Basket with coffee and filter overflows. Why?

Steven, I think it`s not the filter or the coffee just that more water is flowing into the basket then it can process. I would try lesser quantity of water first to see if it overflows. Try first with filter only and then with coffee. And before you do all that, your machine should be under warranty and may be returnable to the store. Do that and save the trouble of fixing it.

Dunkin Donuts decaf coffee clogs the filter as the water fills the basket causing the basket to overflow. The coffee is ground too fine. Swtich brands or use a second filter to cover the coffee grounds to keep them from floating and clogging the filter.

Make sure your sprayhead is the proper one (5 hole) and in good shape. Also make sure that the hole on your filter basket has not been partially closed. This can happen if you set it on the hot warmer. As a last resort, you can slightly enlarge the hole in your filter basket.

Some people also try adding fresh grounds to brewed grounds, resulting in an overflow. A restricter valve can be used, but a better solution is to simply pour in half the water at a time. This is what people who buy non Bunn filters do to stop overfills.

The two most common reasons for overflow have to do with the caraffe lid and the filter basket - they key to smooth flow with this coffee maker is making sure the filter basket and caraffe lid are making the proper contact with each other so that the center knob on the caraffe lid pushes slightly up on the filter basket spring. Make sure the caraffe lid is completely closed. Make sure the filter basket is pushed all the way down. Make sure you are not using the gold tone filter and a paper filter at the same time. For some reason, I get better results when the handle of the caraffe is resting against the right side wall. If everything is in place, I would suspect a problem with either the filter basket being clogged or some problem with the caraffe lid - call Cuisinart as they should be able to order these parts for you.

Do you grind your beans at home before brewing or is it ground from the store. If you grind just before brewing check her grind and compare it with yours.
Also check to see if she levels the coffee in the basket. Usually when a pot overflows it is because of the grind or the way the coffee sits in the basket.

MORE COFFEE

The grind on your coffee is too fine, and if not there is too much coffee in the basket, hence the overflow.
