Dishwasher wont pump at the right time

I just replaced the motor/pump on my GE because it was leaking. the new motor is an upgrade from the original - now the dishes do not seem clean and at the end there is water in the dishwasher - it did not pump out. It almost seems like things are out of sequence. Has this happened to anyone? Thanks

Need more info.
A Model Number may help.

now the dishes do not seem clean
Is the motor running during the wash?
Are the lower spray arms moving during wash?
Is the wash/drain solenoid up or down?

Did the wash drain solenoid activate?
Did the motor run when it was supposed to be draining?
Did it pump out and then water siphoned back into the unit?

Plus anything else that you feel would help diagnose this.
