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

Safety first: Ensure the cooker is cool and unplugged before cleaning or pressing hard on controls.

• Check lid status: Close the lid firmly until you hear a click. Some models require the lid to be locked even for non-pressure modes.
• Look for lock icons: If your display shows a lock symbol, consult the manual to disable child lock or key lock mode.
• Test other buttons: See if other keys respond (change mode, adjust time). If only Start is unresponsive, the Start key contact may be faulty.
• Clean the panel: Wipe the control panel with a slightly damp cloth and dry. Do not use excessive water or cleaners.
• Power reset: Unplug for a few minutes, then plug back in and try again. If still no response, the keypad or control board likely needs replacement.
