Troubleshooting
- Difficulty Cleaning Nooks: While the included brush is effective for most areas, some users report small food particles getting stuck in hard-to-reach plastic grooves. For stubborn residues, try soaking the unit in warm, soapy water before brushing, or use a thin, stiff brush.
- Blade Sharpness: The blade is integrated and not designed to be removed or sharpened by the user. If the blade's performance significantly degrades over time, consider contacting customer support for assistance.
- Vegetables Not Fitting: The slicer is designed for a wide range of vegetables. If a vegetable is too large for the feeder, it may need to be cut into smaller, manageable pieces before processing.
