Multicooker powers on but will not start any cooking program; pressing Start does nothing or beeps only.

Safety first: Ensure the cooker is on a stable, level surface.

• Verify basic conditions: Confirm the inner pot is installed, the lid is fully closed and locked, and a valid program and time (if applicable) are selected.
• Check display messages: Look for icons or warnings indicating lid open, missing pot, or other conditions. Resolve those first.
• Test Start button: Press Start firmly. If other buttons respond but Start does not, the keypad contact may be worn.
• Power reset: Unplug for 10 minutes, then retry. If the issue persists across all programs, the control panel or PCB may need replacement.
