My Dolce Gusto coffee machine has run out of water
If your Dolce coffee maker has run out of water, the first thing you should check is that the tank is full. It’s a truism, but sometimes we forget (especially if we have the coffee maker in a corner and can’t check the fill level with the naked eye). Once full, the coffee maker should work safely.
Secondly, and to rule out water loss or leakage that indicates a significant fault, we recommend that you read the following guide: what to do if my Dolce Gusto coffee maker loses water.
My Dolce Gusto coffee maker does not water
If your coffee maker appears to be correctly installed and arranged (i.e. the plugin, the socket and the tank filled with water), and when you start it up, the water does not circulate, do not be alarmed: there is still a chance that there is no fault. It may only be that the tank is poorly connected (and then the water cannot get out of it).
If the water does come out of the tank and circulates inside, but doesn’t reach the filter (i.e. no coffee comes out of the brewer), then there are probably blockages inside the pipes, and it’s up to you to investigate further.
We’ll expand on this, along with some extra possibilities, in this much more comprehensive article: The coffee maker doesn’t pour water.
Dolce Gusto coffee maker without pressure
A Dolce Gusto coffee maker without pressure strength is one of the worst news for espresso lovers. No coffee or brewing will be the same, but the lack of pressure in a coffee maker is especially noticeable when extracting the short brews: espressos and ristrettos.
If your Dolce Gusto coffee maker has no water pressure, it could be because the coffee machine is stuck or because the accumulation of sediment and impurities is such that it prevents the normal circulation of water inside the coffee machine. In the latter case, you should decalcify your coffee maker as soon as possible. In the following section, we explain how.
Finally, and less likely, the breakdown may be related to the injector.
My Dolce Gusto does not heat
Something similar happens when neither the coffee nor the rest of the drinks come out at the average temperature. If you’ve been using your machine for a while, and you notice that the coffee isn’t as hot as it used to be, the number one solution is always to do a decalcification. Usually, too much lime has built up in the Thermoblock, and the coil can no longer heat up as it did when it was new.
The second, much less desirable alternative is a failure in the heating system. In this case, it is necessary to replace the entire Thermoblock and for this, you will probably have to be a handyman or take your machine to a Dolce Gusto repair service.
Dolce Gusto coffee machine: How to decalcify
Decalcification of coffee machines is a very common and necessary operation in the long-term maintenance of any coffee machine. And as you will see, it is very much related to the solution or prevention of many of the problems that we describe in this guide.
The process is quite simple, but if you’ve never done it before or you’re not sure how to remove limescale from a Dolce Gusto coffee machine, then check out the following articles (especially the first one):

Dolce Gusto coffee maker: How to clean it
It is very much related to decalcification, which we talked about earlier. The cleaning of the coffee machine covers two areas: the external and the internal. And this last one sometimes we don’t take care of it as much as we should. If you want to keep up to date and know how to clean a Dolce Gusto coffee maker, don’t miss the next article: How to clean a Dolce Gusto coffee maker.
How to repair a Dolce Gusto coffee machine
We arrive at a broad and generic chapter, which gives to play many different sticks. Everything you need to know about repairing a Dolce Gusto coffee maker can be found in this article: how to repair a Dolce Gusto coffee maker.
Dolce Gusto coffee maker: How to dismantle it
Sometimes it is not enough to do some cleaning or any superficial operation. The Dolce Gusto coffee machine must be dismantled to access the repair or replacement of any internal component (electric plate, pumps, pipes, etc.).
If you don’t know how to open a Dolce Gusto coffee maker, then look at this video. It will be handy if you want to avoid the trance of taking it to the technical service.
Worms inside the Dolce Gusto coffee maker?
Here’s one of our favourite myths. We’re not going to lower it to the level of urban legend, but almost. The cases that have happened are very isolated and have a logical explanation (and to make matters worse, they are far from exclusive and cannot be linked only to the coffee makers or the capsules of the Dolce Gusto system). For more information, you can read here.
My Dolce Gusto Piccolo coffee machine doesn’t turn on
“My Dolce Gusto coffee maker does nothing“. Another super frequent query from our readers. You plug it in, press the power button, wait a few seconds, and nothing happens. Sometimes maybe the green button flashes, but suddenly the machine turns off. And there’s no way to revive it or make it work. Does this situation sound familiar?
All these problems have to do with the electric plate of the coffee machine, and more specifically, with the capacitors. We tell you everything here: what do I do if my Dolce Gusto coffee maker doesn’t turn on?
My Dolce Gusto coffee maker turns itself off
It is a variation of the previous problem. Sometimes the machine does turn on, but after a few seconds, the Dolce Gusto coffee maker turns itself off. You can see the button light up, usually in red, but then you can’t do anything else.
The most likely cause is the same as we mentioned before: defective capacitors, which can cause a voltage drop when the machine is switched on.
Here is a video that can help you to know how to solve this problem (Dolce Gusto coffee maker without power) by yourself:
My Dolce Gusto coffee maker doesn’t turn green light
It is just one version of the dozens of possibilities and confusions that users have with the colour-coding of Dolce Gusto coffee machines. You know that the start button of the coffee maker can be illuminated in three colours (red and green, and orange in some recent models), and each colour can be fixed or blinking.
And of course, the combinations are endless:
- My Dolce Gusto coffee maker flashes red.
- The Dolce Gusto coffee maker flashes red and green.
- The yellow indicator on the Dolce Gusto coffee machine.
- My Dolce Gusto keeps blinking.
- And we could go on with many more.
And you know what the worst part is? Each one of them means something different. So here is a complete article. We summarize all the incidents and possible solutions related to the lights of a Dolce Gusto coffee machine: Problems with the Dolce Gusto power button.
My Dolce Gusto coffee machine drips
There may be several cases here, but almost all of them, unfortunately, involves the possibility that there is a fault or some problem that needs to be solved. Frequently, one of these two situations should happen to us:
- My Dolce Gusto coffee machine is leaking water underneath: this means that the water tank is leaking, or a hose is broken inside the machine. You will need to open the coffee machine, find out where the damage is, and replace the damaged element.
- My Dolce Gusto coffee machine is leaking water from the top. In this case, the problem is more likely to be related to the capsule or capsule holder and does not necessarily involve a technical fault.
See the following article to learn more: Problems with Dolce Gusto coffee machines: water loss.
My Dolce coffee machine makes a lot of noise
Well, we’re sorry, but we can’t help you much here. Espresso machines (both capsule machines and arm machines with ground coffee) always make some noise, for the simple reason that they must pump water at high pressure for the result – the espresso – to come out in the optimum condition.
Besides, any water heating process (all Dolce Gusto machines use Thermoblock) also involves slightly noisy activity.
So, the noise from Dolce Gusto coffee machines does not imply any fault, no problem, nothing that can be “solved”. It is inherent in the type of coffee they make. The same is true of Nespresso machines.
