Keurig B60 coffeemaker stopped pumping water

This morning my Keurig sounds like it begins to pull water then stops. I tried to cut it off then back on. Still didn't work.Removed water from reservoir and K-cup and added pure vinegar. Ran machine several times without filter or Kcup by pressing cup selector several times. You must open K-cup holder and close each time. I had to do this about a dozen times before the water began to draw again. Flushed system by filling water reservoir with fresh water, and brewed just plain water until vinegar was gone.Works like brand new.

The Keurig B60 wouldn't allow you to brew anything when the "Add water" is lit on the display.

You have tried without K-cups?

If yes and it still is a problem, it might be clogged somewhere. I.e residue from minerals. Try to rinse it with vinegar according to this:
