First of all it depends on the hardness of the water. Vinegar doesn't really work in the heavy lime belt area of the midwest. It is better if you use lime away. It is an ecolab product that is great at lime removal. Use one cup per pot. Then rinse two pots worth if this is the kind of machine that uses the same water that is put in during each brew cycle. Some brewers have a reservoir. Bunnomatic is an example of that kind of brewer. If you use lime away in that kind of brewer you need to run about thirty pots to remove all the lime scale remover from the brewer. Slow brewing can also be caused by over softened water. I drove from Indy to Iowa after installing a brewer and then a day later the store put in a softener and over softened the water causing the coffee filter to clog up with sodium. Also check the sprayer disc or head where the water comes out. Over time coffee "paste" will build up around the outlet and if you don't wipe it clean or "smear" the coffee grounds around the outlet that will slow down the brewing cycle. I have thirty years as a brewer technician and it is usually one of the things I have covered, providing that the heat element isn't defective.

Use a mix of 50% laundry bleach and 50% water.
Half fill the tank and let it soak for several hours.
Rinse tank and refill with fresh water only.
NEVER RUN BLEACH THROUGH THE MACHINE.

Hello sandra_strat,
There are two possible issues, but easy to do. When decalcifying your unit the solution should be 2 parts water and 1 part vinegar. So if you have a 12 cup maker it would be 8 cups water and 4 cups vinegar. Complete the process with a pot or two of fresh water to rinse. Second, there may be a water filter stick that is removable. Open the lid and look for it in one of the corners, pull it out and remove the carbon filter there. (You can get a new on Amazon). Then replace the stick.
I hope this is a help for you. If it is please leave positive feedback for me. Thanks! NormanZ

I'm having the same problem with my machine. I rang the Tassimo careline and they told me to descale the machine but, so far, this has only made matters worse. I'm now going to take it back to where I got it from because it's still within its warranty.

just posted this solution to another problem. there is something on the glass bar code reader up where you insert the t-disc - or the water vessel is not properly seated in the base of the coffee maker.
Check both.
