An espresso machine operates on a daily basis, and as with almost all devices that are frequently used, it is expected that sometime you will have a problem and need the care from you, or a specialist.
Below you will find the 10 most common problems that can affect the operation of your machine and how to deal with it!
1. The machine does not work
When the coffee machine does not operate, the possible causes are that the switch is not properly connected or there is a problem in the power supply. If you have checked that the switch is on (eg ON), then there may be a problem in the power supply to which the device is connected. First, make sure the power plug is securely plugged in – unplug and plug the power socket again. You can also check if the problem is electrical (wiring problems, power panel, etc.). If the problem persists, you should contact a qualified technician.
2. The machine does not produce coffee
When there is no coffee spill while the machine appears to be running, you should first check if the water supply is open. Otherwise, the passage or the valve may be clogged. In this case the machine needs a thorough cleaning, as the coffee residues and salts prevent the flow of water. The espresso machine, the band, the filters and in general all the accessories should be cleaned regularly. If the machine still does not produce coffee, then you should contact a qualified technician.
3. Coffee flows very slowly
The slow flow of coffee may be due to the very fine ground coffee, in which case the grinding rate in the mill should change. Otherwise the machine needs a good cleaning, as the residue blocks the flow of coffee. In particular, the machine group should be removed and cleaned as if the portafilter basket is dirty or the holes in the group tray are blocked, the flow of coffee is prevented. Finally, the pressure of the supplied water can affect the flow of coffee, so it should be checked by a technician if the water pressure has decreased.
4. Coffee flows very fast
Otherwise where the coffee flows too quickly, the mill should change its grinding rate for a finer effect as the coffee you use may be heavily ground. If the problem persists, a technician should check the pressure of the water supplied.
5. Coffee overflows from the portafilter
The overflow of coffee may be due to group wear or debris between the portafilter and the seal. If damaged, the edges of the portafilter basket or group gasket should be replaced. If there are residues causing the overflow, the machine group should be removed and cleaned.
6. Water comes out of the bottom of the machine
The most likely cause of water leaking from the base of the coffee maker is to have too much water in the liquid collector. After making sure that the machine is switched off and cold, release the liquid collector.
7. The nozzles do not release hot water / steam
The most likely reason is that the boiler has not been heated sufficiently. Wait a few minutes and try again. Otherwise, the hole in the nozzle is clogged. Clean it with a needle.
8. Coffee is not hot enough
The machine must be switched on a few minutes before the first brewing, so that the inside of the machine can reach the correct temperature. It may also be due to cold cups, many espresso machines feature a heating plate that keeps the cups warm, thereby enhancing the flavor and aroma of coffee.
9. Coffee is very nutritious
The cause can be hidden either in the wrong dosage or in the wrong choice of coffee blend. As for the former, you may need to increase your coffee dosage. Coffee is a natural product and its characteristics vary depending on the origin, the blend and the roasting. Another important factor is the degree of coffee grinding. To find the right dosage and the right grind, you may need to make several cups of coffee!
10. Coffee has an acidic taste
It is very likely that the machine has not been properly cleaned and therefore an acidic aftertaste to the coffee. It is advisable to clean the water tank frequently by using special non-chemical products that work without leaving chemical odors. Another possible cause may be improper storage of coffee, which means that it is stored for a long time in a warm, humid place and has broken down. You should store the coffee in a dry place at room temperature. Once you have opened the package, seal it well, or store it in an airtight container.
In general, maintenance and proper cleaning are essential for the proper functioning of an espresso machine.
