- Adjust the temperature control settings if the slush isn’t freezing enough—try a colder setting.
- Check for ice buildup around the compressor or vents; clean as needed.
- Use the appropriate program for your beverage type and ensure the ingredients are cold enough before blending.
If issues persist, refer to the user manual or contact customer support for assistance to keep your summer drinks flowing smoothly.
