Tassimo: Common Problem-Solving Help Guide




Tassimo is a smart coffee maker that allows you to brew your favorite beverages at home. The device has a built-in water filter and comes with a variety of pre-programmed recipes.

Tassimo was founded in 2012 and is headquartered in San Francisco. They currently sell their devices in over 50 countries worldwide.

This is one of the most popular capsule coffee maker systems in the world. However, it doesn’t always work perfectly all the time. Like any machine, the Tassimo machine can have its moments where it doesn’t want to work.

In this article, we will be discussing some of the most popular and frequent concerns and questions customers have had regarding their Tassimo machine not working.

We will be solving all of your issues, so you can enjoy your Tassimo machine once again.

Tassimo Machine Not Heating

You may have noticed that your Tassimo machine isn’t heating the water in the machine. There are two main reasons why this problem may be occurring, and they are both to do with the same component in the machine.

The first thing you should do is perform a full descaling of your machine. This is because if you haven’t descaled your Tassimo machine for a while, then impurities and sediment may have built up.

This will then stop the water from being able to circulate properly to and from the boiler. Or there may be an issue with the boiler itself. This isn’t as common to happen, but it does sometimes.

When this does happen, then you will need to replace the boiler. A new boiler for your machine isn’t cheap, so you should keep on top of descaling your machine.

Tassimo Is Losing Water

It can be annoying when you notice some water under your Tassimo machine. This is normally due to some small leaks.

These leaks aren’t a huge problem, but they can be annoying to clean up. However, there are two reasons for this issue occurring.

The common reason is that the drip tray is full. It is easy to forget to empty the drip tray. If it isn’t empty then eventually the drip tray will overflow which causes these small leaks every time you use your machine and make a coffee.

The other reason your Tassimo machine is losing water is that the capsule piercing unit or water tank isn’t correctly fitted.

Both use millimeter-tight fittings, and sometimes they may not be fitted properly, even if they seem like they are. Therefore, if they’re not fitted properly, then the water won’t be able to flow through and around them properly.

Thus, the water will then come out under the machine, which isn’t supposed to happen.

It is useful to dismantle and clean the coffee plunger and jet. This is because residues of coffee can block the coffee flow, which then causes water to leak.

However, if none of these methods work then you need to disassemble the machine to be certain all the pumps and popular are clean and connected.

Red Light Is Flashing

There are a couple of lights on a Tassimo machine, and they can be confusing for a lot of people to what they mean. However, the lights on the Tassimo coffee machine are color coded and are quite easy to understand.

If you do see a red light on your machine, you don’t need to worry. There are a few reasons why you may see a red flashing light, and we are going to go through them all now.

Three Red Flashing Lights

If you notice three red flashing lights, this can be due to two reasons.

The first being that there is an internal problem, which was caused by turning your machine on or off. It could also mean a power issue as well.

What you should do is unplug your Tassimo machine and leave it for 10 seconds. Then you can re-plug it back in.

This normally solves the issue, but if it doesn’t then you may have a damaged electric board, which will need to be replaced.

The second reason you are seeing three red flashing lights is because you have placed the coffee pod the wrong way into the brewing unit. You need to make sure that you put the capsule in the correct way.

Red Cup-Shaped Indicator Won’t Go Out

Sometimes a red light on your machine won’t go out. This is normally due to your coffee machine not being able to read the barcode on the capsule that you have inserted into the machine.

In this case, you need to clean the pod and the reader. It is also worth inserting a new pod as well, in case the pod that you originally inserted was faulty.

Red Light On Water Tank

On your Tassimo machine, you will notice a tap-shaped indicator. This will turn red when the water tank is empty and needs to be refilled. It should light up red when there is only 1 inch of water remaining in the tank.

The best thing to do is fill the water tank, and this should cause the red light to go out.

However, if you have filled the water tank and the light is still there, make sure that you have connected the water tank correctly. Also check to see if the level gauge is not stuck.

Flashing Red Descaler Light

If you see a red light that is flashing red, this is your Tassimo machine telling you it needs to be descaled. Even if you have descaled the machine recently, you may need to repeat the process again if the light is still flashing.

