A:AnswerIt shouldn’t brew at the same time as far as I know. I’d contact Keurig support. If you put the carafe in, the single serve should be disabled and vice versa.
A:AnswerThis is all I do.....Make sure you filled the water reservoir, put your paper filter and ground coffee in and placed carafe, then hit number of cups and picture of carafe NOT pod and then center button.
A:AnswerThanks for your question. The K-Duo coffee maker is not designed to be directly plumbed into a water line. We hope this information is helpful!
