Pump runs loudly but little or no water comes from the group head.

Safety first: Keep the machine unplugged when disconnecting hoses. Avoid running the pump dry for long periods.

Steps:

• Refill and reseat tank: Ensure the water tank is full and properly installed.
• Prime the system: Open the steam/hot water valve and run a hot water cycle for 30–60 seconds to purge air.
• Descale: Run a full descaling cycle to clear internal scale from the boiler and flow meter.
• Check hoses: If accessible, inspect inlet and outlet hoses for kinks or crushing and correct as needed.

Note: Persistent low flow after descaling may indicate a failing pump or blocked internal components that require professional service.
