My basket always overflows, the water doesn,t empty fast enough

If it is a drip maker, only gravity drives the hot water thru the coffee grinds. If the coffee is ground too fine, it immediately packs up and doesn't let water flow thru it and the water flows around the coffee instead of thru it.
Try using a coarser grind, and if not you can use a lot smaller amount of coffee and water. A smaller amount of coffee is easier to diffuse thru than a large amount.

Another thing is to slow down the water speed entering the coffee basket. I found the best way to do that is to use water just above freezing and place that extra cold water in the reservoir. The cold water takes extra time to be heated up by the coffee maker so less water is released over the coffee grinds per minute.

If your coffee maker overflows a lot, that is a good indicator that the grind is too fine and/or your coffee filters are too flimsy and are plugging up the channels in your coffee basket and the coffee can't enter the flask, so it overflows.

But the easiest way to check out your coffee maker is to use extra cold water and just run half batches (5 cup) of coffee instead of 10 cup

What kind of paper filters are you using?I found that when I used store brand paper filters in my 12 cup Mr. Coffee I had a similar problem. They are thicker or something (less porous perhaps?) and the water doesn't pass through it fast enough.
When I went back to the more expensive Mr. Coffee filters the problem went away.

Good Luck

Hi,
Check the bottom needle...it is plugged...
Here is a tip that I wrote that will give you some things to try that will helpyou get your Keurig coffee brewer workingagain.

You should be able to pick up a replacement/new pot at your nearest Restaurant Supply store. Make sure you get a 64 oz./ 1/2 gallon pot.
Before plugging in your brewer, unscrew the sprayhead located just above where the filter basket sits and replace the basket, pour 3 pots of cold water through the opening on the top if the brewer is empty. This brewer has a reservoir that holds about 2 1/2 pots of water at brewing temperature when heated. Make sure you put an empty pot under the filter basket after pouring in the water. Water will flow from the brew basket when the reservoir has reached its capacity. Once water flows you can then plug in and energize your brewer and replace the sprayhead. It will take about 15 to 20 minutes for the brewer to reach brew temp, you will hear the heating stop. Put an empty filter and a dose of coffee (I recommend starting with a heaping measuring cup of drip ground coffee) into the filter basket, lightly shake it level, replace the basket and pour through 1 full pot of COLD water in the top. For best results pour the brewed coffee into a pre-heated thermal server if you plan on holding the coffee for more than 10 minutes or so.
Enjoy!

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 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.

These tanks can't actually be overfilled since all water poured in displaces the exact same amount of water coming out the spout. So, whatever amount of water you pour in, will be the same amount of water that flows to your pot minus the amount absorbed by the coffee grounds and filter.

Your problems sounds like an undersized (Non Bunn) filter, or clogged brew basket. To verify this, try pouring in only half the water for your brew cycle and wait for it to finish dripping, then pour in the rest. If no overflow has occurred, you simply have the wrong type of filter. If overflow begins again, you have a clogged brew basket, since no Bunn can flow too fast for the brew basket to keep up with it.

This is because Bunn filters are manufactured differently than generic store bought paper filters. They will flow faster, brew cleaner and stand up better than normal generic filters.
Remember, Bunn makes their OWN filters for good reason.
They made the first, best paper filters for drip coffee pots, and all others are just generic dioxin gas producing paper.

Sometimes this happens if you use filters that are too thick for the brewer. If you are using Bunn filters andthis keeps happening , up above your filter basket, there is a sprayhead. Turn that off, and look at it to see if it is plugged up.If there is no sprayhead, then that could cause your filter basket to overflow, as too much water will be coming into the basket too fast.

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 Bunn needs Bunn filters because they are thinner and let water through faster. The cheaper filters will overflow. Bunn's claim to fame is fast...this is just part of the fast process.
