crwdns2890332:0My Keurig makes brewing noises but doesn't brew.crwdne2890332:0I had not used my brewer in about 3 months. I turned it on and the water heated up and I pressed Brew , Nothing. then the water started coming out of the over flow hose back into the water reservoir. My son took a can of compressed air that he uses to clean the computer. Put the hose of the compressed air into the hole that didn't have water coming out of it. As he did this brown water came out of the brewer where the coffee is normally made and filled a large cup. Then we put more water in the tank and he did it again. Not as brown this time. The Brewer now works. brews the correct amount of oz for what is chosen. Thank You Son. works great now.
