The Top Machine Coffee Gurus Are Doing Three Things
What Goes On Inside a Machine Coffee Maker?

Enjoying a cup of coffee at home is simple with a coffee maker. Many of the most well-known models come with a programmable clock, and even a built in grinder.

When you turn on the power the sensors control the heating element which circles the warming plate. It also includes an aluminum water tube that passes through it.

Cold-Water Tube

A machine coffeemaker takes the water you pour into it and transforms it into coffee. It does this by boiling the water, then passing it through a process that creates high pressure to force it through a capsule made of ground or soluble material. These machines use up to 15 bars of pressure, as opposed to coffee percolators that run at a mere one bar.

There is a reservoir in the bottom of your machine that looks like a bucket. It holds the water used to make your drink. This reservoir has a hole at the bottom. It connects to the tube in the heating element on one side and to an insulated tube running from the bottom of your machine up to the tap on the other.

When you start the machine the water from the reservoir is being pumped into the heating chamber. The thermostat then tells the machine to heat up. As the water heats up it expands and presses on a screen beneath a portafilter that has been filled with coffee and tamped down. This pressure causes the screen to pierce through the filter and let the espresso into your cup.

The espresso that comes out of your machine is a rich, flavorful beverage that can come with different levels of acidity based on the type of coffee you choose. If you notice that your espresso has a sour taste try changing to an alternative filter paper or a coarser ground coffee. If the issue persists then you must schedule an authorized service technician for an de-liming process to clean out your machine. This problem is usually caused by lime scale.

Hot-Water Tube

The white tube insulated in the base of your coffee maker is known as the hot-water tube. It transfers the hot water from the heating chamber to the faucet at the top of your coffee maker. This water saturates your grounds, bringing the flavors into the coffee pot you are waiting for.

Some coffee makers have an option to keep the water warm, so that it's ready when you get up. This is achieved by using a heater to produce some steam. The steam is then directed to the spout to ensure that your coffee stays warm until you are ready to pour it.

While it may seem as though coffee makers are complicated and expensive, the majority of models are quite easy to operate and come with only a few moving parts. A thorough cleaning and regular use should keep your machine in excellent condition for years to come.

Many coffee machines have a built-in coffee grinder that allows you to add the ground coffee and then lock the portafilter into place, and then flip the switch to begin coffee brewing. When the switch is turned the pump will begin to pressurize the water in the heating chamber until it's about 220 psi of pressure.

coffee machine for business of the biggest issues when making the perfect cup of coffee is having to refill the reservoir often. Some manufacturers have created coffee makers that can be connected directly to a common water line and allow you to eliminate the reservoir altogether. There are kits for those looking to make it their own. They can transform any machine into one that connects directly to a household water line. The process is a bit more complex and requires drilling holes into your machine to accommodate the adapter. This could weaken your coffee maker's construction and cause cracks around the areas that were drilled. For the best results, you should purchase a coffee maker made specifically to take an immediate line of water.

Resistive Heat Element

The heater is a piece of metal that has a specific type of resistance to electricity. It impedes the flow of electricity without stopping it completely. In addition, some energy is transformed into heat. This is what causes the heating of the water inside the boiler of your coffee maker.

The heating element is located on the left side of the machine's base. It resembles the filament of a lightbulb or the component of an electric toaster. It is comprised of an aluminum extrusion in two sections, with a tube that allows water to flow, and a resistive element. (Watch video here). The coiled wire is heated due to the resistance it has.

When you turn your coffee maker on the element starts heating up the aluminum water tube until it starts to boil. The bubbles will rise up through the white tube, and then be sprayed on your coffee grounds using the shower head. This water spray sucks up the essential oils of the ground coffee beans as it descends and also contains caffeine.

If your coffee maker is not release hot water, it's likely that the heating element or pressure switch thermostat is defective. Both are able to be tested using a multi meter using the continuity test. Connect one of the poles to the electrical connection and the other to the body of the flange and it should display the number lower than 1. If there is no reading then this indicates the switch or thermostat needs to be replaced.

The water pump or reservoir is a different part of your machine that may cause problems. It can get clogged up with lime and that is why you need to run a mixture of water and descaling solution through it.

Warming Plate

A warming plate is a metal surface that is heated that keeps coffee warm in a cup after it has been made. This coffee maker feature is very popular with people who love to eat out and is a great addition to any home kitchen. However, the warming plate can get rusty quickly and alter the taste of the coffee, making it essential to clean it frequently. The best method of cleaning the heating plate of a coffee maker is to use a mixture of water and oxalic acid.


Oxalic acid can be utilized as an effective cleaner to get rid of rust on pipes, sinks and gas stove burners. It can also be used to clean many other household items. It is an extremely effective method of cleaning the warming plate that is rusty in your coffee maker. It is available at most hardware stores. You should always be careful when using this product, as it can cause burns and other injuries if not handled correctly.

If you want to clean a coffee maker with rust heating plate first, ensure that the coffee maker has been unplugged. This will help prevent any damage caused by the heat generated by the cleaning products. It is also recommended to wear gloves made of rubber because the oxalic acid can be extremely rough on your skin.

Pour some white vinegar over the rusted portion of the heating plate. This will react chemically with the baking soda, and will dissolve the rust. Then you can use the rag or brush to scrub the area until it's clean. If your coffee maker is rusted, you may need to repeat the process several times to make sure it is completely clean. Make sure that the oxalic acid is completely evaporated before plugging your coffee maker back in and start using it again.

Aluminum Water Tube

When you turn on your machine, it will begin making the coffee for you. It might seem easy, but it's a long process to turn a few spoonfuls of coffee grounds and some hot water into a steaming hot beverage.

The cold water flows through an opening in the reservoir's bottom, and then into the aluminum tube that is beneath the resistive heating element. The aluminum water tube is heated, and when it reaches the boiling point, bubbles begin to appear that push water up the white tube at the center of the coffee maker.

The hot water sprays out of the top of the tube into the perforated disc that is known as the shower head. (Or basket in some machines). Here, the hot water is sprayed onto the coffee grounds, which absorbs the oil essence.

Then, the water flows down over the coffee before flowing back up through the filter to the pot. This is caused by the oscillating pressure created by the pump. The shearing force generated by the bubble's expanding and contracting boundaries separates ground coffee particles from the water, leaving behind an espresso-like, strong beverage.

Be aware that your machine is dependent on a variety of different components. They are all interconnected. Any one of these parts that break down or fail to function properly could affect the entire process, therefore, if you notice strange sounds or vibrations while your machine is working be sure to check for loose components. Loose components can create noise and weaken connections. This will cause further issues.
