Nespresso: Problem-solving

Nespresso is undoubtedly one of the brands with the largest market share on the Internet. In this guide, we address the primary concern of our readers who are consumers or owners of a Nespresso coffee machine: the solution of problems and incidents with their coffee machine.

And since the queries are so many and so varied, we have compiled them here so that users have a clear and concise reference point in which to resolve their doubts with their Nespresso machine: common breakdowns, malfunctions, basic repairs, etc.

In cases where a more detailed explanation is required, we will provide the link to the post on our website where the problem related to any Nespresso Delonghi coffee machine is addressed. There are many breakdowns and explanations (or theories) as well.

As a general rule, it may also be interesting, in some cases, to check the user manuals of the Nespresso coffee machines in their various models. In any case, a little guidance is never a bad idea, especially if it is the first time you have had a problem with a Nespresso Krups or Delonghi coffee machine (the manufacturer is the least important in these cases). Anyway, let’s get started:

Nespresso Delonghi coffee makers: Breakdowns or failures?

What do Nespresso coffee machines fail to do? Well, there can be many causes. But before we start talking about solutions, a small note of clarification. When we have a problem with our Nespresso machine, we don’t necessarily have “a breakdown” or “a failure”. Often, these are situations that can be remedied but do not affect the functionality of the coffee machine.

We make this point because talking about breakdowns implies that something has gone wrong with the machine (in most cases, it has to do with the electric board), and therefore we have to take it to the technical service.

Solving a problem (a capsule that gets stuck, a part that has broken and needs to be replaced) is not a fault, and we can usually solve it on our own.

I have problems with my “Nespresso Krups” coffee machine

Well, we start with this one because it’s a classic among the classics. Readers who tell us about these symptoms cannot expect any diagnosis: Nespresso Krups is not a machine model.

As we have said many times on our page, Krups is a manufacturer (as is Delonghi too), so if you tell us that you have any problems with your Nespresso Krups coffee machine, we cannot help you much. You should look for the exact model – which is not Krups – and indicate it in your enquiry as well so that our community of readers can help you better.

The Nespresso coffee maker makes noise

Well, this is one of the examples we mentioned in the previous section. It is not a problem or a fault in itself. Not only the Nespresso, but all capsule coffee machines are slightly noisy. Indeed, some of the latest models (such as the Inissia) have triggered criticism of this fact. Still, the noise of the Nespresso machines is no more than anecdotal and even understandable.

We should not forget that the Nespresso Inissia was a coffee machine built and explicitly designed to be cheaper and more affordable than its predecessors (the firm’s commercial strategy demanded opening up to a broader public sector). And this decision is, of course, directly reflected in the materials.

You can learn more about noisy Nespresso coffee machines here.

The Nespresso coffee maker does not heat

When your Nespresso machine does not heat the water or the coffee does not come out as hot as it should, the problem can be in several places.

Firstly, we recommend that you decalcify the machine and clean it thoroughly. The accumulation of sediment in the boiler is often responsible for making the water take longer to heat up (not less). If this happens to you, it is normal that only the first coffee comes out colder than usual. Try several cycles without coffee and then the final coffee with your capsule—this way, the boiler should have had plenty of time to warm up.

On the other hand, if all the coffees are always cold, you are more likely to break down. Usually, you have to replace the Thermoblock (which heats the water before it goes out) or the thermostat (which regulates how hot it gets).

The Nespresso coffee maker is low on coffee

Here the problem always comes from excessive calcification. Leading solution: decalcifying your Nespresso.

In another order of priority, make sure that the capsule is original and that the coffee machine is capable of piercing it correctly.

In an extreme case, this problem can lead to the typical situation where no coffee comes out of your Nespresso machine.

Nespresso coffee machines without water pressure

In most cases, this problem is synonymous with the previous one. Nespresso coffee machines with low pressure are often caused by excessive decalcification. Sediment and limescale are deposited in the machine’s internal pipes, preventing the normal circulation of water (and therefore the coffee output).

Another possibility, if your Nespresso coffee machine has no pressure, is that the pressure pump has broken down, and therefore the water does not come out with the right strength. But we consider it a more remote option because when there is a breakdown in the pump, the logical thing is that the water does not even circulate, and therefore the coffee does not come out.

The Nespresso coffee machine does not pierce the capsules

And speaking of piercing, we have one of the most common problems here. When your Nespresso coffee maker doesn’t pierce the capsules or pierces them badly, coffee can’t come out (or it will come out in minimal quantities).

If your coffee maker doesn’t break the capsules, you can do two things:

  • Check the punch needle. Sometimes it bends or breaks, and since it’s such a small item, we don’t realize it until the coffee extraction fails.
  • Use official Nespresso capsules. You may not know this, but the latest models of Nespresso coffee makers have an anti-compatibility system that bends or disables the single pods in case they are not the official Nespresso pods.

