Lights keep flashing on my tassimo machine

If all the indicator lights are flashing after you've initialized your machine, reset it by turning it off and then on. If there's no disk in the brewing mechanism, all the indicator lights will flash.Sep 5, 2020

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.

According to the manual, when both lights 7d and 7e are on at the same time, you need to contact Tassimo.

In order to keep your Tassimo machine operational at full order, it is important to descale it every three months. Descaling products are widely available from stores that sell coffeemakers and espresso machines. Be sure that the product you buy to descale your Tassimo machine is intended for this specific use only. Mix the descaling product directly in the water container, following the instructions provided on the descaling packaging. Then replace the water container on the machine. Place a large cup or mug on the cup stand, insert the cleaning disc, bar code down and close the brew mechanism. As soon as the AUTO light illuminates, press and release the start/stop button. This will fill the brew cycle with descaling solution. Empty the cup and let the machine stand for 15 minutes. Then open the brew mechanism and close it again, leaving the cleaning disc in place. Repeat this step two more times for maximum descaling effectiveness.

Discard the remaining descaling agent from the water container, rinse it well and refill with fresh, cold water. Clean the machine by flushing water through it in the same manner and emptying the cup as it fills. Make sure that all the descaling solution has been completely rinsed away, and then flush two full water containers through the machine before using it again. Remove the cleaning disc, rinse and refill the water container and your Tassimo machine is ready to use. Also, before you descale your Tassimo machine, always unplug it. Also, never immerse the appliance in water and nor should you use abrasive cleaning products or scouring materials on any part of your Tassimo machine. This method works for most espresso machines, including some of these popular models: the DeLonghi Magnifica EAM3200S, DeLonghi Magnifica ESAM4200S, DeLonghi Perfecta ESAM5400, Gaggia 74507BCN Classic, Krups EA8080 Espresseria Automatic, DeLonghi PrimaDonna ESAM6600, the BC0255 DeLonghi coffee machine and the Krups Nespresso CititZ XN 7006.

My Tassimo was doing the same thing. Defective tank sensor, I taped a small magnet on the back just above the power switch next to the water tank to trick the machine into thinking there is water in the tank. Just make sure there is water in the tank, as the sensor is now fooled on.

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.
