Keurig duo

The coffee pot duo does have a very minor intermittent leak from time to time. I’ve never been able to determine exactly where the water is coming from. It’s only a small amount—usually just a few drops, and the most I’ve ever noticed was about a tablespoon after sitting for a few days. It does not leak heavily, and everything else works properly as it should. I usually keep a cookie sheet or towel underneath it as a precaution. When using it, I either fill the reservoir for a full pot or add only enough water for what I’m making. I’ve also left the reservoir empty when not in use to prevent any leaking. I’ve never had an issue with spilling water when refilling it, and I haven’t noticed water coming from underneath the machine.
