I had the same problem.

There are 4 rubber "feet" that conceal additional phillips screws. These feet are easily removed by lightly pulling them out of the screw holes with needle nose pliers.

On my coffee maker, the problem was heat sensitivity with an IC marked "53A3P 512AAC". I was not able to find this IC. If I HEAT this part, the coffee maker will briefly work until the IC cools down.

I would be interested in either finding the board, or IC.

Hope this helps.

The clean light came on and I cannot find my manual to find out how to clen it. Plaeas help


Always turn coffeemaker OFF and remove the plug from the electrical outlet before cleaning. Lift up the reservoir cover. Remove and discard the paper filter and ground coffee. The filter basket can be washed in warm, soapy water and rinsed thoroughly, or cleaned in the upper rack of the dishwasher. Dry all parts after use. Do not put any water in the unit once the filter basket has been removed. Wipe the area under the filter basket with a damp cloth. Remove the carafe from the heating plate. Discard any remaining coffee. The carafe and lid can be washed in warm, soapy water and rinsed thoroughly, or placed in a dishwasher. The carafe and carafe lid should be placed on the upper rack only. Do not use any scouring agents or harsh cleansers on any part of the coffeemaker. Never immerse base unit in water or other liquid. To clean base, simply wipe with a clean, damp cloth and dry before storing. Fingerprints and other blemishes on the stainless steel housing can be washed off with soap and water or a nonabrasive cleaning solution. Wipe warming plate with a clean, damp cloth. Never use rough, abrasive materials or cleansers to clean the warming plate. Do not dry the inside of the water reservoir with a cloth, as lint may remain.

Coffee maker shuts off too soon after brewing.


Hello FloydBob, The Cuisinart DCC-1200 has the ability to program the auto-off function that keeps your coffee warmer plate on after brewing is complete.

The unit lets you select the time increments from zero up to 4 hours.

See page 6 of the attached manual for the full instructions for reprogramming the coffee maker.

To program the Variable Auto Off:
1. Turn the FUNCTION KNOB to the “Auto Off”
position. Press and hold the “Hour” button
for 2 seconds. The clock display will start
blinking.
2. Program the coffeemaker to shut off from
zero to four hours after brew cycle is
finished by using the “Hour” and “Minute”
push-buttons.

I figured you might also like to have a complete instruction/owners manual so you can have access for any other questions you might have about your coffee maker, in the future.

Try this and let me know if it works - plug the coffeemaker in, turn the function knob to BREW, and then press all 3 buttons in the center of the coffeemaker (the 1-4 button, et, etc) and hold them for a few seconds. Let me know if the clock display comes back on.

If not, call Cuisinart and see if it is in-warranty by serial number 1-800-726-0190.

Cuisinart coffeemaker DCC-450 switch keeps turning off by itself.


There is a defect with your coffee maker. It uses a momentary switch, but is supposed to stay on for 30 minutes. I believe there is a common failure due to heat sensitivity of an IC on the board. I suspect this is a timer chip. See my other postings on this.

Coffeemaker getting hot but not brewing


The parts to repair a problem of this magnitude are generally not available. The DCC-2000 has a thre-year warranty. I would call Cuisinart and see if you can get an in-warranty replacement. I have a high opinion of cuisinart and their products, but this particular coffeemaker, I do not personally reccomend.

Water won't move from reservoir/showerhead to carafe


You can try cleaning the unit first and if that doesn't work you can contact Cuisinart Warranty at 1-800-726-0190 and see what they can do for you. Do you have the original user manual that came with the machine?

As per my book on my unit (DCC-2000) you can try decalcifying the unit. I have never had any problems with that, but I use filtered water all the time and that may be the reason mine is working very well (except leak) after 18 months of age.

Per user manual....

Decalcification refers to removing the calcium deposits which form over time on the metal parts of the coffeemaker.

For best performance from your coffeemaker, decalcify the base unit from time to time. The frequency depends upon the hardness of the tap water and how often you use the coffeemaker.

To clean, fill the water reservoir to capacity with a mixture of 1/3 white vinegar and 2/3 water. Turn the coffeemaker on by turning the ON/OFF knob. One cycle should be sufficient to adequately clean the coffeemaker. When the cycle is completed and the five beeps sound, turn coffeemaker off. Repeat operation, this time using fresh cold water.


Good luck and I hope this helps your problem.
