What Cleaning Method is Best for Descaling Bosch Tassimo Coffee Machine?

Tassimo T12 coffee machine

Actually, there are 2 cleaning methods. One is a quick and easy cleaning method and the second method is a bit longer which takes at least 20 to 30 minutes to get the best results.

I will explain both the methods in this guide. Don’t worry; both cleaning methods are really easy to follow at your home.

Cleaning and Descaling Method 1: (Easiest and Takes 2-3 Minutes)

1. First, make sure that the water tank at the back of your Tassimo machine should be filled at least 50% or more.

2. Now take out the yellowish round cleaning T disk from your machine. It is usually located at the lower back of your machine just below the water tank.

This location could change depending on the type of your coffee machine and the time when you purchased it.

3. After this, open the front lid (brew head) of your machine and place this yellowish cleaning disk inside the lid and close it properly.

The machine automatically understands that the disk you placed is a cleaning disk and not a coffee disk due to its bar code on the back side.

4. Once you do this, just take a coffee mug or a glass and place it under the coffee outlet.

5. Now, it is time to press the big start button on the right side of the mug. Press the button and now wait for next 2-3 minutes to allow the machine to do the cleaning and descaling on its own.

6. Once the process is started, you will see the water coming out of the outlet. It will be yellowish or darker in color which indicates that the machine has already done the cleaning of its internal parts.

7. When this cleaning process is finished, you will see water steam coming out of the outlet and the whole descaling procedure is completed.

You will also see the “Ready” light flashing which means your machine is ready to brew a clean coffee for you.

8. In the end, throw away the dirty water stored inside the coffee mug or a cup. Take out the cleaning disk from the lid and place it in the back of your machine where it was originally located.

9. That’s it guys. This is the easiest and fastest cleaning method which you can follow at any time of the day.

I recommend you to do it at least once or twice a week to keep your machine clean internally. It is important to brew the cleanest and bacteria free coffee for yourself and for others too.

To understand the whole process more precisely, I suggest you watch the following video instructions.

This cleaning process is pretty comprehensive in nature and it takes into account the cleaning of almost all the parts of your Tassimo machine.

This method is also called as a complete descaling of your coffee brewer.

I highly recommend this method to every Bosch Tassimo machine owner.

You need to follow this procedure at least once or twice every 2-3 months depending upon your usage and coffee making frequency.

This is an advanced version of method 1 and can take up to 20 to 30 minutes to finish the entire cleaning process.

All the removable parts of the Tassimo coffee machine are dishwasher safe which means you can wash them with the help of your household dishwasher.

The only exceptions to this are the water tank and filter cartridge holder. You will need to rinse and clean them with your hands and only with the clean water.

This complete descaling method is applicable to almost all the newer and older versions of Tassimo coffee machines like T12, T32, T45, and T65, etc.

The actual process is as mentioned below.

What You Will Need:

1. A Glass Measuring Cup

2. Microfiber Cloth

3. Bosch Tassimo Descaling Tablets

Cleaning Procedure:

1. The first thing you will need to do is take out the water tank of your Tassimo machine located in the back.

Fill up the water tank with 17 ounces (about 500 ml) or more amount of clean water with the help of a glass measuring cup.

2. Now its time to take out 2 Bosch descaling tablets from the pack and add them inside the water tank.

The main advantage or the benefit of using Tassimo descaling tablets is their ability to eliminate limescale residue and prevent forming of calcium deposits inside your coffee machine.

This also helps to improve or enhance the overall life span and performance of your machine. Only 2 tablets per treatment are sufficient.

3. After you add the descaling tablets to the water, you will have to take out the yellowish service T disc from the back of your coffee machine.

It is usually located at the lowest back side. Place it inside the front brew head of the machine and snap down the lid properly.

4. You will also need to place the water tank at the back in its original position before you start the cleaning process.

5. Now, take out the coffee cup stand placed under the main coffee outlet. And place the empty measuring glass cup in its place.

