Common problems with coffee machines, care and maintenance tips (2023)

How does a coffee maker work?

The 2 most popular types of coffee makers are drip and percolator. However, the principle behind most electric coffee makers is basically the same. The water chamber or reservoir is filled with cold water, which flows through a thin, flexible hose before reaching the heating chamber. The water in the heating chamber (usually aluminum) is heated to a temperature just below its boiling point. The increase in temperature leads to a corresponding increase in internal pressure within the heating chamber. As a result, hot water enters an insulated pipe that sends it to the sprinkler. The water coming out of the sprinkler falls directly onto the ground coffee in the basket. Then it goes through the filter. When the filter is saturated, the coffee slowly drips into the pot. One factor affecting this process is the energy generated by the heating element in the coffee maker. This element determines how quickly the water heats up, the amount of water that can be heated, as well as the temperature of the water exiting the sprinkler. The material of construction (copper or aluminium) of the heating chamber can also affect the process as its heat transfer ability is different.

Drip coffee makers use a series of switches and timers within the control panel to heat the water and drip it into the coffee basket. The hot coffee collects in the pot, which has a heating element on the underside to keep the coffee hot.

Sieves boil water in the bottom of the machine. Steam is produced, which pushes the hot water into a tube located in the center of the device. This water gets into the coffee basket and absorbs the aroma of the ground coffee. The bottom of the basket has fine holes that allow coffee to drip into the main compartment. The brewing system is controlled by a thermostat that shuts off when the right temperature is reached.

In recent years, new types of coffee makers have appeared on the market. Most machines have a built-in coffee grinder to ensure maximum convenience. Other coffee machines use thermal carafes that keep the drink at the right temperature. One-cup coffee makers are also very popular as they can brew other beverages such as hot chocolate and tea.

However, most modern electric coffee makers seem to suffer in some respects. They often do not pay attention to the fact that the coffee reaches the right temperature. During the fermentation process, the ideal water temperature should be 195 to 205 degrees Fahrenheit, but this is not always achieved. This could be due to issues related to the design of these machines or the use of hard water. Hard water can cause scale that reduces heat transfer to the heating chamber.

The main cause of this type of problem is any type of clog or water blockage. First check the hose in the coffee pot. If there are obstacles here or the hose is clogged, no water or other liquid can pass.

You may also need to check that the machine's thermostat and timer are working properly.

The coffee prepared in the machine is not heated.

If the coffee taken out of the machine does not seem to be getting hot enough, you need to check the heating element of the machine. Check the continuity of the warming switch on the machine with an electrical tester. Also, make sure the auto shut-off switch is in the correct position during the brewing process.

The coffee maker appears to be leaking

In certain cases, your coffee maker may leak hot water or excessive steam. This usually indicates a defective pipe inside the coffee machine. This situation can be easily resolved by making sure the pipes are properly installed and not loose.

My coffee pot is getting weak

A fairly common complaint is that the drink produced by the coffee maker weakens over time. In most cases, this problem is related to the plate spreading the water over the coffee basket. If it is cracked or broken, it must be replaced.

My coffee machine clicks

Sometimes a coffee maker makes a noise while it is running. Not only is this annoying, but it also seems to slow down the entire brewing cycle.

(Video) The Dirty Truth: Why You Need to Descale

If the coffee maker drips very slowly and you hear a loud noise, this could indicate that the machine is clogged. Dirt or mineral deposits in the water can clog the hoses in the brewer. In such cases, the coffee maker needs a thorough cleaning to ensure any clogs are completely removed.

This type of noise is fairly common with some compressed air coffee makers. Any dirt or debris that builds up in the brewing channels will cause noise and interrupt the brewing process. While a bit pricey, using bottled drinking water with your coffee maker might be a better option. This can prevent the accumulation of noise-causing minerals.

Coffee machine noises also occur when there are loose parts in the device. Rough treatment of the coffee machine can cause parts or connections inside the machine to come loose. Loose parts can not only cause noise, but also disrupt and prolong the brewing process. Check the different parts of the machine to make sure they fit together properly.

Coffee makers with aluminum tubing are particularly prone to buildup in hard water areas. This clicking sound increases as these tubes fill with solid deposits of calcium carbonate. If this situation is not resolved immediately, it can lead to more serious problems.

Most coffee makers have a one-way valve located in the opening of the bucket or in the aluminum tube. This valve is responsible for drawing cold water through the aluminum tube and discharging boiling water through the plastic tube. If dirt or other solid debris gets caught in the valve, a click may occur. The valve can be cleaned with a fine instrument or a toothpick.

Noise can also occur if the heating element of the is defectivecoffee machine🇧🇷 Usually this type of error is permanent and the device may need to be discarded.

Too low water level in the tank can also cause noise. This usually happens when the device has been on for a long time without being used. It can also be caused by holes in the heating coil.
