Tassimo: Problem-Solving

⚠️ Before you start, here is a list of the items you might need to troubleshoot your Tassimo coffee machine: descalers, condensers, thermal fuses or spare water tanks.

The Tassimo brand is one of the most popular and widespread capsule coffee maker systems, so it was only a matter of time before we made room on our pages for the problem solving of the Tassimo coffee maker.

Like all machines, Tassimo machines suffer over time from breakdowns or blockages that we do not know how to solve. Many times it is not a question of the Tassimo coffee machine breaking down, but merely a lack of knowledge on our part.

Such phrases like “I have problems with my Tassimo coffee machine” are often more the product of ignorance than symptoms of a real breakdown. Be that as it may, here we go with a complete troubleshooting guide to Tassimo coffee machines.

We collect the most frequent questions and concerns of our Tassimo readers, and we answer them in the most concise way possible.

My Tassimo coffee machine doesn’t work

We’ve called this mega article Tassimo Solutions and Problems, but we’re going to start with a query that often comes up in many other brands’ coffee machines.

If your Tassimo coffee maker does not turn on, one of the most common causes may be the capacitors or the electric plate. You can find more information at this link.

My Tassimo coffee maker does not heat

When your Tassimo coffee maker does not heat the water, two measures, in particular, must be taken:

  • First, practice a complete decalcification. If you have not decalcified your Tassimo coffee machine for too long, sediment and impurities may have accumulated to such an extent that the water cannot circulate correctly to/from the boiler (Thermoblock, in this case).
  • As with almost all domestic capsule coffee machines, Tassimo coffee machines use the Thermoblock system to heat the water. It is not that common, but it can happen that the entire thermoblock has broken down, and you are forced to replace it.

My Tassimo coffee machine loses water

There are times when water may appear underneath your Tassimo coffee maker. These are usually small losses (nothing too big) but very cumbersome. There are often two causes for this problem, which are different from each other:

  • The drip tray is full. It may seem obvious, but sometimes we forget to empty it, and the remains of the coffees overflow. Check it out, just in case.
  • The water tank or capsule punch unit (where you put your T-Discs) is not adjusted correctly. These are pieces that fit millimetre by millimetre, so if we’re not careful, we can have them appear in the right situation but not adjusted. Then the water won’t be able to flow through them properly and will end up coming out where it shouldn’t (usually under the coffee maker).

The red light is On in my Tassimo coffee maker

The indicator lights on Tassimo coffee machines are one of the workhorses of all users. There is nothing that bothers us more than a little light blinking on our Tassimo and not knowing why.

Actually, the colour coding of the lights on Tassimo coffee machines is very simple, but often users do not know them or have not had them clearly explained to them. Anyway…. if you encounter red lights on your Tassimo, you don’t have to worry about it.

In this section, we will review some of the most common causes of problems with the lights of the Tassimo coffee machine:

All three lights are On

It can be for two reasons: you haven’t reset or initialised the brewer, or the capsule is incorrectly placed inside the brewing unit.

Cup-Shaped indicator: Red light does not go out

If the red light on your Tassimo coffee machine does not go out, the reason may be that the machine cannot read the barcode on the capsule you have used. Clean the reader, clean the capsule, or insert a new capsule.

Water tank red light

There is an indicator light in the shape of a water tap, which serves to warn us when the water tank is empty. It lights up when there is approximately 3 cm of water left.

If the red light on your Tassimo coffee machine does not go out, fill the tank (or if you have already filled it, check that it is properly connected or that the level meter is not stuck).

Descaler warning: Red light flashes

This one is easy: if the red light on your Tassimo coffee machine flashes, the machine is warning you to decalcify it. If the red light continues to flash, even though you have already decalcified the machine, you may have to repeat the process.

My Tassimo coffee machine has several lights On at once

It happens when the decalcification process is running, and in principle, it is not a problem. If all the LEDs are flashing red at the same time, then the machine may have power supply problems. The best thing to do in such cases is to wait a few minutes until the temperature of the coffee machine has stabilised or the electrical voltage has returned to normal levels.

Bosch Tassimo coffee machines: the orange button

Some of the more modern Bosch Tassimo coffee machines include a decalcification warning or alarm somewhat different from the old ones. It is the orange light on the Tassimo coffee machines. In others it’s red, but in the newer models, it’s orange. Its function, however, remains the same.

When the orange light on your Tassimo Bosch comes on, the machine is warning you that it is time to decalcify it because you have been using it for a long time without proper cleaning.

NOTE: It is important to practice decalcification when the machine is in decalcification mode (that is when it warns you, and not at any other time). If you do this, but the orange light is not on, your brewer “does not know” that you have decalcified it, and it will alert you again to do so.

My Tassimo coffee maker doesn’t recognise the capsule

If your Tassimo coffee machine does not read the code, the automatic reading system of the T-Discs will most likely not work due to the dirt. It’s obvious: if the reader is dirty, it can’t scan barcodes.

Immediate solution 1: clean the barcode reader of your coffee machine well, and try again with a new capsule.

Immediate solution 2: Make sure the barcode on the capsule is clean and wrinkle-free and also that the capsule is inserted correctly into the punch unit. If the capsule is embedded in a different position, its barcode cannot be scanned.

Long-term solution: prepare your coffees in manual mode (renouncing the automatic mode), although, of course, this way you take all the fun out of this brand of coffee maker.

The capsule explodes inside the Tassimo coffee maker

It is one of the most unpleasant problems that can happen to you with a Tassimo coffee machine, although fortunately, it is not too frequent. And we say this because the consequence is that, after hearing a dry blow – the capsule breaking – the coffee and the water being injected are thrown all around the capsule holder.

