Yeah, this one's common. It's usually not broken. White smoke is normal when you're cooking greasy ingredients like fatty meats or frozen fries with a lot of oil coating.
Fix: It doesn't affect the appliance or the food. Just let it run. The smoke should subside. Make sure you're not covering the air inlet or outlet on the unit while it's operating, as that can cause overheating.
If that didn't work: If you see dark smoke, that's different. Immediately unplug the appliance. Wait for the smoke to stop before removing the basket. Dark smoke means something is burning, likely food debris. After it cools, clean the heating element with the provided brush to remove any debris.
Heads up: Never fill the basket with oil. That's a fire hazard. The smoke from greasy food is just the existing oil in the ingredients heating up.