Several Lights Are On At Once

This is a common thing to happen during decalcification. Although, this isn’t really an issue. If all the LED lights on your Tassimo are flashing red, then this could also be a sign that the machine is having power supply issues.

In this case, you should wait for a couple of minutes for the machine to stabilize and the temperature to drop. This helps the voltage levels return to normal, before you try to use it again.

Orange Light On Spray Icon

On the more modern Tassimo machine, the descaling warning is red, but on an older model the color was originally amber/orange.

When you notice an orange colored light on the spray icon, this is another warning to descale your Tassimo machine.

You should make sure that you descale and clean your machine properly so that it can run smoothly.

When it comes to descaling your Tassimo machine, you should do it when you are running the decalcification process.

Capsule Isn’t Recognized By The Machine

It sometimes happens when your Tassimo machine can’t read the barcode that is on your coffee capsule.

This is normally due to the reading system and T-discs not working properly because they are dirty. If your reader is dirty, then it will not be able to read the coffee capsules.

To solve this issue, you can clean the barcode reader and use a new coffee capsule. Hopefully, once the reader is clean, it will start working again.

Alongside this, you need to make sure the barcode on your capsule is clean and wrinkle free. Make sure that you place the capsule correctly into the brewing and piercing unit. If the capsule isn’t fitted incorrectly, then the barcode can’t be read either.

Exploding Capsule

It is something that no one wants to happen, but it does. It is actually a much more common issue than people would expect. When a capsule does explode, you hear the band and water and coffee will spill all over the capsule holder.

Although this problem has nothing to do with your Tassimo machines, it’s the capsules fault. However, you should be careful if your capsule does explode as it may leak onto the T-Disc, which will need to be cleaned afterwards.

The reason the capsule explodes is that the capsule loses the vacuum it has created. This is normally due to a bad label seal, or there may be scratches or holes on the lid that disrupts the vacuum.

There is no real solution to this problem, apart from handling your coffee capsules with care and trying to identify ones that might be defective and could explode.

Machine Not Detecting Water

Sometimes your Tassimo machine may say that it isn’t detecting water, the first thing that you should do is see if the water tank needs to be refilled.

Alongside this, you can make sure that the tank has been connected properly to the coffee machine. Once these routine checks have been completed, if the light still says that there is no water being detected, then you can try the following things.

Every water tank has a gauge. This is a plastic, black cap which you will see floating in the water tank. This is what is used to detect whether the water tank needs to be refilled.

However, sometimes this gauge doesn’t always work and becomes stuck. As a result, the machine doesn’t believe that the water tank is full, as it can’t detect it. In this scenario, you need to move the gauge with a tool or by hand to unblock it.

However, the gauge is also magnetic. In some less common cases, the magnetic feature will stop working. Therefore, you will have to replace the gauge or the magnetic.

Unfortunately Tassimo at the time, didn’t sell any magnets separately, so you had two choices. Either you buy a new water tank or you purchase a small magnetic form somewhere else to replace the magnet in the gauge.

Restarting A Tassimo Machine

It is common for your Tassimo machine to reset itself before you first use it or if it hasn’t been used for a long period of time.

The majority of people who own a Tassimo don’t realize that this will happen, so we felt it was important that you don’t forget it.

If you haven’t used your Tassimo for a long time, then it is important to clean the yellow maintenance T-Discs, alongside the water tank. This is so you remove any dirt that may still be in the machine since you last used it.

The maintenance discs are found on the underside of your coffee machine.

Descaling A Tassimo Machine

It is quite easy to descale a Tassimo machine, there are a couple of ways to do this. Yet, the way most people do it is by adding some descaling liquid into the water tank and running the machine.

This allows the liquid to circulate around the machine into all the pipes and ducts and give it all a good clean.

You can also use lemon, or vinegar as a descaling liquid if you don’t want to buy the commercial liquid.


In this article, we have answered some of the most common issues that people have found with their Tassimo coffee machines.

We hope this article has answered all of your questions, so that you can go back to enjoying your freshly brewed coffee in your Tassimo machine.
