Machine off - Switch on the machine while holding down the "Menu" button, until all the leds are flashing on/off: it's the "maintenance" mode. - Press 80 - Press the "Mono start" button several times until you see "purge: xxxx" - Press "2783" in order to reset the purge counter. You will see: "purge:0000" - Press the "Stop" button. - Press "99" to exit the maintenance mode. This may or may not work but it's worth a shot.
