1.  the big handle on the silverware basket is a nuisance & gets in the way of loading the basket.  it was on the right hand side of the dishwasher that is to the left of our sink which made putting itemse in the basket tricky.  i figured out that i can move it to the left side which makes loading easier.  
2. not enough wider spaced slots.  our plates are "deep" and i can't put the plates in each slot so i have to put them in every other slot.  there are more narrow slots than wide ones .  
3.  i did not realize this dishwasher doesn't dry the dishes the same way as our older one. i have to open the door part way  to air dry the dishes.
