7. Troubleshooting
If you encounter issues with your Ranvaira Slushie Machine, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not turn on. | Not plugged in; power outlet issue; machine malfunction. | Ensure the power cord is securely plugged into a working outlet. Check the circuit breaker. If the issue persists, contact customer support. |
