Possible Causes

Transient firmware glitch, Loose internal connector, Faulty control panel, Power surge

Safety first: Unplug the cooker before any internal inspection.

Reset the unit: Unplug for at least 10 minutes, then plug back in. This can clear minor firmware glitches.
Check power source: Plug directly into a wall outlet (no extension cord). Verify outlet voltage is stable.
Button test: Press each button on the control panel to ensure none are stuck or unresponsive.
Advanced: If the error appears immediately on power-up, the control panel board or main board may be defective and require replacement.
