Believe it or not, your Keurig K150, B150, K155, and B155 Brewers are equipped with a secret menu from which you can customize more advanced settings of your coffee maker.
To access the Keurig Secret Menu, turn off your Brewer by flipping the power switch. While holding your finger on the middle of the screen, turn the brewer back on. Continue to hold your finger on the screen for 5 seconds, until the Secret Menu appears.
You should now see a bunch of different menu options displayed on the screen.
From here, you can change your preferred Brew Temperatures, customize the Brew Sizes to display on your brewer’s main dashboard, Auto OFF options, On/Off Time, the Clock settings and Language preferences.
