Display shows E08 and the grinder does not run or stops quickly during grinding.

Safety first: Turn off and unplug the machine. Do not insert fingers or tools into the grinder while it is connected to power.

Step-by-step:

• 1. Empty bean hopper: Remove all beans from the hopper. Use a vacuum cleaner with a narrow nozzle to remove loose grounds from the hopper and grinder inlet.
• 2. Check for foreign objects: Inspect the hopper and visible grinder inlet for stones, wood fragments, or other contaminants that may have come with the beans.
• 3. Adjust grind setting coarser: Set the grinder to a slightly coarser setting to reduce load on the motor. Only adjust while the grinder is running (if the manual specifies this) to avoid damaging the adjustment mechanism.
• 4. Run a cleaning cycle: Some Siemens models support grinder cleaning tablets. Follow the manual to run a grinder cleaning program to remove oily residues.
• 5. Advanced cleaning: If accessible, remove the top burr carrier according to the service instructions and brush out compacted coffee from the ceramic burrs. Do not wash burrs with water unless specified by Siemens.
• 6. Professional repair: If E08 persists, the grinder motor or its driver circuit may be defective and should be replaced by a Siemens technician.
