Clean up high to let grime fall down to the next surface. Eventually you will have all the dirt on the floor at which point I highly recommend a robot vacuum/mop with self refilling/cleaning base station.
You should look through the racks to confirm that dishes with the most grime are accessible to jets. Keep dirtier items closer to the jets (near the center typically). Seriously, look up a youtube video.
If you have night dry or don't experience water spots, consider switching Extra Dry features off. These typically have a heated air dry mode at the end of the wash which will decrease the lifespan of your dishes.
If you find your dishes are effectively washed from regular use, consider using the "Express" mode which may decrease the amount of water and max temperature and duration of the wash while possibly yielding the same results.
If you have a top-down washer, you can prevent an uneven load by putting the heaviest items in at the bottom (jeans and towel). This will keep the center of gravity lower and reduce knocking.
It may also help to place these longer items in a loose ball so they don't wrap around the center post and stop the drum from spinning.
Allows the pockets and interior linings to dry off sooner.
The little beads of fibers you see after you've washed a garment a few times occur when the material is rubbed up against other articles during washing. Turning the garment inside out will reduce the amount of friction as the material should primarily rub against itself.
Consider "delicate" for most clothing options. Remove synthetics that dry early. Hang dry buttoned shirts (I usually just put them on hangars on a rack)
