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've had mine now for a couple of months and love it. I would be surprised if it does rust, though I haven't had a lot of time to really answer definitively. It cleans wonderfully though and even the baked on drips slide right off. Thanks

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'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.

I bought it from costco few months ago and it does rust. Worst part the rust now is on the plates & cups. Not a good buy. Looking for new one.

Sell the carafe on eBay and put the rest in the garbage. Mine did the same after 3 months.

If you still have the receipt, just return it for a full refund. My coffee pot rusted on the bottom & Penneys replaced it. The second one also rusted, but this time the warranty had expired so now I'm stuck with an expensive pot that I can't use. It is a piece of junk! If you can get a refund, do it.

I'm a retired plumber and have seen this happen on stainless sinks because people use metal pads on the sink to clean it,the metal embeds itself in the stainless causing the rust, also low nickle content on cheaper sinks will cause the rusting, hope this helps.

The part inside of the percolator gets dark rust spots around the place where the percolator fits in the hole. So I stopped using it. I waited too long to return, because I didn't use it right away. The rust got so bad I just stop using it.

It is metal. The coffee stays hot for some time because the pot is insulated. I would be afraid the a hot plate would burn the grounds since they are compressed on the bottom of the pot.

Mine has been on for over a year and hasn't rusted. It is zing dipped. However i do remove the guide plate after each use. and I do remove the receiver once I have parked the trailer or boat.

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 have no clue. I do know that ours has 3 rust spots on it, after less than a year. Very disappointing quality, especially for the outrageous price I paid.

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

The surface of the heated plate on our unit appears to have started discoloring. I'm not sure it's rust;could be lime build-up. We've only had the unit about six months, so this is a little unexpected. The unit works great in all other respects.

No, I didn't experience any rust and I bought about 1 and half years ago. It's one of the best glass electric kettles I have used. The best thing is I can put my hand inside to scrub and clean the residue built up on the bottom of the kettle. So the inside surface still looks pretty good and shiny. I wish the spout can be better designed to avoid spills when pouring the hot water. Now I make sure I lift the hot lid up till it's perpendicular and pour carefully to avoid spillage. Good luck.

I am using Dawn dishwashing liquid, a dishwashing cloth and a long handled spoon to rub the cloth around the inside of the carafe. Works.
