Breville drip coffee maker shows FILL TANK and will not start a brew cycle.

Safety: Unplug before removing the tank if you will be inspecting internal parts.

Steps:

• Fill the tank to the MAX line and ensure it is fully seated.
• Check and clean the inlet filter screen at the bottom of the tank.
• Remove and reseat the tank several times to purge air from the inlet.
• If the message persists, inspect the tank presence switch or magnet sensor inside the machine for proper operation.

Resolution: Replace the tank if the outlet valve or seal is damaged. Replace the tank presence switch or sensor if it fails continuity tests.
