Take apart Cuisinart DCC-1100
It can be done, but it's not for the fainthearted.
Simplest: Put tape over the hole above the "clean" buton to the left of the control panel. This will muffle the beeper, which is a piezoelectric disk located behind the hole.
Most effective (Your mileage may vary.):
1) Unplug the machine. take out the filter cone, Set aside the pot.
2) Pop the plastic covers off the two top screws. Unscrew them, set them aside in a container
3) Use a flat-blade screwdriver. Insert it into the two slots at the top back and lever up to pry off the lid at its hinges. slide it off the hinged spigot tube, ans set it aside.
4) Use the flat-bladed screwdriver to pry the top back of the outer case off the two tabs of the top plastic insert part which extend aroudn to the two top screws, freeing the back part of the top insert so that it can then be levered upward.
5) Now, carefully lever up the top plastic insert at the two slots here you prviously pried off the hinged top. What's resisting the upward pressure is a press-fit of the black downtube, which feeds the hinged spigot tube, into the lower part of the hot-water feed. It should pop free, exposing the upper electonics module which is attached to a ribbon cable. The ribbon is held into the case by some white gorilla snot (silicone adhesive). The electronics module is held to the outer case by two screws.
6) Remove the two screws that hold the electronics module to the case. Twist the electronics module around so that you have acces to the four screws on the back.
7) Remove the four screws on the back, and lift off the back. You should now see the backside of a gree circuit board, held in place by one screw.
8) Remove that one screw. Now pry at the edge of the green circuit board to lift it away from the front control panel. You should now see the pizoelectric beeper module, a round can with a hole in its middle located behind that hole I mentioned earlier above the "clean" button. It's soldered onto the circuit board by its two leads.
9) Do you have a soldering iron handy? If so, melt the solder that holds the two leads of the piezoelectric module, lift it off the board, and throw it away. If not, first use diagonal cutters (****) to clip the leads off as flush as possible with the backside of the circuit board, then drill through the circuit board at the leads, so that the piezoelectric module pops free. Throw it away.
10) Now reverse the disassembly process and put the coffemaker back together.
11) Smoke test! Plug it into the electrical outlet. Does it still turn on when you press the brew button? If so, good. If not, go buy a new coffeemaker.
12) Water test. Put about 1 cup of water in and run a brew cycle. does it work OK? No leaks from the bottom of the coffeemaker. If so, good. Enjoy the lack of beeps.
13) Brew a pot of coffee.
