It was a little quirky setting up right out of the box but once you figure things out you will love the Keurig Coffee maker.
TIPS FOR Keurig Machine n00bs:
You just have to make sure it's full of water and then hit the power button to make it heat up for a while. Then run it a couple of times and it will be ready. It may take a day for the "not ready" indication to go away but it will.
The machine basically heats up the water when you turn it on. Then when you load a "k-cup" (the Keurig style plastic cups full of coffee, tea, cocoa etc.) and close the machine it will flash a small or larger cup on the LCD for you to select the time spent dispensing hot water.
The machines power will turn off after a long while and you will have to turn it on and wait for it to warm up again when the time comes that you desire another cup. There is a programmable timer so that your machine will be ready and warmed up when you wake up or whenever.
