Diagnosis
Water is escaping from an internal connection. The prime suspects are a cracked water reservoir, a failed internal hose connection, or a leaking thermal fuse housing.
How to Fix It
First, rule out overflow. Remove the brew basket and check the silicone gasket and spray head are seated correctly. Then, run a water-only cycle with the machine on a dry paper towel. Trace the leak's origin point.
If That Didn't Work
If water pools from the very bottom center, the thermal fuse housing (which the heating element passes through) has likely failed. This is not user-serviceable and requires a warranty service call or base replacement.
Heads Up
Continuing to use a leaking machine risks severe electrical damage. Unplug it immediately if water comes from the electronics base.
