Question about Cuisinart DCC-1200 Coffee Maker
The problem may be caused not by a check valve in
the inlet hose. This little gadget, about an inch inside the heater end
of the tube, allows water to flow into the heating element but not back
-- unless it's broken. This hose is the one closest to the outside edge
of the bottom.
I'm sure *someone* must sell a replacement part, and I'm in the middle of that search. But I did get an older, broken coffeemaker from my brother (another member of "the Slow Wastebasket" society!
I was able to disassemble my Model CBC-00PC2 using a standard Torx 10 screwdriver. However when I tried to take apart an older model, DCC-1200, I found that it used the security version of the Torx 10 screw: it has a tiny nipple (correct word?) in the center of the screwhead that prevents a standard Torx driver to fit. I was unable to find the correct screwdriver and a security Torx bit is too thick to fit, so my brother and I resorted to brute strength to pop of the bottom.
The only other problem I had was that the older hose was a bit brittle and both the older and newer ones had sort of welded themselves to the aluminum heater element tube. Luckily, there was enough extra length and I was able to make it fit -- barely! I lost one of the little metal clips so substituted a tiny cable tie.
Everything seems to work. Oh, the only reason I knew about the check valve is that I previously disassembled the thing to see what was wrong and I found something (probably a piece of the valve!) floating around.
Hope this helps.

Disconnect the coffee maker, take carafe, filter and filter holder out. Lie the coffeemaker down over on the the side of the sink with the back of the coffee maker facing away from you, the top over the sink, dip stick removed and facing down towards the counter-top. Look inside the reservoir and you should be able to see the hole where the water enters the heater. The coffee grinds get stuck in that opening and cannot get out. Solution: I used two plastic straws joined end to end. Then used water from my mouth blown in through the straws to flush out the hole. The water flushes the grounds towards the sink. After a few mouthful flushes, shake the coffeemaker and more grounds begin to emerge. Repeat till the hole is noticeably clearer. A headlamp or bright flashlight helps immensely to see the intake hole with (before) and without the grounds (after). Reassemble and run water through the coffeemaker. I was able to get 5 cups out in 4-5 minutes. Previously it took 20 minutes.

I have the same coffee maker - only a few months old - and same problem. I forgot to put the carafe back under the machine one day, turned it on to brew, and the coffee grounds backed up inside, getting the reservoir dirty.
I don't think it's a broken part - I think it's just clogged, like toilets or drains get clogged. I'm trying to figure out a way to flush out the grounds in there. Vinegar is good for calcium buildup but doesn't dissolve grounds, obviously.
