Why doesn't my thermal carafe keep the coffee hot any longer?

No mention was made as to how old your unit is. A thermal carafe is only as good as the vacuum seal surrounding the carafe. Have you run your carafe through a dishwasher? If so, you may have liquid in areas where there should be only air or vacuum. The thermal break is gone, coffee does not stay hot. Another consideration, is the brew temp where it should be in the first place? Fouled heating elememts do not heat the water to the same high temp as clean heating elements will. Clean the elements by brewing a pot of white vinegar. It is amazing how much color (crud) the vinegar will pick up. After the vinegar, run at least two or three pots of clean water. I sometimes will run do the vinegar treatment twice. These are only guesses and not answers, but your question could be answered in so many ways. I wish i could help more.

With respect, BJRohner's answer is incorrect. The carafe on this model IS a 12 cup thermos, and should keep the coffee hot for several hours. That's one of the benefits of this unit: it doesn't need a "burner" under the coffee, and can't produce horrible burnt coffee. If you've noticed a change in its performance since it was new the vacuum seal is probably broken, and the carafe should be replaced.

Never did keep it hot - the carafe is just lightweight and only good for a few hours. Rinsing your carafe with hot water before brewing helps it say hot longer. I transfer the coffee to a great 12 cup thermos since I take it to work which will keep it hot for up to a day.

I would take everything apart in the brewer and the carafe and clean as thoroughly as possible. Pay extra special attention to the carafe lid - make sure the gasket is still fitting snugly and that there are no grounds trapped in the vacuum area.

The coffee is hot but not too hot to sip after pouring a cup. Also, if the carafe leaks around the top, contact Cuisinart and they will replace it. At least they did for me.........

We bought this same model in January, and coffee percolates only to a warm first, second, third cup. Only with a small amount left in the pot, heating for over an hour, does it get hot.

Well...You are welcome...and Congratulations on figuring it out...I strongly suggest pre-warming the carafe with hot water before brewing. That's the only way we get hot coffee from the carafe. ENJOY! Heck, I think I'll go make myself a cup of coffee.

Not that I am aware of, but the carafe did not seem to get hot when using the single serve side only.

The carafe is not insulated. It's made of rolled sheet metal and heat will dissipate quickly if not maintained by the base. I've found the digital temperature system difficult to manage. I connected it to a switchable power strip so I can turn the whole system off after each use. I don't use the keep warm feature. The water continues to heat up so I just shut it off completely using the power strip. It would be nice if it indicated when the set temperature has been reached with an audible beep or tone. Ultimately, I'm disappointed with the digital temp system. The unit continues to heat the water after the set temp is reached even though it tries to enter the warming mode.

The thermal carafe will not reliably keep the coffee hot for more than 2 hours. BUT, it never lasts more than 30 minutes in our house so it has never been an issue.

I think you can be as satisfied with a glass carafe. There is a noted decrease in temperature using the thermo carafe after the third cup. Have you noticed how quick the coffee maker shuts off after brewing? I think that contributes to the reduction in temperature and I have experienced your problem. At times I have just turned on the maker without adding any more water. On other occasions, I have made another pot. The carafe for the thermo pot is difficult to clean. I have tested the temp and it has registered 202 degrees at the first cup. One of the reasons I purchased it.

First cup is HOT w/o pre warming carafe but the remaining cup or two do not stay hot even with pre warming

Everyone who has answered is wrong. The thermal pot has a warming plate that heats up during the coffee brew cycle to heat to carafe. It shuts off when the coffee is done brewing to prevent the burnt coffee taste of normal hot plates. This keeps the coffee warmer longer.

a few hours with a mostly full pot. Longer if I preheat with boiling water. No longer than the thermal carafe that came with my coffee maker.

Sorry, I bought a spare carafe some years ago after I broke the original washing it. So far so good on the one I received when I purchased another coffee maker. Good luck in finding one.

I have had no issues with the Carafe leaking. My only issue is that the coffee does not stay hot very long

I've never had that problem. We've had the coffee maker for about 60 days, the coffee has always been hot, at the perfect temperature.Michael

I'm sorry. Mine does that also. It only brews a couple of cups and shuts off completely. I kept turning it back on until it got to be a nuisance. So now I make the coffee in the glass carafe and transfer the fresh coffee into the stainless carafe when it is done. The stainless carafe has a magnetic bottom so the machine "knows" when you are using it. The warming plate doesn't turn on when using the stainless carafe. Seems to be a defect in the design. Maybe someday the manufacturer will figure it out.

As the responders state, the thermal carafe keeps the coffee hot for over 2 hours. I have poured a cup 4-5 hours after brew and it is perfect. You don't want an element that keeps it hot as that would ruin the coffee....Great product, highly recommended.

No-the carafe is a thermal carafe. Which I like. The coffee stays hot for hours in it-without getting burnt and that burnt flavor.
