How to Program Volumetrics – Linea PB AV

⚡ Before you start

• Machine should be on and warmed up (groups at operating temp).

• Have a scale and shot glasses handy to measure yield.

• Use the same coffee and recipe you plan to serve.

• Make sure you’re programming the correct group head (each group can be set independently).

🔧 Steps to Program a Volumetric Dose

1. Enter programming mode

   • On the PB, press and hold the continuous flow button (the far-right button with the infinity symbol) for about 5 seconds until the LED above it blinks.

   • You are now in programming mode.

2. Select the button you want to program

   • Choose which volumetric button (single, double, triple, etc.) you want to program.

   • Press that button once — the machine will start brewing.

3. Pull your programmed shot

   • Let the espresso run until you reach the desired output (e.g. 36 g yield for a double shot).

   • Press the same button again to stop the flow.

   • The machine now memorises that volume.

4. Repeat for other buttons

   • Program each button (single, double, etc.) following the same process.

5. Exit programming mode

   • When finished, press the continuous flow button again.

   • The LED will stop blinking, confirming programming is saved.

✅ Tips for Best Results

• Purge before programming — always flush the group before pulling your programmed shot.

• Program using the coffee you normally use — different coffees and grind sizes can change flow rates.

• If you change grind size significantly, you may want to re-program doses to maintain consistency.

• Program with scale under cup to ensure you’re hitting your brew ratio, not just relying on volume in ml.

Example Setup

• Button 1: Single shot – 18 g in, 36 g out (1:2 ratio)

• Button 2: Double shot – 20 g in, 40 g out

• Button 3: Ristretto – shorter ratio (e.g. 20 g in, 28 g out)

• Button 4: Lungo – longer ratio (e.g. 20 g in, 50 g out)