The good news is that this problem of the Tassimo capsule exploding inside the machine has nothing to do with a fault in your Tassimo coffee machine but with a leak in the T-Disc. At some point, the Tassimo capsule loses its vacuum, and the most frequent causes of this are usually a poorly sealed label, a hole or scratch on the lid, transport or careless handling.

It has no other solution than to be prevented and try to detect the defective T-Disc -without vacuum- before introducing it into the coffee machine.

The Tassimo coffee maker does not detect water

Well, the first thing (in case the flies get in) is to make sure your water tank is full and it’s properly connected to the coffee maker.

Once this routine check has been made, if the light on your Tassimo brewer continues to flash to indicate that it is not detecting water, try the following:

The water tank has a meter (a kind of black plastic cap, which floats on the water) that is used by the coffee maker to detect whether it is full or empty. Sometimes this water level gauge gets stuck, and the brewer doesn’t recognise it even though there’s water in it. In this case, all you have to do is move the gauge by hand – or with a tool that allows you to access it – to unlock it.

How to use the Tassimo coffee maker for the first time

If you’ve just bought one, you’re probably wondering how to use the Tassimo coffee maker, at least for its first use. So you don’t mess up, we’ll show you in the next video:

NOTE: Please note that all Tassimo coffee machines work in almost the same way, so the recommendations in this video apply to any Tassimo model.

How to restart the Tassimo coffee maker

All Tassimo coffee machines must be initialised or restarted before the first use or after a long period of inactivity. This is something that not all users are aware of – alas, that mania of not reading instruction leaflets – so we are obliged to remember it.

How do you initialise a Tassimo coffee machine? First of all, you have to take your service disc (the yellow T-Disc) that all Tassimo coffee machines have hidden in the back, start the coffee machine with it inside, and rinse the tank thoroughly to remove any dirt that may have been left inside.

Where’s the maintenance T-Disc?

The maintenance disc on Tassimo coffee machines is located in a compartment at the back of your coffee maker. All of them have it, without exception (well, if you have bought a second hand Tassimo coffee machine, we are not responsible).

In any case, if you need to buy a new maintenance T-Disc, or have an extra one as a spare, you can get it here:

  • Genuine Bosch / Tassimo
  • Suitable for Tassimo models TAS12.., TAS20.., TAS32.., TAS40.., TAS65.., TAS85..
  • Two Descaler Tablets
  • Tassimo Cleaning Disc (T-Disc)

Instruction manuals for Tassimo Bosch coffee makers

Whatever the fault of your machine, it can be beneficial to consult the user’s manual of the Tassimo Bosch coffee machines in their different models.

How to register my Tassimo coffee machine?

When you buy a new Tassimo coffee machine, you can register it on the website to join the MyTassimo club. It is none other than the Tassimo loyalty program (Dolce Gusto also had it at the beginning but closed it a few years ago), which gives you points and discounts as you buy your items within the brand (usually the capsules, of course).

And, of course, the first step and the early discounts come when you register your Tassimo coffee machine. You only need to know the serial number of the machine, which you can find in two places:

  • It could be in the promotional leaflet that must come inside the machine’s packaging.
  • Or in the coffee machine itself, in the lower part of the coffee maker (you will have to lift it to see it).

With this number, you only have to go to the official website and register your Tassimo coffee machine online. If you have any problems, you can also call the Tassimo customer service number.

How to decalcify my Tassimo coffee machine

It is a topic for an article of your own: how to decalcify a Tassimo coffee machine. We advise you to read it and comment on your impressions there.

We can tell you that the process is very similar to that followed in any other capsule or espresso machine. You pour a little decalcifying liquid into the water tank and start the coffee maker -without coffee- so that the diluted solution takes effect and circulates through all the internal pipes of the machine.

How to decalcify Tassimo without tablets

Closely related to the previous consultation, the usual question arises as to how to decalcify a Tassimo coffee machine without decalcifying tablets. The use of this type of product (which is still chemical, even though it is used for cleaning and disinfection) still arouses a lot of misgivings among a sector of consumers.

We recommend always using an official descaler liquid to clean your machine (whatever the brand is). Still, if for any reason you want to look for “homemade” alternatives, the best option is to decalcify your coffee machine with vinegar or lemon. In the attached link, you can learn more about this topic.

How do you clean the Tassimo coffee maker?

The guidelines for cleaning a Tassimo coffee maker are similar to those we can recommend for other brands of capsule coffee makers.

In addition to the usual routine external maintenance tasks (cleaning the coffee remains of all the parts so that the dirt does not accumulate and pass from the outside to the inside), there is also the regular cleaning of the water tank (which is more necessary when there is a higher level of lime or impurities in your city’s water) and the internal decalcification processes that we have already discussed in previous sections.

But, also, in the case of the Tassimo coffee machines, there is an additional peculiarity: the barcode reading system of the T-Discs. It is a critical system for the excellent functioning of both the coffee machine and the capsules, and to keep it in perfect condition, you must wipe it with a slightly damp cloth after preparing each coffee.

You should also have the T-Discs at hand, the well-known yellow (or orange, in some models) discs used to clean the inside of Tassimo coffee machines. They are very cheap, so you should always buy a spare Tassimo cleaning disc so that you don’t get unpleasant surprises when you need to make one.

How to dismantle a Tassimo coffee machine

We only recommend doing this as a last resort when you have run out of all other options and cannot take your Tassimo coffee machine to the technical service. If you decide to repair it on your own, the first thing you will have to know is how to open your Tassimo coffee machine, and then to understand how it looks inside, what each piece is and where each thing is.

This video shows you everything quite clearly and with the right level of detail. It belongs to a French user, but the images speak for themselves. It will undoubtedly help you if you want to dismantle your Tassimo coffee maker yourself:
