Fast blinking orange light; machine refuses to brew

User checks:

• Fill the water tank and ensure it is properly seated.
• Empty the drip tray and used capsule container; reinsert correctly.
• Open and close the lever firmly to ensure the capsule is correctly positioned.
• Run a rinse cycle without a capsule.

If the light continues to blink fast after these checks, inspect the internal flow system (pump, flow meter, hoses) as described in pump and flow error entries.
