Multicooker powers on but will not start any program when Start is pressed.

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

• Check child lock: Some Philips models have a child lock. Look for a lock icon on the display and refer to the manual to disable it (often by holding a specific button combination).
• Clean and dry panel: Wipe the control panel with a dry cloth. If it was recently cleaned with liquid, allow it to dry for several hours before use.
• Test other buttons: Check if other buttons respond. If only Start is unresponsive, the Start key contact may be worn.
• Service panel: A non-responsive Start button or touch sensor usually requires replacement of the control panel assembly or keypad membrane by a technician.
