When my Maytag (model MDB7100AWW) dishwasher runs sometimes a little water leaks out the bottom middle of the door. The gasket is not in great shape, but the leak isn't near the sides. There does not seem to be a gasket on the door bottom. One suggestion is the gasket or the soap dispenser latch gasket. Any thoughts?

The door gasket is $55, and I am not sure I want to spend that on a 10+year old dishwasher.
