSS5 is leaking from the bottom. It appears to leak when filling and is coming from the middle center. It’s hard to tell where the leak is coming from since we’re peering under it while it’s running in order to see the water. It starts leaking as you hear water filling, then stops for a few seconds after the initial rush of water stops, and then begins to leak again. Would like to replace ourselves and save money but not sure what part may be the issue. Video here: https://youtu.be/2Spj1QoV1Yc
