Dishwasher Features

I am looking for a new dishwasher and would like other people's opinion on features they would recommend.

If anyone can help I would appreciate it. My old dishwasher leaks and I am really getting tired of doing dishes by hand :-)

Have you had anyone look at your dishwasher, my sister in law did her dishes by hand for several months and then they called a repairman to look at it (after they heard it might not be that expensive) and it only cost about 50 dollars to fix it.

No I haven't looked into it. My dishwasher has been repaired over and over again and it is so old and outdated parts are getting a bit hard to find. It is time for a new one.

Still I would like to know a bit more about what features I should look for. Like what types of racks are good to have and what not.

I am also up in the air about silverware racks. I have seen some on the door and some on the main lower rack. The door rack seems to be a good choice in that it saves space but not sure how well they will get cleaned. Any ideas?
