Breville / Sage Dual Boiler BES920 / SES920 blinking lights and common signals
If BES920 shows FILL TANK while full, remove and fully reseat the tank and close its latch. A flashing power light during warm-up is normal; wait until the machine is ready. Check grind and dose for weak or slow shots, and follow the exact manual for cleaning and descaling.
