Frequently Asked Questions

Why does my Keurig machine say 'drip tray full' when it isn't?

This error is triggered by a float or optical sensor in the drip tray, not by the actual water level. 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 Drip Tray Full Error guide — most are cleared by a power reset or a descaling cycle.

My Keurig K Mini keeps showing the drip tray full error — fix?

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 Drip Tray Full Error guide lists the codes and their fixes.

How do I reset the drip tray sensor on a Keurig machine?

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 Drip Tray Full Error guide.
