BARs (Barometric pressure) is the force your espresso machine applies to the grounds of your coffee while delivering high-pressure water. Your espresso machine is pushing heated water through the grounds of coffee at nine times Earth's current atmosphere pressure.
The pressure of your espresso machine is crucial because it allows the water to pass through the grounds of your coffee with the right speed and with the right intensity. If the pressure is too low, the dissolved oils and flavors aren't extracted properly. On the other hand, if the pressure is too high the water will be pushed through the coffee grounds too fast, and you'll end up with a weak and over-extracted cup of espresso.

Temperature
Temperature is among the most crucial factors in the perfect espresso shot. If the water is too hot, it can cause the coffee grounds to burn and create an over-extracted bitter coffee. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without scorching the grounds or causing excessive extraction.

Using a high-quality filter water is essential to your machine's overall health as well as the taste of the coffee it makes.
