Clear water is hard to trace.
This is what I would do to trace a leak in my dishwasher.
Take off the lower kick plate so you can see under the dishwasher.
Start/run and empty load.
Once the water is full and just starts to wash...open the door and add several drops of food coloring or a simple package of koolaid (add your own sugar type) bright red color or dark blue.
Then let it run for a bit and discharge the water and stop the cycle.
This should help you locate the drip/leak.
This may be as simple as a door gasket getting dried out and not sealing, but until you trace the leak it will be hard.
Best of luck.
