KitchenAid Dishwasher isn't circulating the water!

[SIZE=4]Help! My KitchenAid Dishwasher is not circlulating the water and it’s just slowwly coming out from somewhere and puddling at the bottom without touching any of the dishes! The steam is working great still and also, earlier today my son and I disassembled it to check if the screen and blade were clogged or blocked which they were with stuff but we cleared it out, cleaned it up and correctly reassembled it-and it still isnt working! What is the problem? Why is the water not swooshin around or the blades not spinning to clean? Thanks soo much for your help! I’m desperate to fix it!:):)[/SIZE]
