Dishwasher Puddle

Attachment 50477 (http://www.doityourself.com/forum/attachments/electric-large-kitchen-home-appliances/50477-dishwasher-puddle-20150513_014826.jpg) I have not used my DishWasher for over 12 years. Recently, we had the kitchen remodel and the only thing left that has not been replaced is the dishwasher. Today, I changed out the air gap hose and the garbage disposal hose since we just got a new garbage disposal. I decided to run the DishWasher and checked for any leaks. No leaks under the cabinet. However, I noticed a small puddle of water under the DishWasher next to the discharge hose at the end of the cycle. The water was actually running down from the vertical coil spring (shown in picture), not dripping from the discharge hose or main water line. Is this condensation and is it normal or do I have some type of leak that needs to be fixed? Thanks
