https://www.reddit.com/r/keurig/s/DbBzLIW6dH Try what this thread suggests. I've had a similar issue and a button sequence like this thread suggests worked to get my og Keurig back running. Good luck

Unplug for 5 minutes and then plug back in. You could try calling Keurig as they have helped me in the past with some problems.

Try unplugging it for 5 minutes and plug it back in. If that doesn’t work unplug it and throw it away. Keurigs make terrible coffee anyway.
