Question about Cuisinart DCC-1200 Coffee Maker

4 Answers

When brewing, it steams and spits the water out

I adopted this Cuisinart DCC-1200 coffee maker. It was very dirty and appeared to have overflowed coffee grounds when brewing and never cleaned up. The first thing I do is try and run some drip coffee maker cleaner through it. It never finishes brewing....all the time it steams and spits the water through. How can I fix it?

    I didn't adopt it, I bought it new. It worked pretty well but suddenly the water won't go through it, it spits and steams and the grounds make a huge mess everywhere. Seems like the thing is clogged or something. My $25 Mr. Coffee never had this problem; for this price shouldn't we expect a little reliability?

    I have the same problem. In fact, I am currently brewing with vinegar and water as one last ditch effort. It's still spurting everywhere and it's the second run-through. Thankfully, we have another coffeemaker to use as I think this one's had it's last brew.

    It was a great coffeemaker when it was working but it sure didn't last very long. Such a shame.:(

    We have the same problem and have been running French Press. Any solution...self clean, vinegar, etc. and no success.

This is what happened to me, I didn't have the filter basket all the way down so the pot lid didn't open the valve that lets coffee flow so the coffee and grounds ran into the water resevior and plugged the filter, so I did the worst thing possible and took the filter out so the grounds got into the check valve that keeps the hot water going in the right direction. that makes it spit and sputter and brew slow.
after trying to flush it out forever I tore the metal plate on the bottom off and unhooked the rubber hoses (don't do this unless you have a needle nose pliers, you'll never get them back on) one should go to the brew head and the other is the water inlet, this has the check valve. you can tell which is which by blowing through them and seeing which one goes to the brew head. if you can blow through the other one the check valve is stuck open, I blew air into it with an air compresor and this forced the check valve shut and now it works fine. I know this is the same symptons as calcium deposits but I had cleaned it twice.
try flushing it with water first but sometimes it takes extreme measures

    Adding to what klclemon did, I removed the bottom of the unit (held on with 4 small star head screws) which exposed the orange colored tubing. I located the tube that went to the water reservoire, one end of the tube is held by a spring clamp that can be loosend with small plires. I then pulled the tubing off the nipples. I blew into both ends of the tubing and both ends seemed to be restricted. I didn't think it was calcium since the coffee maker was only used about 6 or 8 times. I then pushed the check valve out of the tube with a dowel rod.

    the check valve was clogged with a gooy lint looking substance. I cleaned the valve,pushed it back to its original position and reassembled everything. It now works great. If it wasn't for klclemon's post I probably wouldn't have tried this and would have spent alot of time trying to deal with Cuisinart. Thank you, klclemon

    RE: Clogged Cuisinart DC-1200 hose and check valve cleaning

    The cleaning procedure described above and below works. Here are a couple of additional observations.
    1. Bottom-plate screws: our two front screws required a T10 Torx driver, but inexplicably, the two back screws required a T9 driver. Go figure.

    2. If possible, first try to avoid detaching the ends of the two hoses where the spring clips attach to the heating element (the hose running from the bottom of the built-in water filter contains the check valve).

    3. Instead, simply pull both hose ends (from the bottom of the input reservoir and the second hose, which runs up to the output nozzle). Use canned air to blow in one hose end, through the metal heating element and out the second hose's back end. Be careful to direct the outgoing hose into a clean sink so that you can see any grinds debris being ejected. We did not try to remove the check valve from inside the hose.

    When I loosened and removed the spring clip for the input hose, I found that the hose would not budge, even with plyers. Instead, the plyers cut a gash into the hard, brittle rubber hose. It seems our hoses were fused to the metal. We ended up having to tear and cut away about 1/4 inch of damaged hose and scrape the remnants off the metal heating element nipple. Since our broken hose already was detached, we cleaned the line with canned air (and by smacking the hose against the side of the sink a couple of times and the running tap water through it. Some debris still came out. Fortunately, after cleaning and re-trimming the rough end of the broken input/check valve hose, it was just barely long enough to fit back onto the nipple and still be clamped into place. Barely.

    We then turned the Cuisinart upside down over the sink and thoroughly rinsed out the water reservoir from the top using the water faucet's spray wand (just to make sure no lingering grinds could be flushed back into the system). Finally, we ran four more cleaning cycles, during which a few more grinds still made it through to the glass carafe (but fewer pieces with each successive cleaning).

    Only then did we re-install the bottom plate.

    Adding to what klclemon, tinlvzy, and hdboy contributed above. I had the same sputter and steam issue with my DCC-1200, which only occurred after a routine cleaning process of:

    a) vinegar & water
    b) Urnex powder

    I believe what triggered the issue was that I use a gold filter when I brew coffee, but use Trader Joe's unbleached paper coffee filters during the cleaning process -- the idea being to catch any mineral deposits and debris, and not damage the gold-plated filter. However, once I was able to remove the check valve and see how badly clogged it was, it appeared that the culprit was 99% paper filter related -- see photos.

These coffee makers are just junk. ours lasted all of 3 mo. before this problem began. the best solution is to buy something else.

  • hdboy Jul 03, 2011

    These are great coffeemakers, not junky at all. Ours has lasted two years, but like others described, we accidentally spilled grinds into the water reservoir. Sleepy clumsiness, not a poor product, was the cause of the problem. See the instructions to take apart the bottom plate and clean the water tubes and check valve.

Thank you klclmon and hdboy, with the combination of your advice, I was able to resurrect my coffeemaker from sounding like a steaming sputtery dragon that took half and hour to make 4 cups of coffee, to the coffee maker I used to know. Definitely do not attempt without a needle-nosed plier. I just blew through the tubes and rinsed them out plus flushing the reservoir. I only disconnected them from the heat element, it seemed unwilling to come off the other end and I didn't want to force it. Turns out I didn't need to. I appreciate your posting the solution.

Make sure the 1-4 cup setting is not activated. Try running 2 cups distilled white vinegar and 2 cups water through it to see if it will brew all the way thorugh.

Here is a link to the manual:

Coffee tastes like plastic!

We have had our DCC-1200 for 3 months. The plastic taste occurs about every 3rd pot, and it does NOT get better. We've wasted over a pound of coffee. Cuisinart says we are the only people in the world with the problem. Well, I guess not...

Unplug for 20 minutes or longer to reset. Make sure the lid is on the caraffe, or the brew basket will be stuck in the closed position. If the water still won't go through, consider ordering a new brew basket, because yours might have a faulty spring.

Dcc-1200 not working

Probably dead, but:

Here is the basic troubleshooting for the Cuisinart coffee makers:
Make sure all baskets are in proper place – especially if unit is beeping.
Do not use a paper and a gold-tone or other permanent filter at the same time.
Unplug for LONGER THAN 15 full minutes to reset.
Clean by brewing 2 oz of distilled white vinegar/2 oz water.
If these methods fail, the unit probably requires replacement – call Cuisinart as they have a longer-than-standard warranty.

Coffee maker brews too hot

The 1-4 setting makes the coffee extremely hot. If the 1-4 setting was not activated, make sure you are not using paper and permanent filters at the same time. If you are not using them at the same time, it is time to clean the coffee maker out with 2 cups vinegar and two cups water.
