How Does Coffee Maker Work

All coffee makers work with the same basic process of moving the water through coffee filters and into your cup. With some differences that come with the coffee maker, you have at your home. Here we are going to look in detail at how the Drip Coffee maker works.

Drip Coffee Makers

The coffee makers commonly present at home are Drip Coffee Maker. It is a simple and straightforward device. Manufacturers have spent more than 30 years developing this simple design that is easy to use and handle.

Components of Drip Coffee Maker

When you open your Drip Coffee maker, you will find a reservoir, shower head, drip area, and heating elements, and much more. You can also have a look at the best semi-automatic espresso machines.

Let us discuss all the components to understand better how Drip Coffee Maker works.


A reservoir is a bucket-like container that contains the water you put in your coffee maker to make your cup of coffee. It has a hole at its bottom that connects the white tube to the drip area. The white tube is responsible for carrying the hot water to the drip area.

Moreover, this white tube also helps you in cleaning your machine with cleaning solutions. Some coffee makers also have the option to remove it.

Shower Head

When the white tube carries the hot water from the reservoir, it is received by Shower Head. It is responsible to spray hot water onto the coffee grounds evenly.

Drip Area

The drip Area is a plastic disc with holes in it that separates the faucet from the coffee. It is responsible for controlling the rate of water falling onto the coffee grounds.

Heating Element

The heating element is a simple coiled wire made of aluminum. It is quite similar to the filament present inside the bulb. It is responsible for transferring electrical energy into heat energy. That’s why when electricity runs through it, it gets hot. This way it gets its job done by:

  • First, when electricity runs through it, it heats the water.
  • Second, when coffee is made, it keeps it warm.


The heating element is insulated with grease that serves the purpose of insulation to transfer heat efficiently. This is the same kind of grease you find on power supplies that can dissipate heat.

The One Way Valve 

This one-way valve is usually present either in the reservoir or aluminium heating tube. The main purpose of this valve is to make sure water is moving in the right direction. It lets the cold water into the aluminium tube but moves the hot water to flow up the white tube.


Just like all modern appliances, the Drip Coffee Maker also has an on and off switch. It provides electricity to the heating element when it is switched on. This will heat the heating element, boils the water and the bubbles will rise to the white tube.


The Drip Coffee Maker has a sensor and fuse to main a steady flow of electricity to the appliance. It keeps the heating element from overheating.

It performs its function by cutting off the electricity temporarily when it detects the element is heated up. Once cooled down, it again allows the electricity to turn. This way it maintains the temperature of the Drip Coffee Maker to work properly.

How Drip Coffee Maker Works

We have discussed the components of a drip coffee maker in detail. Now it’s time to reveal the magic of how a drip coffee maker works.

I know the way you see coffee making is different. Pour in the water, scoop in just the right amount of coffee, place the pot in its place and wait. Tada, your coffee is ready. But in reality, the journey is a bit different. Let us see how:

  1. You pour in the cold water in the reservoir to let it start its journey towards your coffee making.
  2. Remember the hole at the bottom of the reservoir. The water moves down through that hole into the white tube that is connected to the hole of the reservoir.
  3. The water then moves into the aluminium tube through the one-way valve. It is now beneath the heating element.
  4. When you switch on the power, the heating element will get heated and boils the water present in the aluminium tube.
  5. The boiling water creates bubbles that push the hot water up through the tube into the faucet.
  6. The showerhead then sprays the hot water evenly onto the coffee grounds.
  7. The sprayed hot water saturates the coffee ground and takes its flavor and aroma with it down in the pot.
  8. And this way your coffee is ready.

How To Care For Coffee Maker

Sometimes your coffee maker doesn’t work properly. That means you have taken it for granted and have not taken care of it. You have to clean your coffee maker regularly to not get it clogged and enjoy the freshness of the coffee.

Here are some simple steps listed to help you clean your coffee maker.

Check if the drain hole is clogged

The water enters the machine through the drain hole at the bottom of the reservoir. To make sure it is not clogged, it should be checked. And if it’s clogged, a small wire or a toothpick can do the trick.

Clean your coffee maker with vinegar 

You can add a mixture of vinegar and water and run the cycle as normal. Once done, discard the water. And run it again with clean filtered water this time. This will thoroughly clean your coffee maker.

Make sure the valve is clean 

To check the valve, the base of the coffee maker has to be removed. Before cleaning the valve, always unplug the coffee maker. Clean it with warm water and detergent. This should clean the valve completely.

Clean the water spout

The opening through which coffee comes out should be cleaned all the time

In a flash, it can be said that you put water in the reservoir. From there it is drained into the white tube underneath the heating element. The heating element helps to boil the water, which forms bubbles and moves up through the coffee maker and is sprinkled onto the coffee grounds. And you get your coffee fully saturated with its flavour and aroma.
