Any ideas why this might be so? Thanks in advance.
Wow...I don't believe I didn't see this post for an entire month. On the handle of the pressure cooker you will see a button. It might be purple, orange or turquoise, depending on which model you have. This is a lid lock which needs to be pushed toward the center of the lid. Unless the lid and pan handles are correctly lined up, this lock will not slip into place. Without engaging this feature, pressure will not build. Once pressure has started building, this cannot be disengaged. but wait, there's more...
Also on the handle, you will see a dial that can be turned to several icons. This is the operating valve. It features a steam release position, one or two pressure settings [depending on the model], and an unlock position that allows for the pressure regulator to be removed for cleaning. In order for pressure to build, the operating valve must be in pressure position.
Now, for the yellow button. This is another integrated safety feature. With the lid lock and the operating valve in position, as soon as pressure begins building, this button will pop up. This safety feature prevents the opening of the lid so long as there is any pressure at all in the cooker. However, contrary to Fagor's instructions, having the button pop up does not mean that you have reached full pressure. It means only that there is some pressure. The yellow button will not rise if either of the previous features have not been activated, or if the gasket is not correctly inserted.
You will know that full pressure has been reached when you can observe a steady stream of steam coming from the operating valve. This is your cue to reduce the heat to only what is needed to maintain pressure as indicated by a "whisper-puff" of steam at 5 or 6 second intervals. NOW is when you start your timer. At the end of the pressure cycle, use the appropriate pressure release method, according to the recipe.
While this might all sound like a lot of bother, it's actually not. Describing the various functions and how they are accomplished takes time, but the actual doing amounts to very little real time.
Cleaning the various components of the PC is also not really difficult or even annoying if you use the appliance correctly in the first place. Don't over fill, especially with foods that foam, and your cleaning will be kept to a minimum.
