There are two possible problems with your Keurig. The magnet in the water reservoir is out of place or the auto off timer has been is set. To check if the magnet in the water reservoir is out of place remove the water reservoir and lid, and then use your hand to realign the magnet. To check if the auto off timer is on, press the button below menu and scroll through the programming options. The auto off timer should be set to “off”
