Anyone know wtf is wrong with my dishwasher?

We left for vacation a week ago and I let a load go while we were on vacation. Then I came home and the dishwasher was making some noise and we noticed a little water on the floor, so I just cut it off. Then today I went to look at it and thought it was just a bad seal that caused something weird to happen, but it's still doing this even when the door is open. It's a 14 year old Bosch dishwasher. Anyone have any clue wtf is wrong and how I can fix it?
