Water

A commercial espresso machine must be able to produce a high volume of espresso-based drinks efficiently. These machines are usually made of stainless steel, which is strong and resistant to cracks and scratches. These espresso machines are also easier to maintain and clean.

A high-quality machine must include an independent shut-off valve for the water pipe to prevent limescale build-up. This will ensure that any repairs are only limited to the affected components of the machine and won't affect the operation of the rest.

Test your water to ensure it's being treated correctly. Remineralize water that has been distilled by adding a few minerals. It can improve the taste and negate its erosive properties, but could also cause damage to certain machines. This is because the remineralized fluid will cause the boiler sensor to think that the machine is full when it is not. This could cause overheating and damage the machine.

Grinder

The grinder is a crucial element of the success of an espresso machine. It takes a raw, unground bean and turns it into finely ground coffee that can then be put into the filter basket for an excellent extraction.

Professional espresso machines of commercial grade typically have a built-in grinding unit that can be programmed to grind different sizes of drinks, providing consistent results each time. Super-automatic espresso machines go one step further by automating and programming the entire process from brewing to grinding to dispensing.

Although there are machines with higher pressures they generally require a more complicated group head design that can take on the higher pressures.

While some espresso machines for home machines advertise 15 or 18 bars of pressure in their machines, nine bars are generally considered to be the standard when it comes to creating consistently great brews. These machines with higher pressure tend to be cheaper and designed for home use.
