Frequently Asked Questions

A blank display with the machine still running usually points to the control board or its ribbon cable. Error codes on Keurig machines usually point to a specific condition: a full drip tray, an empty water tank, a stuck brew unit, or scale buildup. The most common codes are listed in our Display Not Working guide — most are cleared by a power reset or a descaling cycle.

A code on the Keurig display is the machine naming its own fault. Start with the easiest fixes: reseat the tank, empty the drip tray, and power-cycle the machine. If the code returns, our Display Not Working guide lists the codes and their fixes.

Most Keurig error codes are warnings, not hardware failures. Check the drip tray, water tank, and brew unit first, then reset the machine. The common codes and their exact fixes are documented in our Display Not Working guide.
