Error:
This is condensed water and not something that you need to be concerned about. The drip tray is designed to catch the runoff from the brewing purpose, but it is normal for condensation to form underneath.
Solution:
Make sure you insert the drip tray with its cover to catch any runoff. This should prevent the brewing process from becoming messy, and protect your countertops.
If you find water drips into the inner floor of your appliance when removing the drip tray, it is being removed too soon. Wait a few more seconds before removal.
