Machine shows A2 and stops brewing; pump can be heard but little or no water exits the coffee spout.

Safety first: Turn OFF and unplug the machine. Allow it to cool before working near the brew head.

Step 1 – Clean capsule area and piercing needles

• Open the capsule compartment and remove any used capsule.
• Inspect the capsule chamber for coffee residue or foil fragments; wipe with a damp cloth.
• Use a soft brush or a wooden toothpick to gently clean the piercing needles (top and bottom, depending on model). Do not bend or force the needles.
• Run a rinse cycle without a capsule to flush debris.

Step 2 – Clean coffee spout and internal outlet

• Remove the coffee spout/nozzle assembly if it is detachable.
• Soak the spout in warm water with mild detergent for 10–15 minutes, then rinse thoroughly.
• Use a small brush or pipe cleaner to clear any internal channels.
• Reinstall the spout and run several water-only cycles.

Step 3 – Descale the brew circuit

• Fill the tank with descaling solution as per Lavazza instructions.
• Run the descaling program or multiple hot-water extractions until the tank is empty.
• Let the solution sit in the machine for 10 minutes, then flush with at least one full tank of clean water.

Step 4 – Check overpressure valve (advanced)

• Unplug the machine and remove the top/side cover.
• Locate the overpressure valve near the pump outlet or thermoblock inlet (small plastic or brass valve with a return hose).
• Inspect for leaks, cracks, or obvious damage.
• If the valve is stuck closed or heavily scaled, replacement is recommended rather than cleaning.

When to seek service

• If A2 persists after thorough cleaning and descaling, the overpressure valve or internal brew block may be defective.
• Contact a service center if you are not comfortable replacing hydraulic components.
