It want give me a whole cup i have to keep opening and closing the top and it start to brewing then it will stop

A. Prepare
Step 1: Make sure you have 48 ounces of white vinegar on hand. You will also need an empty sink and a ceramic mug (Do not use a paper cup.)
Step 2: Empty the water in the water reservoir
B. Fill and Clean
Step 1: Pour the vinegar into the water reservoir and fill it to the top edge of the clear viewing area.
Step 2: Place a ceramic cup in the drip tray and run a brew cycle. DO NOT USE A K-CUP...just press the large cup button. Pour the contents of the cup into the sink.
Step 3: Repeat the brew process until the water reservoir is empty, pouring the contents of the cup into the sink after each cycle. Remember to open and close the lid between each cycle.
Step 4: Now fill the reservoir with fresh water and let the brewer stand for 4-hours while it is still on.
C. Rinse
Step 1: Ensure the water reservoir is filled with fresh water.

Step 2: Place a ceramic cup on the drip tray and run a regular brew cycle. Once again, DO NOT USE A K-CUP...Pour the contents of the cup into the sink.

Step 3: Repeat the brew process until the water reservoir is empty.

Step 4: You may need to perform additional brew cycles if you notice any residual taste.

my kuerig has water come through the k cup when I close the top without pushing brew cup size and if it does let me make a selection it brews 1/4 of cup I have descaled it 4 times locked in the water reservoir cleaned the needles turned it on and off any other suggestions to try would be greatly appreciated thank you

I had this problem too.
I just pressed the small brew button; it pulled some water from the reservoir and heated it but nothing came out. Then I opened and closed the top cop thing and both the cup sizes were flashing and it worked like normal again.

Hi,

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

Keurig Coffee Brewer not making a full cup of Coffee

The next time you go to brew a cup, open the lid to the water well and locate the little clear rubber spout that sticks out of the side of the machine toward the top. When you brew the cup watch the spout to see if water is coming out of it into the water well. If it is you can just put your finger over the hole and the machine should brew the whole cup.

I usually only have to do this once every time the problem starts happening, but it is clearly not a permanent solution. I assume the problem is with a valve inside the machine or something, and to fix it permanently you should probably get the unit serviced or exchanged under manufacturers warranty.

Open the brew mechanism. Opening the brew
mechanism will initiate the heating of the water and the
HEATING light will flash.
2 Place a clean cup on the cup stand, adjusting the height of the
stand up or down so that the rim of the cup is close to the
brew mechanism.
• To adjust the cup stand, insert your finger in the center
of the stand, lift and turn.
• To avoid spilling over, please choose the right sized cup for
the drink you are making.
3 Position your choice of T-DISC on the T-DISC holder, label facing
down. Firmly close the brew mechanism by pressing the clamp
down until it shuts. The HEATING light may flash again as the
machine heats the water to the required temperature for
your drink.
4 When the AUTO light illuminates, press and release the start/stop
button. Brewing will start automatically. There may be a short pause
during brewing; this is normal and is designed to draw out the full flavor
of your drink. The AUTO light flashes throughout the brew cycle. When
the machine has finished brewing, the indicator light will move from
AUTO to MANUAL and then, after a delay of 30 seconds, to HEATING.
5 Open the brew mechanism, remove the T-DISC and discard.
Your drink is now ready to be enjoyed.
You can prepare the next beverage right away by repeating
steps 2 - 5.

After many months, I solved the problem of the red light staying on the Tassimo Coffee Maker. Use these easy steps.
1. Fill a 2 cup measuring cup with hot water.
2. Mix in descaler.
3. Pour in the empty water tank.
4. Put the yellow cleaning disk in the chamber and close chamber. Put the two cup measuring cup under the spout.
5. Push and hold the brew button for about 3 seconds (until the red and green light flash.
6. Now don't touch the machine. It will do it's thing for about 20 minutes. (Don't be impatient and start to push buttons, just leave it)
7. When it finishes it's cycle. The red light will turn off. Then clean the water tank and put fresh water and run clean water through the brewing cycle 4 times. Your machine is now ready for use.

I use distilled white vinegar, but you can use specialized coffee cleaners with this model:

Descaling
Descaling 11
Descale your Tassimo machine every three months to keep it
operating at full potential.
1 Descaling products are widely available from stores selling coffeemakers and espresso
machines. Only use a product intended for descaling. Mix the descaling product
directly in the water container, following the instructions provided on the descaling
packaging. Replace the water container on the machine.
2 Place a large cup or mug on the cup stand, insert the cleaning disc, bar code down,
and close the brew mechanism. When the AUTO light illuminates, press and release
the start/stop button. The brew cycle will fill the machine with descaling solution. Empty
the cup and let the machine stand for 15 minutes.
3 Open the brew mechanism and close it again, leaving the cleaning disc in place.
When the AUTO light illuminates, press and release the start/stop button. When the
machine stops running, empty the cup, and let the machine stand for 15 minutes.
Repeat this step two more times for maximum descaling effectiveness. Discard the
remaining descaling agent from the water container, rinse it thoroughly and refill
with fresh, cold water.
4 Open and close the brew mechanism again, leaving the cleaning disc in place.
When the AUTO light illuminates, press and hold the start/stop button to flush water
through the machine. The MANUAL light will flash. When the cup is full, release the
start/stop button, empty the cup, and replace it on the cup stand.
5 Repeat step 4, flushing clean water through the machine in the same manner and
emptying the cup as it fills. To ensure that all the descaling solution is completely rinsed
away, flush two full water containers through the machine before using it again.

Having the same problem. It's a thermostat issue. The product seems to have three. Trying to figure out which one is causing the problem.

We have had this problem intermittently but we had a bigger problem that I solved yesterday. Our LCD display was not displaying properly - words were missing so we just had to guess when it was ready to brew. I called Keurig and they offered a new one for $100 since it was out of warranty. They did ask me if I had descaled the machine and, I'm embarassed to say, I had never done that. Well I descaled the machine and viola! - my LCD display completely came back just like new! Here's hoping the intermittent brewing problem is resolved as well! If you haven't descaled the machine recently, I would strongly suggest giving that a try for any problems you might be having. Of course, to descale, the machine has to at least be able to brew in order to get the vinegar through the machine...
