C13 error appears during high-speed operation, and the motor stops unexpectedly.

Safety first: Unplug the appliance and wait for the blades to stop completely before opening.

• Reduce load: Remove some contents from the bowl and add more liquid if possible to reduce viscosity. Follow the maximum fill lines strictly.
• Inspect blades: Remove the blade set and check for bent, chipped, or heavily worn blades. Replace if damaged.
• Check for foreign objects: Ensure no hard objects (spoons, bones, pits) are trapped in the blades.
• Test at lower speed: After reducing load, run the machine at a lower speed and gradually increase. If C13 recurs with light loads, the motor or current sensing circuit may be faulty and require professional service.
