I have a one cup at a time Keurig. I measure the water and pour in then Kcup coffee. I shut the covers and press brew. The coffee maker starts to heat the water but then will not pump the water through the Kcup. What's the problem? Thanks.

The Mr Coffee web site has the manual on the product page: http://www.mrcoffee.com/coffee-makers/mr.-coffee-optimal-brew-10-cup-thermal-coffeemaker-black/BVMC-PSTX91.html .

(You'll need Adobe Reader or a similar program to print the manual.)

The Clean light will come on when the Clean button is held. It won't go off until the cleaning cycle is complete; it's completely automated. You need 4 cups (20 oz.) of white vinegar or the Mr. Coffee Cleaner (diluted as directed on the package). Make sure to remove the water filter disk from the unit before cleaning. Pour the vinegar or cleaning solution into the reservoir into the reservoir. Put in a paper coffee filter or the permanent filter into the brew basket and slide it into place. Put the empty decanter in place. Now you should press the Clean button until the Clean light comes on. The unit should slow brew 3 cups of the cleaning solution and then pause for about 30 minutes while the Clean light remains on. It should then brew the remaining solution. After the cycle finishes, the Clean light should go off. Afterwards, you need to empty the decanter and rinse it with clean water. Fill the reservoir with fresh, clean water. Then replace the decanter. The cycle could take an hour.

I hope this helps.

Hi,

Here is a tip that I wrote that will give you some things to try that will helpyou get your Keurig coffee brewer workingagain.

Are you getting a message saying to "de-scale" it may need a good cleaning. That's usually the issue & the quickest fix. If the Keurig (or any other coffee maker) gets lime/calcium build up on the internal components it will ignore whatever has been programmed into it & just keep cutting off, keep making partial cups & just not working properly. Run some white vinegar thru it - fill the reservoir with a strong vinegar/water mix, remove any kcups/my kcup filters, also remove the reservoir carbon filter ( fyi - that's not going to eliminate any lime/calcium in your water - it's just to eliminate any bad tastes/odors) and "make" how ever many cups it takes to empty the reservoir.Depending on the build up - you may need to do this 2 or 3 times. Also run about 2 more reservoirs of just clear water to help rinse out the vinegar mix (otherwise your next cup of coffee will not be what you expected).
This may eliminate your problem & should be done every 2-3 mths. If that doesn't solve it - your Keurig may already be too far gone. Good Luck.

What model do you have? I'm guessing we are talking coffee maker, is it a Keurig? If you're getting a message saying to "de-scale" it need a good cleaning. That's usually the issue & the quickest fix. If the Keurig (or any other coffee maker) gets lime/calcium build up on the internal components it will ignore whatever has been programmed into it & just keep cutting off or keep making partial cups. Run some white vinegar thru it - fill the reservoir with a strong vinegar/water mix, remove any kcups/my kcup or filters, also remove the reservoir carbon filter ( fyi - that's not going to eliminate any lime/calcium in your water - it's just to eliminate any bad tastes/odors) and "make" how ever many cups it takes to empty the reservoir. Depending on the build up - you may need to do this 2 or 3 times. Also run about 2 more reservoirs of just clear water to help rinse out the vinegar mix (otherwise your next cup of coffee will not be what you expected).
This should eliminate your problem & should be done every 2-3 mths, regardless of whatever the model of coffee maker you have. Good Luck.

When is the last time it was cleaned? That's usually the issue & the quickest fix. If the Keurig gets lime/calcium build up on the internal components it will ignore whatever has been programmed into it & just keep cutting off or keep making partial cups. Run some white vinegar thru it - fill the reservoir with a strong vinegar/water mix, remove any kcups/my kcup, also remove the carbon filter ( fyi - that's not going to eliminate any lime/calcium in your water - it's just to eliminate any bad tastes/odors) and "make" how ever many cups it takes to empty the reservoir.

I know this sounds like a pain but it takes a while toget that silly light to stop. Decalcifying your MR. COFFEE® Coffeemaker Minerals(calcium/limestone) found in water will leave deposits in your coffeemaker andaffect its performance. It's recommended that you regularly remove these depositsusing MR. COFFEE® Cleaner or vinegar. MR. COFFEE® Cleaner is available at manyretail stores or by calling the MR. COFFEE® Consumer Service Department at 1-800-MR COFFEE(1-800-672-6333). 1. Follow packageinstructions to prepare one batch of MR. COFFEE® Cleaner. Pour the mixture into the water reservoir. Before decalcifying,remove the water filtration disk from the machine. NOTE: 4 cups or 20 fl. oz. of undiluted, white householdvinegar may be used as a substitute for the cleaner. 2. Place an emptyMR. COFFEE® 10-12 cup basket-style paper filter or MR. COFFEE® permanent filter into the filter basketand slide the brew basket in place. 3. Place theempty decanter back in the unit. 4. Press theCLEAN button until the CLEAN indicator light turns on (Figure 9). For your convenience the cleaning cycle isautomatic. The entire cycle will take 45-60 minutes to complete. During thecleaning your coffeemaker will: a. Slow brewapprox. 3 cups of cleaning solution. b. Pause for 30minutes (the CLEAN light will remain on to alert you that the process is active). c. After 30minutes, your coffeemaker will brew the remainder of the cleaning solution. d. When complete,the CLEAN light will turn off and your coffeemaker will turn off. 5. Discard the cleaning solution and rinse the decanterthoroughly with clean water. 6. Fill the water reservoir with clean, fresh water. 7. Place the empty decanter back on the coffeemaker. 8. Remove and discard the paper filter usedduring the cleaning cycle. If a Mr. Coffee® permanent filter was used during cleaning, remove it andrinse it thoroughly before replacing it in the filter basket. 9. Begin brewingand allow the full brew cycle to complete. 10. Repeat steps 5 through 9 one more time.

I clean my Mr Coffee by pouring a half water/white vinegar into the water holder andturn the coffee maker on andlet the vinegar do its thing. A refill with a little lemon juice in the water gets rid of any vinegary smell left behind.

Sorry to read about your problem, I hope this helps you out.
I would follow the cleaning list below, I an addition you may have a bad batch of k-cups
plus just run some hot water, with out a kcup in the holder.

1. Remove the K-Cup assembly
   To remove the assembly from the brewer, open the cover by lifting the handle. Grasp the top of the K-Cup Holder with one hand while pushing up on the bottom of the assembly from underneath with the other until it releases. The K-Cup Holder is dishwasher safe.
2. Clean the Funnel
   The Funnel can be removed from the K-Cup Holder by pulling on it until it snaps off. The Funnel is dishwasher safe. To replace it just snap it back onto the K-Cup Holder.
3. Clean the exit needle
   The exit needle is located on the inside bottom of the K-Cup Holder. If coffee grounds or cocoa mix gets clogged in the exit needle, it can be cleaned using a paper clip or similar tool. Remove the Funnel from the K-Cup Holder, insert the paper clip into the tube and move it around to loosen the clog and remove any debris. Please note, you cannot poke all the way through the needle as the opening of the needle is located on the side and not the top.
4. Install the K-Cup assembly into the brewer
   After cleaning, align the K-Cup Holder tabs with the opening placing the two front tabs on the bottom and the single tab on top and snap it into place by pushing down on the top rim.

You have to use a lot of vinegar as it evaporates....this is a coffee maker right and not a vacuum?
