For over 30 years, manufacturers have worked tirelessly to improve their coffee maker designs. And through this, more straightforward coffee brewers now exist, enabling you to have your favorite brew at the press of a button. Nonetheless, most people still wonder, how does a coffee maker work?
A coffee maker works by allowing cold water from the reservoir to get to the heating element via the one-way valve. The heated water rises through the white tube and evenly drips on the coffee grounds. Brewing occurs, and the resulting coffee drips into the waiting coffee pot.
Just like you understood how a siphon coffee maker works, this article will help you understand how a coffee maker works and the different types of coffee makers you can find in the market. Let’s explore.

How Does a Coffee Maker Work?
A modern coffee maker is an effortless device. That means you can easily use your brewer without any special training.
Before I take you through how the coffee maker works, let’s first look at what is inside a coffee maker.
1. Water Reservoir
The reservoir is the most significant component of a coffee maker. Its work is to hold the water you place into your coffee machine for brewing.
Coffee maker reservoirs vary in size, some having the ability to hold more water than others. But no matter the size, they still perform the same function of keeping water.
2. The Faucet
This tiny showerhead above the coffee grounds sprays the water transferred through the hot water tube above the coffee. The faucet also helps with the saturation of coffee grounds to ensure you get a pleasant cup.
3. Hot-water Tube
This insulated tube runs from the lower part of the machine to the faucet at the top. It is always white and enables heated water to push through to the faucet for dripping on the coffee grounds.
4. Drip Area
The drip area is a little piece of plastic containing holes in it. It regulates the rate of the water dripping onto the coffee grounds.
5. The Heating Element of a Coffee Maker
This’s a coiled wire comparable to the filament of the component in an electric toaster that turns hot when you run electricity. The coil is implanted in a plaster making it more rugged.
The heating element performs two operations;
- It heats the water when you put it in a coffee maker.
- Keeps the coffee warm once made.
Other coffee maker components include;
- Coldwater Tube
- Power Cord Connection
- One-Way Valve
Now, how exactly does a coffee maker work?
1. It all begins in the reservoir when you pour in cold water. The water flows through the hole entering the orange tube.
2. After that, water goes through a one-way valve and gets into the aluminum tube in the heating element, thanks to gravity.
3. The resistive heating element then heats the aluminum tube, eventually boiling the water in the aluminum tube.
4. As the water boils, the water bubbles rise through the white tube to the faucet
5. The faucet sprinkles the hot water over the coffee grounds evenly.
6. The boiling water moves through the ground coffee beans, collecting their oil essence down into the coffee pot. Those coffee oils obtained during the roasting process are known as caffeoyl.
7. You can get your cup of coffee from the pot.
Types of Coffee Makers
Here are some of the coffee maker types available in the market today:
1. Drip Coffee Makers
Drip coffee makers are efficient and easy to use when making coffee. Depending on the model, they can brew up to 14cups of coffee.
You start by incorporating ground coffee into a filter and then water into the reservoir. Water boils up and passes through the beans via what resembles a showerhead.
The brewed coffee then flows into a glass carafe on top of the hot plate, which keeps the coffee warm.
Drip coffee makers are best for families, traditionalists, and entertainment.
- The warming plate may burn coffee if left there for a long time.
- It’s limited to brewing coffee.
2. Espresso Machines
Even though espresso machines are pretty expensive, their rich, delicious brews are unmatchable. The brewing machine mainly uses dark roasted coffee beans with a fine grind.
Its coffee concentration is higher than drip coffee and is often served in a smaller cup.
You can make espresso using a semi-automatic, automatic, manual, or super-automatic machine.
Espresso machines work by heating water and enabling it to flow through pressed grounds at high pressure.
- Produces a great cup of espresso.
- It mostly comes with a milk frother.
- You can use espresso as a base for other coffee drinks like cappuccinos and lattes.
- Requires labor
3. Pour-over Coffee Maker
Pour-over coffee maker brews coffee gently, and you can use it over a large carafe or single mug of coffee.
You need to insert medium-coarse grounds into a cone-shaped funnel, including a filter. Then include hot water into the beans in batches. As the water penetrates through the coffee grounds, it empties into a carafe, producing a rich cup of coffee.
This brewer is best for single-cup lovers.
- It only needs hot water and a paper filter.
- The brewer makes a gentle full-bodied cup of coffee.
- It takes a little longer to brew than other methods.
4. French Press Coffee Maker
This coffee maker works by slowly soaking coffee grounds in just-boiled water to make a rich and satisfying cup of coffee. The longer you soak the coffee, the more pleasant the flavor. However, four minutes is the recommended time.
When using the French press coffee maker, you combine coarse to medium-course coffee grounds with boiled water. Afterward, allow the mixture to soak in an enclosed carafe. After a few minutes, you gently push down the plunger to move the grounds to the carafe’s base.
The French press coffee maker is best for coffee lovers who love the taste of rich and satisfying coffee.
- Brewed coffee is pleasant and flavorful.
- Soaking time can be easily regulated.
- You can control extraction since coffee brews just below boiling.
- Coffee becomes cold quickly.
- Glass pots are delicate.
