dishes not getting clean & sprays plugged with food particles

Food chopper ( plastic splines and plastic splines on motor worn down) motor replace. Bad thing is my motor was good and had to buy new motor because the $20 part comes with motor. But all in all easy fix. Never even turn off the water but did unplugged the electric. PS. Did tell wife it wasn't a garbage disposal. O she takes care of dishes, doesn,'t trust me too do them.
