2. Important Safety Instructions

Please read all instructions carefully before operating the Bezzera Aria Top PID Espresso Machine. Retain this manual for future reference.

• Electrical Safety: Ensure the machine is connected to a grounded outlet with the correct voltage. Do not immerse the machine, cord, or plug in water or other liquids. Unplug from the outlet when not in use and before cleaning.
• Hot Surfaces: The machine's surfaces, including the grouphead, steam wand, and hot water spout, become very hot during operation. Use handles and knobs, and allow the machine to cool before handling hot parts.
• Water Tank: Only fill the water tank with fresh, clean, potable water. Do not operate the machine without water in the tank.
• Children and Pets: Keep the machine out of reach of children and pets. Supervise children if they are near the appliance.
• Maintenance: Do not attempt to repair the machine yourself. Refer all servicing to qualified service personnel.
• Placement: Place the machine on a stable, level, heat-resistant surface, away from walls or cabinets to allow for proper ventilation.

4. Initial Setup

1. Unpacking: Carefully remove the machine from its packaging. Retain all packaging materials for future transport or storage.
2. Placement: Place the machine on a sturdy, level, and heat-resistant surface. Ensure adequate clearance around the machine for ventilation.
3. Water Tank Preparation: Remove the water tank, rinse it thoroughly with fresh water, and fill it with cold, filtered water. Reinsert the tank securely into the machine.
4. First Use Flush: Before first use, or after extended periods of non-use, perform a system flush.
   • Ensure the water tank is full.
   • Insert the portafilter without coffee.
   • Place a large container under the grouphead and hot water spout.
   • Plug in the machine and turn on the main power switch. The machine will begin to fill the boiler.
   • Once the boiler is full and the machine has heated to operating temperature (indicated by the PID display), open the hot water valve to dispense about 500ml of water. Close the valve.
   • Engage the brew lever for 10-15 seconds to flush the grouphead. Repeat this 2-3 times.
5. Heating Up: Allow the machine to fully heat up for at least 20-30 minutes. This ensures the E61 grouphead and portafilter are at the optimal temperature for extraction.

5. Operating Instructions

5.1. Making Espresso

1. Prepare Portafilter: Grind fresh coffee beans to an espresso-fine consistency. Dose the appropriate amount into the portafilter basket (e.g., 18-20g for a double shot). Distribute the grounds evenly and tamp firmly with consistent pressure. Wipe any loose grounds from the rim.
2. Insert Portafilter: Lock the portafilter securely into the E61 grouphead.
3. Place Cups: Position pre-warmed espresso cups under the portafilter spouts.
4. Start Extraction: Lift the brew lever fully to begin the extraction. Observe the brew pressure gauge.
5. Flow Profiling (Optional): Use the flow control lever to adjust the water flow rate during extraction. This allows for pre-infusion or varying flow to highlight different flavors.
6. Stop Extraction: Lower the brew lever once the desired espresso volume or extraction time is reached (typically 25-30 seconds for a double shot).
7. Clean Up: Remove the portafilter, discard the spent coffee puck, and rinse the portafilter under hot water.

5.2. Steaming Milk

1. Prepare Milk: Fill a stainless steel milk pitcher with cold milk (dairy or non-dairy) to just below the spout.
2. Purge Steam Wand: Open the steam valve briefly to purge any condensed water from the wand. Close the valve.
3. Position Wand: Immerse the tip of the steam wand just below the surface of the milk.
4. Steam Milk: Open the steam valve fully. Listen for a gentle "tearing" sound as you introduce air into the milk. Once the milk has expanded and reached desired volume, lower the pitcher slightly to immerse the wand deeper and create a swirling vortex for texturing.
5. Monitor Temperature: Continue steaming until the pitcher is too hot to touch (approx. 60-65°C / 140-150°F).
6. Clean Wand: Close the steam valve. Immediately wipe the steam wand with a damp cloth to remove any milk residue. Purge the wand again briefly to clear the internal passage.

6. Maintenance and Cleaning

Regular cleaning and maintenance are crucial for the longevity and optimal performance of your Bezzera Aria Top PID Espresso Machine.

• Daily Cleaning:
  • Grouphead: After each use, remove the portafilter and rinse it. Use a grouphead brush to clean any coffee grounds from the grouphead gasket and shower screen.
  • Drip Tray: Empty and rinse the drip tray daily.
  • Steam Wand: Always wipe and purge the steam wand immediately after steaming milk.
• Weekly Cleaning (Backflushing):
  • Insert a blind filter basket into the portafilter.
  • Add a small amount of espresso machine cleaning detergent (e.g., Cafiza) to the blind filter.
  • Lock the portafilter into the grouphead.
  • Engage the brew lever for 10 seconds, then disengage for 5 seconds. Repeat this cycle 5-6 times.
  • Remove the portafilter, rinse it, and repeat the backflushing process with plain water to remove any detergent residue.
• Descaling (Every 2-3 Months or as needed):

  Descaling removes mineral buildup from the boiler and internal components. Use a descaling solution specifically designed for espresso machines. Follow the descaling product's instructions carefully. Ensure the machine is cool before starting the descaling process.

• Water Tank: Clean the water tank regularly with mild soap and water to prevent algae or mineral buildup.
