I have had the Cuisinart DGB-600BC for a bit over a year. The coffee grinds, and then sometime during the brewing cycle, it will go, "beep beep, beep beep, beep beep..." on and on.
I think I have traced the problem to the latch on the top lid that you open to access the bean hopper. I believe the latch sticks and doesn't close the lid tightly enough. It will appear to be closed, but the latch isn't all the way in place.
So, there is a small screw on the inside of the latch in the lid. Carefully unscrew this, remove the screw, latch, and the small spring. Remember which way the latch faces.
With a warm damp paper towel, clean the latch and the slot in the lid that the latch goes into. Reassemble, and make sure the screw is not so tight that the latch doesn't move freely.
This should solve your problem.
