Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fryer does not turn on. | Not plugged in; magnetic cord not properly attached; power outage. | Ensure the power cord is securely plugged into a working outlet and the magnetic connection to the fryer is firm. Check household circuit breaker. |
| Oil not heating up. | Temperature not set; heating element malfunction. | Verify the desired temperature is set on the digital display. If the issue persists, contact customer support. |
| Food is soggy/oily. | Oil temperature too low; overcrowding the basket; food too wet. | Ensure oil is at the correct temperature before adding food. Fry in smaller batches. Pat food dry before frying. |
| Excessive smoke. | Oil temperature too high; old/dirty oil; food burning in "Cool Zone". | Check temperature setting. Replace old oil. Clean the "Cool Zone" area regularly. |
| Magnetic power cord detaches easily. | This is a safety feature designed to prevent accidents. | Ensure the fryer is placed in a location where the cord is not easily snagged. Reattach firmly if it detaches. |
