When I turn the coffee maker on to brew a pot of coffee nothing happens. Water does not drip down through the coffee grinds. I have had this coffee maker for 1 month and was using it, and loved it. This week I turned it on to use it and within 10 minutes my whole house began smelling like burning plastic. Since that event the coffee maker stopped working. Did the pump that brings water to the coffee grinds burn out?

SOURCE: Won't brew a full pot.

well I hope this helps some, i was having a similar problem with my brewstation and decided to take it apart ( why not, it's already broken! ) this machine has seen a year of very heavy use and I could not bring myself to just throw it away. It would take forever to brew and I would have to turn it off and on several times to brew a full pot. I unplugged the machine, emptied out the water and turned it on it's back. Remove the 4 phillipshead screws and the two torx screws from the bottom ( if you dont have torx handy like me just gently pry the two halves apart till the screws pull through- after you have removed the phillips heads!) at this point the bottom will just come right off, no special tricks. You will now see a horseshoe shaped aluminum tube with orange silicone tubes at either ends of it, this is the heatime element. slide the small hose clamps back away from the element on the hoses and pull the hoses off both sides of the element end only, this will require a little elbow grease to do. Now carefully remove the two phillips screws securing the heating element to the maker BE OBSERVANT AS TO HOW THE WASHERS AND SPACERS ARE SECURED and remove them. To give yourself a little room for the element to come further out of the machine also remove the wiring clamp from the inside, it is a white half "c" plastic piece with 2 screws holding it, it is securing about 7 wires down with wire nuts on them. Once this is removed it will give you enough play to pull the heating element several inches away from the machine, do so. Now look inside the tubes of the element and you should see one side looks clear and clean and the other end is probably going to be clogged solid with tan colored gunk, the water could not pass through!. I took a piece of metal coat hangar (all i had around at the time) and bent it to the conture of the element and used it to **** out the element, uncloging it. this takes a little time because the buildup is very hard to break up. Once that is done carefully wash out the element getting all the build up that was broken up out, CLEAN IT GOOD!. The next step is to dry the exterior and make sure all the wiring is dry, try not to wet the wires at the wiring nuts or it may short out. Now re assemble the machine, run cleaner through and enjoy a cup of coffee !!

SOURCE: Cuisinart Grind and Brew will not emply all the water

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.

When we put water in to brew a pot of coffee the water overflows in the basket and runs over. Why does it do this when the proper amount of water is added?

I assume this is a drip coffeemaker using a drip filter. If so, does it grind the grounds or do you add them? Are you using a paper filter or the gold one? Try a coarser grind and make half a pot. Then check level of brewed grounds. Never use a gold and paper filter together.

Drips both inside and outside pot. I've ckg for clogs. Nothing clogging

Based on what you wrote, it sounds like your ground coffee basket is overflowing. This happens with my coffee maker if I grind the coffee too fine, or the coffee is very fresh and is off gassing nitrogen.

I shake the basket back and forth rapidly, and often stop the drip to allow the grounds to soak up water for a minute before allowing to go bak to brewing.

I hope I guessed your problem, if so, grind your coffee a bit more course or do as I do, leave ti the way i like it and allow the grounds to soak up some water before continuing with a full brew cycle.

Have "new" reburbished machine suddenly lt it

might be the tube where it sucks the water up to brew in the first place, easiest way without tearing her apart is to brew a pot with CLR(Calcium,Lime Rust Remover), look up the water to CLR ratio and clean well when finished (run a few just waters after) Hopefully you'll be getting your Java fix in no time

Coffee is in water is in nothing happens

You may not have enough water in the tank.
Follow these steps

1. With the coffee pot unplugged, fill your resevoir/tank until water begins pouring out of your sprayhead and brew basket.
2. Wait for the water to finish dripping then plug in your Bunn.
3. Let your Bunn warm up for at least 8 minutes.
4. Run a test cycle with clean water, remembering to use the water pitcher provided for this purpose, while leaving your empty pot on the burner beneath the brew basket.
5. If your cycle completed, and your coffee pot is filled to the desired level you are ready to make coffee.

Remember that these Bunn models have no water filter2_bing.gif installed, so, the cleaner the water the better tasting the coffee.

Our coffee maker is only brewing half of the amount of coffee it should. Half way through the brewing, it shuts off. We've cleaned it with vinegar, but it still happens intermittently. It's actually...

Run a 1/2 pot of vinegar through it 2-3 times (I reuse it) and then run water 1-2 times to get the vinegar smell out. This cleans the mineral deposits from your water that are clogging it.

My Cuisinart 10 cup Grind & Brew does not finish the brew cycle. After brewing 2 cups of coffee, it beeps 5 times as if the brew cycle has ended. Then it continues to drip very very slowly. It's only...

you need to run a few pots of straight white vinegar through the machine to clean out the lime build up in the tubes. the first time you do it, after it starts to pump the water, shut it off for a few hours and let the vinegar sit in the tubes. after doing this run a few pots of cold water through before making coffee.

My grind and brew turns itself off in the middle of brew cycle

Coffee overflowing onto the counter is a common complaint found in response to many automatic drip coffee makers. The following are potential solutions that can be used to rule out "operator error" vs. a defect or malfunction:

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. If self-grinding your coffee beans, ensure you are using the correct grind setting for an automatic drip coffee maker. (See instruction manual for coffee maker and/or grinder.)
3. Do not overfill tank with water. Use the marks on the side of the reservoir as a guide rather than those defined by another measuring method. This is because a "cup" in a coffee carafe is defined as 6 oz, not 8 oz, and in some cases as little as 5 oz as a cup. As such, a 12-cup machine actually produces closer to 9 standard 8 oz cups. (See your owner's manual.)
4. Make certain the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.
6. Only use the correct permanent or paper filter (see manual).
7. Verify that the Pause 'n Serve button isn't sticking. If it is activated too long the brew will escape over the top of the cone/basket. This may be more apt to happen if the alignment of the carafe and the basket is incorrect.
8. It is extremely important to clean your machine with vinegar or as instructed by your owner's manual at least three times per year, more if your water supply is hard (prone to leaving water rings). A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew a pot of coffee, to produce "off" tasting coffee, or to clog and overrun the filter basket.
9. Ensure that the coffee machine is sitting level on the counter.

Can I adjust the water flow for finely ground coffee?

You probably have coffee ground for a drip coffee pot, not an automatic drip coffee maker. With a drip coffee pot, you put the coffee in and add the hot water on top of that. You might want to try a coffee press. They are fantastic for the finer grinds of coffee. Some Mexican coffees are ground almost as fine as flour and a press works great. You can get a press for about $12 & up.

Cuisinart grind and brew

This happens when the machine needs cleaned. Fill coffee maker with white vineger instead of water. Turn grind off, make sure empty pot is in place. Brew a pot of hot vineger. Repeat. Brew a pot of hot water. Repeat. This process removes mineral buildups inside machine. If you have access to filtered water, start using that to brew your coffee. I do and probably do this process 1 per 6 weeks.

Keeps flashing 12:00

I just kept plugging and unplugging the coffee pot. Eventually, the clock stopped blinking, the buttons worked, and all was well.
