Cuisinart coffee maker gurgles and water steams

SOURCE: Cuisinart DCC1000 coffee maker

At the bottom of the reservoir there is a hole the water flows through to the heater. When my coffeemaker did what yours does it was because a little valve that sits in that hole had popped out, and after tamping it back in it solved the problem. The valve is supposed to keep the hot water from going back up into the reservoir. Without it the water backs up, causing the steam to shoot up as you know, and heats up the water in the reservoir. This causes the thermostat to turn it off prematurely. The valve can come out of the hole either if the coffeemaker is turned upside down, or if there is a major buildup of mineral deposits that need to be flushed out -- they can overheat and cause too much back-pressure to the valve. Flush it with vinegar and push the valve back in as tight as you can, then be careful if you turn it upside down.

SOURCE: When brewing, it steams and spits the water out

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

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.
