If your espresso machine is making a loud or unusual noise, it’s essential to understand the possible causes and solutions. By addressing the knocking issue promptly, you can ensure the efficient and reliable performance of your machine.
One common cause of knocking sounds in an espresso machine is the incorrect placement of the water tank. If the tank is not fully pushed back or has dirt and particles, it can create vibrations and noise during operation. To resolve this, make sure the water tank is correctly inserted and free from any debris.
Another potential problem is air trapped in the machine, which can lead to loud noises and hinder the water flow. If you suspect air is trapped, follow specific steps to release it. Switch off the machine, empty the water tank, fill it with water, and produce a few cups of hot water. This process helps restore the normal functioning of the machine.
If the knocking noise persists, it could be due to a dirty brew group. Regular cleaning and greasing of the brew group can significantly reduce noise levels. Rinse the brew group weekly and follow the provided instructions for proper maintenance.
If none of these solutions resolve the knocking issue with your espresso machine, it’s advisable to seek further assistance. Contacting customer support will ensure expert guidance and help diagnose any underlying problems with your machine.
Key Takeaways:
- Ensure the water tank is correctly inserted and free from dirt or particles to prevent knocking noises in your espresso machine.
- If air is trapped in the machine, follow specific steps to release it, including emptying the water tank, filling it with water, and dispensing hot water.
- Regularly clean and grease the brew group to maintain optimal performance and minimize knocking sounds.

Troubleshooting Water Tank Issues
One common cause of knocking sounds in an espresso machine is an incorrectly placed or dirty water tank. It’s important to ensure that the water tank is properly inserted and free from any dirt or particles. Depending on the machine’s design, this may require pushing the tank back fully or checking the area beneath it.
If air is trapped in the water tank, it can result in loud noise and the water not being drawn into the machine. To resolve this issue, follow these steps:
- Switch off the machine.
- Empty the water tank.
- Fill the water tank with water.
- Dispense a few cups of hot water.
If you are using an AquaClean water filter, additional steps should be followed. Regular maintenance is crucial to prevent clogging. Make sure to replace the AquaClean filter every three months to maintain optimal performance.
By addressing water tank issues, you can eliminate knocking sounds and ensure that your espresso machine functions smoothly. Proper maintenance and regular cleaning can prolong the lifespan of your machine and enhance your coffee brewing experience.
Dealing with Air Trapped in the Machine
When air becomes trapped in an espresso machine, it can lead to disruptive loud noises and hinder the machine from drawing water properly. Resolving this issue requires a few simple steps that can be performed at home.
- Switch off the machine: Begin by turning off the espresso machine to ensure safety and prevent any mishaps during the troubleshooting process.
- Remove any water filters: If your machine has a water filter, take it out before proceeding with the troubleshooting steps.
- Fill the water tank: Ensure that the water tank is adequately filled with water, as this will be crucial to releasing the trapped air.
- Dispense hot water: Once the machine has heated up, dispense a few cups of hot water through the brew head or group. This will help release the trapped air and restore normal functionality to the machine.
By following these steps, you can effectively resolve the issue of air trapped in your espresso machine. This simple troubleshooting technique can often eliminate noisy disruptions caused by air pockets and ensure your machine delivers a smooth and enjoyable brewing experience.
If you are using an AquaClean water filter, it is important to note that additional steps may be required to properly prepare and install the filter. Refer to the manufacturer’s instructions for the specific guidelines to follow.

Cleaning and Greasing the Brew Group
Over time, the brew group of an espresso machine can become dirty and require cleaning and greasing. While it is normal for the machine to make some noise during brewing, unusual noises may be an indication that the brew group needs attention.
To clean the brew group:
- Switch off the machine.
- Remove the brew group.
- Thoroughly rinse the brew group with lukewarm water.
- Air-dry the brew group.
- Grease the brew group according to the provided instructions.
Regular maintenance, such as weekly rinsing, is crucial to maintain the performance of the brew group and reduce knocking noises.
