My Cuisinart coffee maker DCC-1200 turns off by itself at various times. When it was new it never did this?

The machine is probably toast - but it's covered by Cuisinart's three-year warrany. Customer Service: (800) 726-0190. They charge $10 shipping, unless you live in California.

Turn the function knob to Auto Off
Hold down the hour button til you see the clock display blinking
you can then use the Hour and Minute buttons to program how long you want the coffee maker to stay on.
You can choose from 0 minutes (seems to be what you have it set on now) to 4 hours.

SOURCE: How to use the self clean feature of this coffee maker

Hello gerilind,
It is recommended to clean the system out about once a month with a 2parts water to 1 part vinegar, translated it is 8 cups of water and 4 cups of vinegar. Press the self clean button and the brew switch. Rinse with fresh water one or two times.
Should work for you. Don't forget to check the filter stick in the back left of the unit. Pull it out and remove the clogged carbon filters. Shine a light into the bottom of the cavity and clean out the debris left behind. You can get replacement carbon filters on Amazon, they are inexpensive. Reinsert the stick. Your coffee should be back to tasting excellently in no time at all.
I hope this is helpful to you. If it is, please leave positive feedback for me. I will very much appreciate it. Kind Regards, NormanZ :o)

Well, you could try unplugging for an hour. Sometimes that helps, but these have been having a lot of problems (but don't ask their customer service that, they can't admit it but I'm pretty sure they all know it!). I would say call customer service anyway if it's under 3 years old (800-726-0190) after you've unplugged it and let them know what's going on (model and serial # are both located on the bottom of the unit, stamped in the black part). If it's under warranty they can offer you a replacement and from what I hear Cuisinart has been getting in new coffee on demand units (like the one you have) that have fixed the problems. They're on back order right now though, so there will be a wait. Other than that, I would say you don't have many options, unless the store is willing to take it back, because this one is pretty much a goner. Not the first time I've seen it. :(