The Nespresso coffee machine light is flashing

Flashing buttons on Nespresso coffee machines can mean several things. If your Nespresso Krups coffee machine keeps blinking, check one of these two possibilities:

  • Some machines are light and colour coded. If the long and short coffee buttons blink at the same time, the coffee maker may have activated its decalcification alarm. Solution: you have to decalcify it.
  • Sometimes, however, the coffee maker does not turn on at all. The Nespresso coffee machine keeps blinking a little, you try to press a button, and it switches off. In this case, the capacitors are failing. We will discuss this in the next section:

NOTE: To exit the flashing mode, or remove the decalcification warning, hold the buttons down for 5 seconds. The rapid blinking is relatively frequent on the Krups coffee machine, but do not alarm if it happens.

The Nespresso coffee machine does not work

It is another very common fault: your Nespresso coffee machine does not start. You plug it in, hit the button, and nothing. At best, the LED button lights flash slightly, and then the machine turns off completely. No coffee comes out of the Nespresso machine because it doesn’t even brew.

If this happens to you, we have two pieces of news for you: one good and one bad. The bad news is that your Nespresso machine is broken. The good news is that the repair is simple: almost all these problems happen because there is a defective or damaged capacitor (the main or auxiliary one). It is a very cheap component that you will find in any electronic parts store. All you have to do is know how to dismantle your Nespresso coffee machine and replace it.

This video explains it (but it is not in English); however, you can learn how to replace the capacitor by watching:

This solution can be used for almost all models of Nespresso coffee machines and even for other coffee machines of different types or brands, as they all have similar electronic boards. If you need to dismantle a Krups coffee machine, you can take this section as a reference to name but one.

The Nespresso coffee machine loses water

It is a problem common to many single-dose coffee machines and one that we have already dealt with more extensively here: my coffee machine is leaking water. There can be several causes for your Nespresso machine leaking water, so we recommend you read the full post.

Hint: if your Nespresso machine leaks water from the tank, the connection between the tank and the body of the coffee machine will usually fail.

My Nespresso machine does not release water

The opposite case to the previous one: the coffee machine turns on and seems to work well, but not a drop of water comes out when you press the button. Possible solutions:

  • Check that the water tank is not empty. It’s a truism, but better to be sure.
  • The water tank must be well connected to the base. Small maladjustment may cause the connector to be unconnected to the circuit, and there is no way of circulating the water from the tank to the interior.
  • Less likely option: failure of the pressure pump that pumps the water through all the pipes of the machine.

I have a leaky Nespresso machine

If your Nespresso machine leaks after making a coffee, it is probably due to a defect in the capsule or in the machine’s nozzle. In other words, the problem lies in the way the machine punctures the pods. You should check both issues.

To rule out a problem with the capsule, try several times over several days (just in case there is an isolated faulty capsule). Also, make sure you use official capsules because there are some Nespresso machines that do not fill compatible capsules properly.

If the capsule is not the problem, perhaps the problem lies in the injector, which is the small needle used to pierce the capsules and at the same time inject water into them. With use, it may have broken or bent a little. Any slight mishap can cause the water not to flow properly and your Nespresso machine to drip during or after brewing.

How do I reset the Nespresso coffee machine?

Resetting the Nespresso coffee machine is a straightforward process, which means returning the settings of the volume buttons (long and short coffee). As you know, many Nespresso coffee machines allow you to define and customise the values (amount of water) to be used for traditional espressos and Lungos.

To restore your Nespresso coffee machine to its factory settings, press the right button (the lungo coffee button) and switch the coffee machine off/on with this button pressed. Hold it down for 5 seconds.

As you can see, the Nespresso lungo coffee is used for more than just waking up in the morning.

Nespresso Coffee Machine: Stuck Capsules

It is a similar problem to the one we discussed in this article for Nestlé’s other coffee machines:

Of course, the solution is also similar: never force the lever or try to remove the capsule stuck in your Nespresso. You will most likely end up breaking something or damaging the mechanism. If your Nespresso machine does not open, be patient and gentle when you act.

And in this case, prevention is much better than cure: remember always to remove the capsule when you use it (applicable only to Dolce Gusto coffee machines that do not have a deposit of used capsules).

Does the Nespresso coffee machine make chocolate?

No, it does not. Do not insist. The Nespresso machine does not make chocolate, no infusions, no lattes or anything else. The Nespresso machines, if you use official Nespresso capsules, only make black coffee.

So don’t try to pour milk into the tank of the machine, or similar burritos, because it won’t work, and you’ll most likely ruin your coffee machine.

Can I pour milk into the water tank?

Never! We don’t know why many users are bent on this sort of aberration against single-dose coffee machines.

Let’s be clear: Nespresso coffee machines (and any other espresso) run on water and are designed to work with water. Milk has fats, sugars and a host of other qualities that will cause residues and unexpected consequences when it passes through the internal circuit of the coffee maker.

And another thing: did you ever stop to think that milk has a different boiling point than water?
