NOT SO GREAT COFFEE GROUNDS!

I looked up your problem and found the same one was answered previously on fixya. I have copied and pasted the previous answer here for you. Good luck and I hope you have a great day!
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.

2 cups of coffee grounds for 36 cups of water.

Your manual is free to download here. Page 4 lists combinations of coffee grounds and water for coffee.
I hope this helps & good luck! Please rate my reply. Thank you..

20 cups of coffee needs 2 cups of coffee grounds
30 cups of coffee needs 2 1/2 cups if grounds
40 cups of coffee needs 3 cups of grounds
45 cups of coffee needs 3 1/2 cups of grounds

1 cup brewed coffee = 5 fluid ounces
* use standard measuring cups

that would depend on the coffee, and how strong you like it.

as well as how large your standard cups are.

I use 1/4 cup of folgers classic blend for 4 'normal' cups of coffee. I also use an oversized camping mug - so 4 normal cups fills two of the mugs. - - - you may want to try 1 1/8 cup of coffee grounds in the filter if making a full pot.

Hi,
!/4 cup of coffee for every 8 cups of water or almost a full cup of coffe for your 30 cup pot...

I have the answer because it is happening to me now. Moreso with the Timmothy's brand K cups. I did a little forensics on a good brew, and then on two slow with grounds in the final brewed coffee.
The inner filter is placed in the k cup and it is not glued to the top rim. The bag then just sits on the bottom of the k cup as it is passed with the hot pressurized water.
The good cups are glued to the top rim and there is no problem.
To investigate....remove the foil top carefully after the cup cools. Rinse out the grounds, and the filter bag should still be glued to the rim. if you've got a dribbler and one that passes the grounds into the cup...you will find the filter bag had fallen loose from the rim. Manufacturer defect...You bet!!!
I had 8 from a box of Timmothys 25 count pass grounds. Green mountain coffee may once in a while pass grounds, but very rare and maybe three times in the 4,000 k-cups we've used.

We use 2 1/4 cups for a full 36 cups. A fraction under 1 1/2 cups is good for 22 cups.

You might want to try decalcifying your machine. See my comment here:
