Stopped guessing on motor rotations and now my jobs go smoother

I always had trouble with dishwasher pump motors spinning the wrong way. It meant taking things apart again. So, I made a habit to mark the rotation direction with a marker before removing the old motor. Now, I just match the marks when putting in the new one. No more second guesses. Jobs finish faster, and I look more skilled. It seems so obvious, but why didn't I think of it sooner? Just a small tip that saved me a bunch of time.
