Brew basket porblems

I believe your problem is the filter basket holder is not seated correctly or the carafe is not completely inserted in the unit to push the brew pause lever up. The brew pause feature which stops the coffee from going into the carafe when you want a cup of coffee before the brew cycle is done. When you remove the carafe a spring lever stops the coffee from dripping into the carafe. When the carafe is inserted it must push the spring lever up to allow the coffee to flow into the carafe. If it is not the coffee will overflow and make a mess. The filter basket holder should be firmly seated in the unit so it will not have any play in it. Cuisinart recommends using a vinegar and water mixture but BrewRite Cleaner (Sodium Carbonate) available in the coffee section at Wallmart, Kamart and Target is fantastic. You can clean your carafe with BrewRite Cleaner and hot water by letting it soak a few minutes and rinsing. I will also clean your filter basket holder by soaking it as well and all your coffee residue will be gone with no scrubbing.

Make sure you are not using a paper filter and a gold tone filter at the same time.

Make sure the carafe lid is down all the way and that the center knob of the carafe lid is making contact with the spring at the bottom of the filter basket.

If the above conditions have been met, then decalcify your coffeemaker by running 1/3 carafe worth of vinegar and 2/3 carafe worth of water through your coffeemaker - use the self-clean button to do this - will take about 35 minutes.

The two most common reasons for overflow or underflow have to do with the carafe lid and the filter basket - they key to smooth flow with this coffee maker is making sure the filter basket and carafe lid are making the proper contact with each other so that the center knob on the carafe lid pushes slightly up on the filter basket spring. Make sure the carafe 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 carafe 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 carafe lid - call Cuisinart as they should be able to order these parts for you.

If water is leaking from the very bottom of the machine, your unit is broke and you need to call Cuisinart. If it is just overflowing the caraffe/basket:

Your coffee maker likely has the option where you can remove the carafe while it is brewing so that you can serve yourself in the middle of the brew. When you pull out the carafe in the middle of the brew, a small lever closes off the drip at the end of the basket (to keep the coffee from flowing onto the empty space where the carafe was on onto the burner).

Then when you replace the carafe, the lip of the carafe pushes against that lever and re-opens the valve so that the brew can now drip into the replaced carafe. Simple.

In your case, it appears that when you place the carafe onto the burner plate, it is not engaging that lever and opening up the valve; hence the valve stays closed and the brew fills over the basket and makes a mess, right?

So do this, pull out the carafe and look up where the pointed end of the basket drips into the carafe. You should see a lever, or plate that the carafe top lip hits when the carafe is placed into the burner plate. Once you find that lever, or plate, give it a push (like the carafe would) and see if it moves. if it does not, then that's your problem. It is stuck closed and won't allow the brew to exit the basket into the carafe. Clean it thoroughly if it is stuck and then see if works.

No one has just the individual part, but you can get the whole brew basket with the part included on Cuinart's website, or by calling them.

Replace the filter basket - they can be had for around $6.00 plus shipping - you can even get them directly from Cuisinart.

I just called Cuisinart and they will send me another brew basket for my DCC-100 (it has a Brew Pause valve also) for $9.14 (part + S&H). Did you try to contact Cuisinart?
