Pressure
If you're serious about your coffee and know that the pressure of your espresso maker is a crucial factor in how your drinks are made. You may be looking for a thick layer of crema or the right balance of flavor and acidity, the pressure of your espresso maker is the key to brewing great espresso.
BARs (Barometric pressure) is the force your espresso machine exerts on grounds of the coffee while delivering high-pressure water. The espresso machine is pushing hot water through the grounds of the coffee at a rate nine times the current atmospheric pressure.
The pressure of the espresso machine is crucial because it allows 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 won't be properly extracted. If the pressure is too low, the dissolved oils and flavors will not be extracted correctly.
You can control the pressure of your espresso maker by changing the screw on the espresso maker. Commercial machines and top-end home machines come with the rotary pumps that have adjustable pressure. For the cheaper home machines that use an oscillating pump, changing the pressure is impossible without involving DIY hacks. However, companies such as Cafflano are developing technology that utilizes Pascal's Principle to create maintained pressure inside the portafilter throughout the fermentation process.
Temperature
The temperature is one of the most crucial factors to the perfect espresso shot. If the water is too hot, it will scorch the coffee grounds and produce an over-extracted bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all desired coffee flavors without scorching the grounds or excessively extracting.
The best espresso machines have a thermoblock or thermocoil which heats the water and keeps it at a stable temperature throughout the whole extraction process.

Some machines come with an analog gauge that is cool and helps you develop your brewing capabilities. Ideally, you should get around nine bars of pressure and keep this throughout the entire brewing process. This machine is close to getting to that point.
A built-in burr mill is another great feature. This feature is perfect for beginners since it eliminates having to buy an additional grinder. The grinder is a conical stainless steel device with 18 settings ranging from "coarse" to "fine."
The grinder isn't as powerful as a stand-alone device, but it's a good start and will have you on the path to brewing quality espresso shots. It's easy to clean, and you can pause it during the grinding process to avoid creating a mountain of ground that will fall onto your portafilter on its way to grinding.

This is best achieved using a water filter system which does away with chlorine and then adds back a small amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will create an ideal balance of hardness and alkalinity and will help avoid the necessity of decalcifying your equipment.
Using high-quality filtered water is vital for your machine's long-term health and the flavor of the coffee it makes. Based on the usage and the hardness of your machine, you should make use of descaling products on a regular schedule. These products come in powder, liquid and tab forms and can be found in many hardware stores.
