Dishwasher was not draining

We pulled the dishwasher out completely, drained water that was in the dishwasher. Tilted the dishwasher and the part we needed to replace (Pump Drain Assembly) was in clear view. We used a screwdriver to take out a few screws and replaced the Pump Drain Assembly with the new one. Put the dishwasher back in and proceeded to wash dishes in the now fixed dishwasher. The part was very easy to change out.