6. The step I am about to mention now is the most important one and many people tend to ignore it when cleaning this machine. So please don’t forget this step.

You will need to press the main “Start” button for at least 5 seconds in order to initiate the complete cleaning and descaling process of Tassimo machine in this method.

7. Once you press the start button for at least 5 seconds, then the entire cleaning process will take place in about 20 to 30 minutes.

When you see the Orange light is ON, that’s the time to know that the machine has done its automated cleaning procedure.

8. Now, taker out the glass measuring cup which is now full of dirty and unclean water that came out from the main outlet.

Throw that water in the kitchen sink or just give it to your house plants.

9. After this process is over, you can take out the water tank, rinse it properly and clean it again with the water.

Fill up the water tank again with the clean water and place it back in its original position.

10. You might be thinking of removing the service disk now. But don’t do it yet. You will still need it.

Open the front lid or brew head again and just close it again while the cleaning T disk is inside.

11. Now, we have to repeat the first cleaning method here to clean the entire machine thoroughly and properly.

This step is also important to make sure all the internal calcium deposits and other dirt is eliminated completely.

12. Place the empty measuring glass cup on the cup stand again.

Press the start button again for just 1 or 2 seconds and not for 5 seconds this time. The second cleaning process will begin now.

13. Once this short cleaning process is finished, take out the filled measuring cup and throw the unclean water away.

You will need to repeat this simple cleaning process for 4 more times.

14. When this entire second phase cleaning is done, you can open the front lid and take out the cleaning service disc and put it in the back side where it was originally located.

15. Now for the final cleaning phase, you will just need to wash the T Disc Holder or Filter Cartridge Holder and piercer outlet.

These parts are removable and easily washable with the clean water.

16. As mentioned earlier, you can not wash these parts in the dishwasher as it can cause material damage.

So, it is advised to wash and clean these parts along with the water tank with your hands under the tap water.

17. Once you clean these parts properly with the water, install them appropriately at their original positions.

18. In the meantime, you can use a quality microfiber cloth to clean the barcode reader situated inside the brew head or front lid.

This is important in order to maintain the coffee maker’s ability to read the bar code properly.

19. And that’s it, guys. This is how you can thoroughly clean and properly descale your Tassimo coffee machine in under 20-30 minutes.

To get a clear idea of this second cleaning process, I highly recommend you to watch the following video instructions from official Bosch Tassimo manufacturer.

Can You Clean Tassimo Machine without a Cleaning Disc?

I researched a lot about the possibility of cleaning all Tassimo single serve coffee makers without using T disc.

According to this source, it is not actually essential to use a cleaning disc.

This source says that you can simply use a diluted white vinegar solution to clean your machine. You don’t need a T-disc for this purpose.

But when I researched about the Tassimo company manual, then I found out that using vinegar solution is highly prohibited by the company itself.

If you use vinegar solution to clean your machine, then it will void your machine warranty.

Plus, any type of vinegar or other acetic acid-based descaler solutions can harm your coffee machine and could be responsible for changing the taste of your coffee.

So, I will not recommend cleaning your machine with vinegar solution.

It is always best to use a cleaning T disc provided by the company itself to clean your machine.

If your disc is damaged or even if you don’t have it right now, you can simply buy it online.

It is very affordable and the most reliable solution to keep your machine safe and working for a long period of time.

Plus, using this type of acetic acid based descaling solution is not safe for your machine.

Because it could potentially damage some machine parts and the worst thing is it could entirely change the taste of your coffee.

At least, I would not take any risk of using vinegar solution to clean my machine. What is your opinion? Let me know.

In my opinion, the descaling tablets solution is much better and safer option than using vinegar itself.

Instead of white vinegar, the best thing to use is the official descaling tablets offered by the company itself.

These descaling tablets keep your machine in perfect working condition for a longer period. This is done by removal of calcium deposits and limescale residue of your coffee machine.
