Error Code E3 means the overheat protection has activated.
FIX:
- Immediately turn off and unplug the air fryer.
- Allow it to cool completely to room temperature. This may take 30 minutes or more.
- After cooling, plug it back in and try turning it on.
IF THAT DIDN'T WORK: If the display continues to show E3 after a complete cool-down, the safety circuit may be faulty. Contact Cosori Customer Support. Do not attempt to use the air fryer.
HEADS UP: Ensure you leave 5 inches of space behind and above the air fryer for proper ventilation. Do not block the air inlet or outlet vents.
