I had this same problem and found that coffee grounds had somehow gotten in to the water reservoir and had been circulating thru the machine clogging the charcoal filter. This must have prevented the water from entering the heating chamber efficiently and therefore continued to gurgle until it all got thru. I flushed out the reservoir by holding the pot upside down and shooting water into the reservoir. It took some time to get all the grounds out. I took out the charcoal filter, flushed out that section and replaced it with a new filter. When finished, I ran thru a solution of white vinegar for good measure and bingo!! The coffee pot works perfectly.
Cuisinart Brew Central Coffeemaker DCC-1200 Series
Steaming, gurgling, and slow coffee production
My Cuisinart DCC-1200 started to slow its brew time, gurgled non-stop, and steamed up my kitchen. Visiting numerous self-help repair sites, I read about vinegar treatments, CLR flushes, and flushing the water chamber to clear any stray coffee grounds.
First I started with the easy process of flushing out the water chamber. No luck. Then I moved on to performing a couple of vinegar "self-cleaning" runs, the gurgling continued. I then graduated to a 50% strength CLR flush, the gurgling and steaming continued without change.
It was time for surgery. One post that I read suggested opening the bottom base plate and snooping around. Here's what I learned that worked.
1.Open the bottom base-plate on the DCC-1200 unit using a T10 Torx precision screwdriver (less than $5 at your local hardware store). You will need to loosen four (4) screws - two built into the feet and two found on the opposite ends of the base plate.
2.Check to see if the electronic wires are clean and intact. Mine were. No electronic issues for me.
3.Locate the two dark-orange colored flexible water tubes. One tube pulls water from the water chamber (reservoir) routing it to the heating element. The other routes hot water from the heating element and circulates it to a pipe that connects to the shower unit above the coffee basket.
4.Feel along each of the two dark-orange water tubes. One may contain a hard section where an in-line plastic filter unit is located. Remove this tube by loosening each end. Note that the end connected to the heating element may be a bit more difficult to remove as it may be melted onto the metal section it covers. A little tugging will release it. Don't rip it, be gentle and it will eventually release.
5.Push the in-line plastic filter unit out of the tube and inspect it. Mine was roughly ½ inch long, made of white plastic, contained a small round ball much like a small ball bearing), and several pieces of large coffee grounds. I removed the coffee grounds and made sure that the small ball was re-inserted into the center of the filter unit.
6.Push the plastic filter back into the dark-orange flexible tube and reattach it to the two connections on the coffee maker. Reset the bottom plate in place and line up the four screws. Tighten the screws with the Torx T10 - the screws strip easily so don't overdo it.
7.Flip over the unit and make your coffee. My result was that the unit returned to normal coffee production - no gurgling, no excessive steaming, and its normal production time. The brewed coffee tasted better as well - probably due to the earlier vinegar and CLR flushes.
8.Happy coffee break to you!
Thanks for the information, Mark. You provided the solution to our problem. Some big chunks were in there! Removing the base screws was the hardest part of the process. Our coffee taste better too after all the vinegar and CLR flushes...and the better flow :) ~Mike & Susan
I removed the hose from the heater side and removed the one way check valve (the little ball in a a cage). It appeared clean but I made sure it was operating rinsed it and blew out the hose without bothering to pull it off the reservoir side. Even though there was no indication of grounds in the line, It now works fine. I can only assume the check valve was not operating as it should have and cleaning it under water may have helped.
Agreed....worked great. Be careful when removing the check valve from the tube as the ball can fall out and get lost easily. Pour water into the tube, then blow it out to ensure clean. While I was in there, I went ahead and pulled the other tube out and did the same (no check valve). Works like new again.
I tried it but the hose wouldn't come off the metal tube without tearing; so I just blew air in the other end, and poured water in there and blew that out, and it did help. Then I went back to do more and the hose broke off the pipe. Argh. I cleaned the pipe and reattached the remaining hose, which was long enough. Now it gurgles a bit as it puts out each splash of hot water, and a bit at the end, but not on-and-on like before.

We have the same coffee maker and had the same gurgling problem. Water pours into the right rear. Eventually discovered the filter inside a long plastic piece in the left rear, opposite the water reservoir. cleaned out the coffee grounds, replaced the filter, and the coffee maker responded like it was brand new.
