Your Keurig has a tiny water pump that works hard. If it gets air in the line, it can lose prime. That means it hears your command to brew, but can’t actually push the water. It’s basically a broken heart for your coffee.
To fix this, try a “reset brew.” Fill the reservoir, take out the K-Cup, and run a water-only cycle. Sometimes the pump just needs a pep talk (or a little water pressure). If you hear a loud gurgling noise, that’s progress—it’s burping the air out.

Fun fact: some Keurig pumps have a maximum cycle count before they give up. They’re like tiny, caffeinated hamsters on a wheel. They eventually wear out.
