Chosen Solution

Stupidly plugged it into the outlet in Beijing, it made a buzz sound and has never worked since. That was a year ago. Back in the US and would love to fix and use it, especially since it was brand new when I messed it up. Thanks!

Plugging into China’s 220V outlets probably burned out the power supply or transformer in the Keurig. I’m not sure if you can get replacement parts for that, but you could check on Keurig site.
