Why My Dolce Gusto Coffee Machine No Longer Leaks?

Aug 05, 2023, 15:09pm

It happens that your Dolce Gusto Krups coffee maker no longer flows: you put in your coffee or espresso capsule and the water does not flow. Generally, it is more often due to a lack of maintenance and descaling than a defective part. It is important to clean and descale the coffee maker so that it does not become clogged with scale and limescale. It will be necessary to do this regularly, depending on how often you use it.

If the coffee from your Dolce Gusto Krups does not flow, you will need to unclog the nozzle where the coffee flows, descale and examine certain parts that may be the cause:

  • Clean the tank filter
  • Check the nozzle
  • Check the coffee maker pump
  • Check the boiler

These different tests will help you, if unclogging and descaling the coffee machine has not solved your problem of a Dolce Gusto coffee maker that no longer flows or is clogged.

If your coffee machine displays the message “Calc” (limestone), it means that you must first descale it to solve the problem.

Having a coffee machine leak is a common and annoying issue that many users face. However, when it comes to Dolce Gusto coffee machines, they are designed with several features that can prevent leakage if maintained properly. If you’ve recently found that your Dolce Gusto coffee machine no longer leaks, it could be due to a number of factors. This article explores the potential reasons.

Why My Dolce Gusto Coffee Machine No Longer Leaks?

1. Proper Seating of Components

Pod Holder Alignment

The Dolce Gusto machine’s pod holder must be correctly aligned and seated for a proper brew. If misaligned, it may cause leaks. Correct alignment of this component can prevent leakage.

Water Tank Seating

Ensuring that the water tank is seated properly, without any gaps, can prevent water from leaking out of the reservoir.

2. Replacement of Worn Parts

Gaskets and Seals

Over time, gaskets and seals may wear down and lead to leaks. Replacing these components with fresh, new parts will often resolve the leakage issue.

Water Lines and Connections

Any cracks or damages to water lines and connections may cause leakage. Repair or replacement of these parts can stop the leaks.

3. Regular Maintenance and Cleaning


Regular descaling removes mineral build-up that might lead to leaks around various seals and connections. Following the manufacturer’s guidelines for descaling can maintain the integrity of these components.

Cleaning of the Drip Tray

Keeping the drip tray clean and free of obstruction allows the spillage to flow freely into the tray, making it appear as if the machine has stopped leaking when it was actually just a misinterpretation of normal operation.

4. Correct Pod Usage

Using the correct type and size of coffee pods designed for your Dolce Gusto model ensures a perfect fit and seal, minimizing the chances of leakage.

5. Professional Servicing

If you’ve recently had your Dolce Gusto machine serviced by a professional, they would have inspected and repaired any potential issues leading to leaks. This could include tightening connections, replacing worn parts, and ensuring proper alignment of all components.

6. Machine Upgrade or Adjustment

If you’ve recently upgraded to a newer Dolce Gusto model or made any adjustments to the settings as per the user manual, these changes might have resolved any prior leakage issues.


To see if the nozzle is clogged and the coffee maker is blocking the flow, start by disassembling the device.

  • Remove the tank and any other items that can be easily removed.
  • Behind the tank in the middle of the machine is a support spring, resembling a small needle.
  • Directly above the capsule holder is a nozzle that pierces the capsule. Using a spring, clean the nozzle.


Lack of pressure or a faulty pump can cause your Dolce Gusto coffee maker to stop leaking. As a rule, the pump is located directly above the tank, because these two elements are connected by one hose.

  • Check if the hose is clogged by pulling it out by hand and inspecting or manipulating it.
  • Using a multimeter, set the position of the central switch to the maximum value in kΩ.
  • Disconnect the terminals from the pump and put the test leads on the pump connectors. If you find 0, 1 or OL, the pump will have to be replaced.


The reason your Dolce Gusto coffee machine no longer leaks can be attributed to various factors such as proper alignment of components, replacement of worn-out parts, regular maintenance, correct pod usage, professional servicing, or even an upgrade or adjustment of the machine.

Ensuring that all the parts are in good condition, aligned properly, and that the machine is regularly cleaned and descaled will help in maintaining a leak-free operation.

If leakage ever recurs, it’s essential to refer to the user manual or contact a professional technician to diagnose and resolve the issue, as ignoring a leak can lead to more significant problems in the long run.
