new tub now washer won't work

i changed the tub out of my whirlpool washer(model wtw6200vw0) because it was making a loud roar during the spin cycle cause the tub comes with the bearings. i didnt realize i would have to completely disassemble the entire washer to do this. after changing the tub and reassembling the washer it wont go in to the wash cycle. it times down till it fills up (from 47 to 41 minutes) then it drains the tub and the display shows 3 minutes and it just sits there and hums. also when it starts to fill it makes a weird noise while its filling. i double checked my wiring connections and everything was plugged into the right spot.the motor on this washer is almost flat, i’ve never seen one like it. i had to take it apart and put it back together on the bottom of the new tub.i would appreciate any help anybody could give me.:slight_smile:
