There could be several reasons why your Mr. Coffee is beeping and not brewing. Some common causes include: 1. The water reservoir is empty or not properly filled. 2. The coffee pot is not properly placed on the warming plate. 3. The brew basket is not properly in place or is clogged with grounds. 4. The machine is in "clean" mode and needs to be reset. 5. The machine may have malfunctioned and need repairs. You can try to resolve the issue by checking if the water reservoir is full, ensuring the coffee pot and brew basket are properly in place, and resetting the machine by unplugging it for 1 minute and plugging it back in. If the problem persists, please refer to the user manual for further troubleshooting instructions or contact customer support for assistance.
