3. Setup

1. Cleanliness: Before first use, wash the portafilter and filter basket with warm, soapy water and rinse thoroughly.
2. Insert Filter Basket: Place the desired filter basket (e.g., 2-cup) into the portafilter head. Ensure it sits flush and securely.
3. Pre-heat: For optimal espresso extraction, it is recommended to pre-heat the portafilter. Lock the empty portafilter into your espresso machine's group head and run a blank shot of hot water through it. This brings the portafilter to the correct temperature, preventing heat loss during extraction.
4. Grind Coffee: Grind fresh coffee beans to an appropriate fineness for espresso. The ideal grind size is crucial for proper extraction.
5. Dose: Add the correct amount of ground coffee into the filter basket. For a 2-cup basket, this is typically 14-18 grams, depending on your preference and coffee type.
6. Distribute: Evenly distribute the coffee grounds within the basket. Uneven distribution can lead to channeling.
7. Tamp: Using a tamper, apply firm and even pressure to compress the coffee grounds into a level puck. Consistent tamping is essential for uniform water flow.

4. Operating Instructions

1. Prepare Portafilter: After pre-heating (as described in Setup), remove the portafilter from the group head. Wipe the filter basket dry to remove any excess water.
2. Load Coffee: Dose, distribute, and tamp your ground coffee into the filter basket.
3. Insert into Machine: Carefully insert the prepared portafilter into the group head of your Neretva CP6100U espresso machine. Twist the handle firmly to the right until it is securely locked in place.
4. Start Extraction: Initiate the espresso extraction process according to your specific espresso machine's operating instructions.
5. Monitor Flow: Observe the espresso flow. An ideal extraction typically starts with a few drops, then forms a steady, mouse-tail-like stream.
6. Stop Extraction: Stop the extraction when the desired volume or time is reached, usually around 25-30 seconds for a double shot.
7. Remove Portafilter: Carefully remove the portafilter by twisting the handle to the left. Be cautious as the portafilter and its contents will be hot.

5. Maintenance

• After Each Use: Immediately after removing the portafilter, knock out the used coffee puck. Rinse the portafilter and filter basket thoroughly with hot water to remove any residual coffee grounds and oils.
• Regular Cleaning: Periodically, deep clean the portafilter and filter basket. This can be done by soaking them in a solution of espresso machine cleaning detergent (follow detergent instructions) or by scrubbing with a brush and hot, soapy water.
• Drying: Ensure all parts are completely dry before storing to prevent water spots or potential corrosion.
• Inspect Gasket: Regularly inspect the rubber gasket within your espresso machine's group head for signs of wear or cracking. A worn gasket can lead to leaks and poor extraction.

6. Troubleshooting

• Uneven Extraction / Channeling:
  • Grind Size: If water flows too quickly or unevenly, the grind might be too coarse. If it flows too slowly or not at all, the grind might be too fine. Adjust your grinder settings accordingly.
  • Distribution: Ensure coffee grounds are evenly distributed in the filter basket before tamping. Use a distribution tool if available.
  • Tamping: Apply consistent and even pressure when tamping. An uneven tamp can create weak spots in the coffee puck, leading to channeling.
  • Reference: Review Video 1 for visual guidance on identifying and correcting channeling issues.
• Difficulty Locking Portafilter:
  • Cleanliness: Check for coffee grounds or debris on the rim of the filter basket or the group head gasket. Clean thoroughly.
  • Overdosing: Ensure you are not overfilling the filter basket, which can prevent the portafilter from locking properly.
• Leaking from Portafilter:
  • Secure Lock: Ensure the portafilter is fully and securely locked into the group head.
  • Gasket Condition: Inspect the group head gasket for wear, cracks, or hardening. A worn gasket may need replacement.
