Fissler Pressure Cooker Red Button Doesn't Work And Leaking Problem

We purchased a Fissler pressure cooker last year before getting married. Unfortunately, we never had the chance to use it until recently, and we're quite disappointed to discover a leakage issue. Even when we use minimal water, the red button doesn't rise, and the cooker leaks water everywhere, creating a mess and making the stovetop oily. It's disheartening to experience such problems, especially considering the trust we placed in the Fissler brand.surely expected better quality and performance from a brand that has earned our confidence, but look at this.
