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

Safety first: Unplug the cooker before cleaning the control panel.

• Check for child lock: Some KitchenAid models have a control lock. Look for a lock icon and hold the designated button (often Start/Cancel or a lock symbol) for 3–5 seconds to toggle.
• Panel cleaning: Wipe the control panel with a slightly damp cloth to remove grease or residue that may interfere with touch sensors. Dry thoroughly.
• Test other buttons: If only the Start button fails while others respond, the keypad may be damaged and require replacement.
• Power reset: Unplug for 10 minutes, then plug back in and try again.
• When to call a technician: Persistent non-response indicates a faulty keypad or control board that should be replaced by a professional.
