leaking dishwasher

dishwasher leaking water from the motor. sears parts direct told me my pump was starting to go bad so i replaced the pump and i replaced the drain pump cause it was starting to stick and i would have to beat on it to get it started. got it back together still leaking from the bottom of the motor. so i replaced the sump and seal assy. got it all back together and it is still leaking. water is dripping steadily off of the bottom of the motor when the motor starts to run
