I have a fairly new pressure cooker with different pressure settings. The problem is that it's not reliably generating pressure because the steam is always escaping through the safety nozzle.
If I want to use it I normally fill it with enough but not too much water, put it on the stovetop and put on high heat. The pressure cooker is set on the highest "pressure setting". The problem now is that it let's all steam escape and isn't generating any pressure.
The pressure cooking itself isn't (as far as I know) broken because it sometimes works but oftentimes doesn't.
Are there any tipps or tricks or should I just buy a new one?
