Dishwasher repair

My dishwasher has been leaking for a few weeks and the last couple of days it got really bad. My plumbing experience is pretty limited. I've replaced some faucets and toilets. That's about it. I took the dishwasher out using instructions I found online, replaced the dishwasher elbow, tightened it up, hooked the water back up, and tightened things until the leaking stopped. Not too bad. I think I could replace a dishwasher by myself, with instructions.
