Cuisinart dgb-650 DGB-650 Series 10-cup coffee maker. Only about 6 weeks olds. We do have hard water. The maker is not brewing the all the water put in. The 1-4 cup feature is NOT turned on. It leaves anywhere from 2 -5 cups left over. The beeping at the end of cycle is not just 5 beeps anymore is beeps for much longer, maybe 60 seconds?

I just called Cuisinart and they will send me another brew basket for my DCC-100 (it has a Brew Pause valve also) for $9.14 (part + S&H). Did you try to contact Cuisinart?

SOURCE: My DGB-500 Cuisinart Grind & Brew coffee maker leaks coffee

I found out that internally the water line that comes off of the heating element is made of a rubber/silicon material. The heating element is so hot that it scorches or dryrots the tube and it cracks causeing leaking. Sometimes it comes pouring out and other times it just is enough to make it a pain. I have taken the time to get my specialized screwdriver set and take off the bottom of the pot, but have not been able to find a replacement tube for it. (They also made the tube so that you dont have enough to cut the broken end off and put it back on and if you COULD do it, they also put an "X" in the original tube so if you cut it and try to put it on you cannot push it on far enough. Other than this, it was a great coffee brewer for me for the past four years. (Put baking soda and water paste on the coffee stain if you have formica counters. A few times of doing that and the stain will come clean)

you need to run a few pots of straight white vinegar through the machine to clean out the lime build up in the tubes. the first time you do it, after it starts to pump the water, shut it off for a few hours and let the vinegar sit in the tubes. after doing this run a few pots of cold water through before making coffee.
