Display shows ADD FOOD and beeps during preheat; user thinks it is an error.

Note: This is a normal status message on many Instant air fryers, not an error code.

• Follow prompt: When ADD FOOD appears, open the basket, place the food inside, and close the basket to continue cooking.
• Disable preheat (if desired): Some models allow disabling preheat in the settings menu. Refer to your user manual to change this behavior.
• Check manual: Confirm the meaning of display messages in the Instant air fryer manual to distinguish between prompts and errors.
