Why does the lid of my Philips All-In-One Cooker take so long to open?

After pressing the button to open the lid of your Philips All-In-One Cooker, it's normal for there to be a slight delay before the lid opens. This is due to the tight seal that's created when the cooker is pressurized.

When the cooking process is complete and Lid unlocked is illuminated, press the lid open button and gently lift the lid using the handle. Be mindful that steam may be released as the lid opens.
