MODEL-SPECIFIC QUICK ANSWER
Breville / Sage Infuser BES840 blinking lights and common signals
For the Infuser BES840, first make sure the steam/hot-water dial is at STANDBY before startup. If espresso pressure is low or flow is fast, adjust grind and dose gradually; if flow is slow, check the tank, dose, filter basket, and scale. Follow the manual’s cleaning and descaling steps, and do not open the case.
