Breville espresso machine displays GRIND TOO FINE and extraction is slow or stalls.

Safety: Stop the shot if pressure spikes or flow stops to avoid overpressure.

Steps:

• Adjust the grinder to a coarser setting.
• Reduce the coffee dose to the recommended range for your basket size.
• Clean or replace the filter basket if holes are blocked.
• Remove and clean the shower screen and group head.

Resolution: Once resistance is reduced, the message should no longer appear. If it persists with reasonable grind and dose, inspect for internal blockages or a stuck OPV.
