The button-like thing between the main pressure regulator and the handle is a safety release valve. The valve has a small o-ring that will seat on the lid when the cooker is closed, locked, and under pressure. Examine the o-ring to make sure it is clean, and smooth with no damage to it. It should be firm but not hard and dried out. Examine the lid area around the valve to make sure that it is clean and smooth, if not clean any food residue. I am not sure if this next sentence applies to your model however you will be able to tell by looking at the valve. In the exact center of this valve, looking at it from the bottom, there will be a ball bearing that is spring loaded to provide overpressure relief. You will only be able to see part of the bearing through a hole maybe 1/16 or 1/8 inch in diameter in the middle of the relief valve. If there is food there try Guy's suggestion of putting vinegar in the hole to dissolve the food. If there is no food you can take a ball point pen and press on the ball to make sure it moves freely. It probably will. The valve itself will probably not seat i.e. the o-ring against the lid unless the lock is in place, i.e. the latch on top of the lid is pressed forward. You can check this by turning the lid upside down and looking at the catch that moves forward to lock the lid in place. On the side of this, probably the right side as you are looking at it, is a small catch. You can disengage this by pressing it to the center of the handle and pushing the lock in as though locking the lid in place. You might have to use something such as a knife, fork or something like that to move the catch. With the lid lock moved forward the safety release valve should be able to move freely and seat on the lid top with the o-ring contacting the the lid. If it does not you have some food in this section of the safety release valve. Follow Guy's suggestions to remove. With the lid locked, but not on the cooker, you might be able to check the seating of the valve by attempting to blow through it
by turning the lid upside down and blowing through the valve. You will have to seal the valve with your lips to tell.

Make sure that the lid where the gasket goes is clean and that the gasket itself is clean.

You might be able to confirm that the safety release valve is causing the problem by putting some water into the cooker, close and lock the cooker and attempt to bring to pressure. Examine around the lid to see if steam is coming out of the gasket. You can also do this by taking a knife with a wide blade, cooling it in some water and holding it under the handle by the pot and see if steam condenses on the knife blade. Steam condensing would indicate a gasket problem.

Good luck
