4. Instruccions de funcionament

Once the puck screen is in place, proceed with your normal espresso brewing routine. The screen will help distribute water evenly over the coffee grounds, promoting a more consistent and flavorful extraction.

1. Lock the portafilter into your espresso machine's group head.
2. Initiate the brewing process as usual. Observe the even flow of espresso from your portafilter.

5. Manteniment i Neteja

Regular cleaning of your puck screen is essential to maintain optimal performance and hygiene. The MHW-3BOMBER puck screen is designed for easy cleaning.

1. After each use, remove the puck screen from the portafilter.
2. Rinse the puck screen under running water to remove any residual coffee grounds. Its design prevents fine powder from hiding, making it easier to clean than many other screens.
3. For deeper cleaning, especially if you notice any buildup, soak the screen in a solution of espresso machine cleaner (e.g., Urnex or Puly Caff) and hot water.
4. Rinse thoroughly after soaking and allow to air dry.

6. Solució De Problemes

If you experience issues with extraction despite using the puck screen, consider the following:

• Extracció desigual: Ensure your coffee grounds are evenly distributed and tamped level before placing the puck screen. The puck screen aids distribution but cannot correct severely uneven tamping.
• Flux lent o ràpid: Adjust your grind size. A grind that is too fine can lead to slow extraction, while a coarse grind can result in a fast, watery shot.
• Puck Screen Not Fitting: Verify that you have the correct size (58.5mm) and the appropriate design (with or without a round hole) for your specific espresso machine and portafilter.

For further assistance, if the extraction effect is not satisfactory, you can contact customer service with your extraction parameters (portafilter basket size, powder weight, grinding degree, tamping pressure) for professional advice.
