E06 error appears; grinder does not run or stops shortly after starting, no ground coffee reaches the brew unit.

Safety: Unplug the coffee maker before accessing the grinder.

• Empty beans: Remove the bean hopper and empty all beans. Check for foreign objects (stones, plastic) that may have jammed the burrs.
• Adjust grind setting: Set the grinder to a coarser setting and try a cycle again. Very fine settings can overload the grinder.
• Clean grinder: If accessible, remove the upper burr and brush out old coffee residues and oils. Do not use water inside the grinder.
• Check grinder movement: Rotate the burr carrier gently by hand (if design allows). If it is seized, the grinder assembly may need replacement.
• Inspect wiring: Verify the grinder motor connector is firmly seated on the PCB and that no wires are pinched or broken.
