8 Tips To Improve Your Machine Coffee Game
What Goes On Inside a Machine Coffee Maker?

Enjoying a cup of coffee at home is simple with a coffee machine. The most popular models come with a programmable timer and even an integrated grinder.

When you turn on the power the thermostat controls the heating element which circles a warming plate. It also has an aluminum water tube that runs through it.

Cold-Water Tube

A machine coffee maker is a device that takes the water you pour into it and transforms it into coffee. This is done by boiling water, then forcing it through a process that creates high pressure. These machines can operate up to 15 bar of pressure, as opposed to coffee percolators that only work at one bar.

The reservoir resembles an empty bucket that is located at the bottom of the machine and is the place where water is stored to make your beverage. This reservoir has a hole at the bottom that connects on one side to the tube inside the heating element and on the other, to an white tube that is insulated and extends from the bottom of the machine up to the faucet.

When you switch on the machine the water from the reservoir is being pumped into the heating chamber. The thermostat then tells the machine to warm up. As the water gets hotter it expands. This causes a screen to move beneath a portafilter which has been filled with espresso and was tamped. This pressure causes the screen to pierce through the filter and allow the espresso into your mug.

The espresso that emerges from your machine is a rich, flavorful beverage that can come with different levels of acidity based on the type of coffee you select. If you notice that your coffee has a sour taste Try changing to a different filter paper or a coarser ground coffee. If the issue continues then you must schedule an authorized service technician to perform the de-liming procedure to clear out your machine. The problem is usually caused by lime scale.

Hot-Water Tube

The white tube insulated in the base of your coffee maker is called the hot-water tube. It transfers hot water from the heating unit to the faucet that is on top of the coffee maker. The water is infused into the coffee grounds, carrying their flavors down to your waiting pot of coffee.

Some coffee makers have features that keep the water warm so that it's ready for you as soon as you wake up. This is done using a heater that produces a small amount steam. The steam is directed into the spout so that the coffee remains warm until you are ready to pour it.

Although it might appear as though the coffee maker is complex and expensive, the majority of models are quite easy to operate and come with only a few moving parts. Regular cleaning and use will keep your machine in top condition for many years to come.

Many coffee makers with built-in grinders allow the addition of ground coffee from a container, then lock the portafilter in place, and then flip the switch to begin the brewing process. The pump will pressurize the heated water until it reaches 220 psi pressure when the switch is turned.

One of the biggest frustrations when making the perfect cup of coffee is that you have to refill the reservoir frequently. Some manufacturers have created coffee machines that can be connected directly to the water line. This lets you bypass the reservoir. If you're a DIYer there are kits that can transform any machine into an espresso maker that has a water line connection. This process is a little more complex and requires drilling holes in your machine to accommodate an adapter. This could weaken your coffee maker's construction and cause cracks in the areas where you've drilled. It is recommended that you purchase a coffee maker that is designed to take a direct water line to get the best results.

Resistive Heat Element

The heater is a piece of metal that has a special kind of electrical resistance. It blocks current flow, but without stopping it completely and some of the energy resisting it is turned into heat. This is how the boiler of your coffee maker is heating the water.

The heating element is located on the left side of the base of your machine and it resembles a light bulb filament or the component in your electric toaster. It is made up of an aluminum extrusion having two sections, a tube for water to flow through and the resistive heating element itself (Check video here). This coiled wire heats up due to the resistance it has.

When you turn your coffee maker on the element starts heating up the aluminum water tube until it begins to boil. The bubbles will then rise through the white tube, and then be sprayed on your coffee grounds using the shower head. The water sprayed gets the essential oil essence of the ground coffee beans on its way down and it also contains caffeine.

If your coffee maker is not releasing hot water, it's most likely that the heating element or pressure switch thermostat is faulty. You can test both with 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 show the number lower than 1. If the reading isn't there, then you have to change the thermostat or switch.

The reservoir, or water pump, is a different part of your machine that can cause problems. It can become clogged with lime, so you will need to run water and descaling agents through it.

Warming Plate

A warming plate is a metal surface that is heated that keeps the coffee warm in a cup after it has been prepared. This coffee maker feature is very popular with diner coffee lovers and is a great addition to any home kitchen. However the warming plate could get rusty quickly and sour the taste of the coffee, which makes it important to clean it frequently. The best way to clean the heating plate of a coffee maker is to use a mixture of water and oxalic acid.

Oxalic acid is an effective cleaning agent that can be used to get rid of the rust from sinks, pipes gas stove burners and a variety of other household items. You can buy this product at a variety of hardware stores. It is a great method to clean the rusty warming plates in your coffee makers. Be cautious when using this product as it can cause burns and other injuries if handled properly.

If you're cleaning the heating plate, first make sure that the coffee maker is disconnected. This will avoid any damage that could be caused by the heat from the cleaning products. You should also wear gloves made of rubber, as the oxalic acid can be very harsh on your skin.

Pour some white vinegar on the rusted area of the heating plate. The chemical reaction will dissolve the rust. Finally clean the area using the rag or brush until it is completely clean. If your coffee maker is very rusted, you may need to repeat the process several times until it is completely clean. Make sure you wait until the oxalic acids have completely evaporated before plugging the coffee maker in again.


Aluminum Water Tube

The machine will start making coffee the moment you start it up. It seems like something that is easy enough, but there's lots going on there to turn a few scoops of grounds and a few cups of water into a steaming hot drink.

First, the cold water flows through an opening in the reservoir's bottom, and then into the aluminum tube beneath the resistive heating element. Then the aluminum water tube begins to heat up, and when it gets to its boiling point, bubbles begin to form that push the water into the white tube that is that is located in the middle of your coffee maker.

The hot water sprays through the top of the tube, transforming into the perforated disc that is known as the shower head. (Or basket in certain machines). The hot water is poured over the ground coffee and absorbs the oil's essence as it does so.

Then the water runs through the coffee, then back up through the filter to your pot. The pump's oscillating pressure is the reason for this. The expanding and contracting of the bubble boundaries exerts an elongation force that separates the coffee particles from the water leaving a strong espresso-like beverage left behind.

Be aware that your machine is dependent on a variety of different components. They are all interconnected. If you notice strange sounds or feel vibrations this could be due to a loose part. Loose parts can cause noise and may weaken connections, which could lead to additional problems.
