How do you reset the low water red light on my Tassimo 4511 (Bosch) Coffeemaker...it's blinking and there is plenty of water in it? I can't even use the descaling feature....it won't do anything?

Are you refilling the tank during this process? You need to let in run dry, and then the buttons flash. Then, refill the tank with clean water, and let the tank run dry again.

Solution: Just refill the water tank with water (no descaling solution) all the way to the "Max Line". Then run the full descaling program again --takes approx. 20 minutes. After the program runs completely you will get the yellow "standby" light on and the red "descaling" light will be off.

Next time you descale, be sure and fill your water tank to the "Max Line" before running the descaling program.
Hint: An incomplete cycle (not full tank) is what makes the red light stay on. In other words, it's staying red to tell you to run a full cycle (beginning with the water tank filled to the "Max Line"). Hope this tip is helpful!

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.

You should be able to get descalers from your local supermarket.

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.
