Why does the plate beneath the carafe rust?
669417
My 4-cup Cuisinart has done the same thing. The coating peeled away little by little exposing the metal plate beneath. I am assuming it's because the factory has set a warming temperature on the plate too high and the thermal coating was not correctly mated. I'd much prefer a stainless warming plate rather than a thermal coated warming plate. Still brews a terrific coffee, but without that coating there is a concern about the warming plate's integrity now. Cuisinart should learn from all these concerns expressed.

Corrode is a better word. The coating on the plate has peeled off exposing the bare metal underneath. I don't really know why this happened.

YEP, mine is 5 years old and the thermal coating where the pot sits on the actual unit itself, does peel off after use. Its not really a hotplate because it does not stay on after the coffee is done brewing but it IS the element that is used to heat the water of the unit itself during brewing so it does get hot during the brewing cycle. It has never affected performance and to me, it is more of an eyesore but after the heavy use this machine has received in our house, it is understandable. If you do start to see metal showing through, toss the machine because you are risking bigger problems as the heating element is now exposed.

I soak mine frequently and have even run it through the dishwasher a few times. It has never rusted, but it has discolored slightly.

Mine never showed rust but I changed to the Rok coffee press for my espresso.

Yes! There is a problem. Seems like a new design and it is not right. Call Cuisinart and get another lid for carafe & a mesh holder, just inc ase there is a problem with that too. They have a 1-800#.It will not work right unless replaced!! somebody's idea of a new design doesn't work!!

Yes, you are correct. The plate is only a plastic sheet intended to protect the counter top from any accidental damage from the carafe. The best way to use the carafe is to pre-heat it using hot tap water before brewing the coffee. When the brewed coffee drips into the carafe, it does not cool it much (if any) since the carafe is already hot. The coffee will stay hot for a long time. I don't know how long because I generally make myself two cups in the morning and it never has time to cool off before I finish the second cup. The glass carafe with the hot plate will definitely keep the coffee warm longer but I have noticed thru the years that the hot plate seems to impart a "burnt" taste to the coffee if you let it stay on the heated plate very long. I like the double wall stainless steel carafe better as I don't think it affects the taste at all. I have a friend who swears he can taste a metal note when he uses a stainless steel carafe but I can't.

This has happened a few times for me. I have not pinpointed exact reason why. However, it seems to not occur if there is no water inside the carafe lid after washing it, carafe fully seated under basket, and lid closed all the way. Be sure nothing obstructs the small overflow opening on the lid also. Water should be able to run through it easily... as opposed to center hole.

The only thing I can suggest is what someone already did - take the underneath plate off, and use distilled water. Hope you did not put anything in the water..that will certain spoil the machine.

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.

Not really sure. I usually fill it with water so I have never noticed. Sorry couldn't be more helpful. I do like the carafe though... I ordered three of them to have on the table for company and for my kids when they have friends over.

It's because the grill is made by chrome. Some say that it doesn't rust but I believe the metal taste can get into the food with the time. If you notice the dehydrator made with stainless steel grill are more expensive.

i just swish it with water and wipe with a cloth but it is beginning to rust and black chunks are chipping off the inside bottom. I never drink the last cup out of the pot for fear of it being gritty. I assume the iron is not toxic but I am planning on getting a new one. I have owned this one for many years.

No rust issues, but mold has grown on the silicon rubber ring from time to time. I occasionally pull it out and run it through dishwasher. Anytime water is trapped, mold growth is possible. I consider it to be an annoyance more than a health hazard. No issues elsewhere with mold.

I have had mine for over a year with no problems. I clean the whole thing, including the carafe, by occasionally running white vinegar through it. I fill the reservoir with vinegar, put an empty coffee filter in the basket, and turn it on.

I haven't had rust on mine. I have had problems with some sort of black grease rolling out onto my fondant. Could have been a nice rolling pin if that hadn't happened.

i have mine for more than a year and have no complaints. if you want to prevent rust don't clean it in a dishwasher.... this is the only advice i can give

Don't know. The only problenn I can see is height. Measure the space under the basket the basket to the plate. Then check the height of the carafe to be sure there will be space for the coffee to drip into the carafe.

I don't know. There is no heating element associated with the carafe - only with heating the water to brew. I flip the switch off when it's done brewing.
