preinfusion la marzocco linea av with key?
Anyone know the trick? Having trouble switching on preinfusion with latest 1 Group linea av, this model has masterkey for programming control? Tried holding swirl button 2 secs, switch off, then on.....nada
Switch machine to off. Hold button 1 (short coffee) on group 1; turn machine on and ensure LED is lit over spiral button; switch machine off. Switch on touching no buttons. Preinfusion now enabled. Use button 2 (normalé) group 1 and same procedure to disable.
And how does it work the preinfussion after the key? Can it be programmed?
i'm thinking of buying this machine for a small restaurant.
