Dishwasher Trouble

This house that we are renting has a dishwasher. Even since we live here, I have only used it a couple of times. I believed that something is wrong with it, cause it seems like it is not working right, and it makes funny odor and noises.  It was my first time to used a dishwasher though, so I have no idea if that is normal. Hubby said that we need to get a kitchenaid dishwasher repair before we used it again, cause this might cause us some major problem in the future if we keep on using it. I hope it is okay, so I don’t have to wash the dishes by hand, and in order for me to save time.
