A coffee maker is a kitchen appliance used to brew coffee without having to boil water in a separate container.
Before we dive into how a coffee maker works, we must look at different types of coffee makers. Each type of coffee machine works differently. Therefore, we must look at each type differently.
There are various types of coffee machines that cater to different needs. So, let’s take a look at each one to know for what purpose it has been used.
Drip Coffee maker drip
This coffee maker is an elective machine that works at a lightning-fast pace. It has the ability to generate one to four cups of coffee quickly. Plus, it proves to be more liable and durable than a conventional coffee maker. It is also easy to use, making it favorable for those who like an easy-to-use appliance.
French Press Coffee Maker

Espresso Coffee maker
The coffee maker is a bit expensive but generates intrinsic flavored coffee. If you are a die heart fan of espresso, get the machine to give great espresso coffee. Besides being expensive, it is also a labor-intensive machine, making it difficult for a household user to run it. Due to its difficult-to-use procedure, we will look at how an espresso coffee maker works.

So, in this article, we will look inside a La Marzocco espresso coffee maker so you can understand exactly what happens when you make a coffee.

It basically has three external features to introduce you to an espresso machine. The first feature marked in the above picture is called a Group head. The group head is where the water flows through the coffee.

The second feature we can see in the above picture is the steam arm. It is used for heating and frothing milk.

And the last one is the hot water spout or nozzle. So what is it for if you can imagine? You right! Hot water. Americans famously use it for making tea.
When we combine those three functions, you can make such a wonderful hot coffee.
You may have seen them many times in your favorite coffee shops. But we will show you in detail how this machine work, what is going on inside it, and give you the perfect coffee.
Drinks like the Cappuccino, latte, and Americano, all start with a shot of espresso. The ground coffee that we place in a device is called a portafilter. Just check the portafilter photo below.
And when you pull a shot of espresso, the water is forced through it at the ideal temperature, producing a perfect coffee. But to get it perfect, you need to get all the settings just right.
If you have a coffee machine with a dual boiler system, you can have your hot water and steam in 1 boiler at a higher temperature. Then you brew the boiler.

Under the hood of a professional machine, it is easy to see these two large separate boilers perfect for when you need to make much coffee in a commercial shop. And a machine that is designed for a home like this linear mini works in the same way, but the brew boiler is contained directly above the group head.

The water is first heated to around 65 degrees Celsius by passing it through the heat exchanger from inside the steam builder. Then it rapidly heated between 90 and 96 degrees Celsius through a coiled pipe, giving you the perfect temperature for your espresso at home.
A lower temperature would cause the flavor to be too acidic, while too high means your coffee will end up tasting bitter. And on the domestic machine, you can adjust it to your preferred temperature.
You also need the water at a particular pressure to control the flow rate through the ground coffee. For espresso, there can be around 9 bars. Now the water is held at a press in the boiler. These have 3mm thick walls of surgical grade stainless steel put together with some pretty serious welding.
Every machine they make here is built by hand and rigorously checked multiple times before it is allowed to leave the factory and is released out into the wild. The technicians ensure the brew boiler does not lose temperature or pressure, ensuring consistently good coffee.
Espresso is excellent, especially as a little pick me up. But to make a drink like a cappuccino or a latte. You need steamed milk, and that is where these machines’ genius has a 2nd boiler comes in.
In the old days, all machines used the same boiler for espresso and steam when in fact, you wanted two different temperatures, so nothing was over perfect.
On this machine, the steam boiler is set at around 123 degrees Celsius and 1.5 bars of pressure. So the milk can be steamed perfectly and efficiently.
When you turn this, the water vapor is forced through into the steam arm and out of 4 little tiny holes in the bottom, perfect for giving that nice silky textured milk.
