I have an older Keurig 2.0 that is leaking hot water from the bottom. It’s not the seal at the Resevoir like many suggested. After taking the cover off I found it is leaking around the boiler unit where the top plastic cup mates to the bottom metal cup, which is held together by screws. All the parts in the machine are still like brand new, pliable and free from any obstructions, or scale. I haven’t taken that until apart yet to see if it can be fixed, but apparently no one else has had this problem since I can’t find any information pertaining to the boiler, or heating tank, so I guess I’m on my own with this one!
