Coffee and coffee machines have become part of our life – many can no longer imagine the morning without a sip of an invigorating drink. Therefore, a breakdown of the coffee machine can seriously ruin the mood. Do not rush to get upset and save money to call the master. It is quite possible that the cause of the breakdown can be eliminated by yourself.
First of all, it is worth referring to the instructions for the operation of the coffee machine. If there is some kind of error message on the display, there are probably recommendations in the instructions. However, a little more effort is needed to fix some breakdowns. How to deal with the most common problems is below.
The horn is leaking
The horn of the coffee machine breaks down more often than others. Leaking from under it is one of the most common malfunctions of coffee machines. There are enough reasons: for example, high pressure, frequent mechanical stress and coffee falling under the horn. The first signs of breakage are easy to spot. Drops of water begin to flow down the horn and disappear when it is tightened more strongly. If you do not pay attention to this symptom in time, the water will soon flow in whole trickles. In this case, no tightening of the horn will help.
The first thing to do when the first symptoms appear is to make sure the cone is clean. Then you need to clean the cone seal with a small amount of dish detergent. A sponge or microfiber cloth is suitable for this.
If that doesn’t work, order a new horn seal for your coffee maker. It costs 300-600 rubles, depending on the model.
Replacing the seal on most machines is not a problem. Chances are, you can handle it yourself. It is necessary to remove the mesh holding the seal (usually it is fixed with one screw in the center), then remove the part itself. Clean the installation site, then carefully install the new seal and screw the mesh back.
From under the car flows
Leaking from under the coffee machine is a more serious problem, but in most cases it can also be fixed by yourself. First, you need to determine the place where the leak was formed. Disconnect the appliance from the power supply, remove the cover and locate the leak. Most often, either one of the fittings (connections) of the water hoses or the boiler gives a leak. In the latter case, the breakage can be seen by the characteristic limescale in the place of leakage.
In addition, a boiler leak is often accompanied by other symptoms – error messages, a short circuit (knocks out plugs), or the cessation of water heating.
If the boiler is intact and dry, check all fittings for drips. If there are several “suspicious” places, plug in the machine and start it up with the cover removed. Be careful – parts of the machine may be energized. Do not touch the “insides” of the machine during operation. Once you have identified the leak, remove the hose from the connection. Usually the hose is secured with a steel or plastic bracket – it should be carefully removed with a screwdriver.
Inspect the fitting itself and the tip of the hose. If there is a seal at the end of the hose, examine it. Typically, a leak is caused by a cracked fitting, damaged seal, or damaged hose tip.
The damaged end of the hose can simply be cut off with a utility knife. The seal or fitting will need to be replaced with new ones if broken.
The water is not heated
A breakdown of a heating element in a boiler is the most common reason why a coffee machine stops heating water. This is most often due to the use of hard water. If the boiler is noticeable with leaks and lime deposits, it must be replaced. However, in the event of a malfunction, the boiler may look whole outwardly. Then you need to make sure that voltage comes to the heating element. This can be done using a multimeter or indicator screwdriver. However, you should not undertake this without the appropriate skills and experience. The heating element operates at 230 V. If you make a mistake, you can easily get an electric shock.
If there is voltage on the heating element, but there is no heating, then the problem is in the part. The breakdown is solved by replacing the boiler.
But if there is no voltage and all the wires are intact, most likely there is a breakdown in the control controller. There is nothing you can do about it – you have to carry the car to the service center.
The coffee machine does not “see” the water
If, when the tank is full, the machine signals a lack of water, it is possible that the matter is in the float of the corresponding sensor. Most often, it collects water and drowns due to the pouring of boiling water into the tank. The air in the float expands and damages it. Fill the reservoir with water (if it is removable, with its own float, it is easier to remove it first). Look at the float.
Didn’t surface? We need to change. You can try to seal it, but this is a temporary solution and does not help for long.
Coffee is brewing too slowly
No visible breakdowns or error messages, but does it take much longer to prepare a cup of coffee than before? Most likely, the problem is that the coffee machine has not been cleaned for a long time. There is no universal instruction here, each model is cleaned in its own way. Please refer to the instruction manual. Some models clean automatically, some have to be washed by hand.
Cleaning of the water circuit and decalcification are usually carried out using special means. In the most extreme cases, citric acid can be used. The cleaning task is to remove limescale deposits. Be sure to also clean the water filter (if you have one).
The brewing unit must be free of coffee oils. Automatic machines have a block cleaning mode using special detergents. In some machines, the part must be removed and cleaned by hand.
It is also worth cleaning the mesh above the horn, through which water flows – over time, it can become clogged. If the machine has a cappuccino maker, it can also be removed for rinsing.
The grinder does not grind the coffee
Does the mill rotate but the grains are not milled? Most likely, the millstones are clogged in the coffee machine. This can happen if you put ground coffee in the bean tray. You will need to disassemble the mill and clean the millstones. To do this, you need to refer to the diagram of your model.
It is worth noting that coffee deposits can literally turn into stone. They may need to be cleaned out with a screwdriver or knife edge.
The coffee machine does not work
What to do if the coffee machine simply “died” – the indicators do not light up, the buttons do not respond to pressing? There can be many reasons, including quite simple and easily eliminated ones.
First of all, check the power supply to the coffee machine. Make sure the power outlet is energized and check the power cord for kinks or damage. Many appliances have a separate main switch on the case near the power cord – try turning it off and on.
On some machines, protection is triggered when the mill cover is opened or any blocks are removed. Make sure the machine is assembled correctly, all units are in place, and all covers are closed.
Remove the cover of the coffee machine, check with a multimeter or indicator screwdriver. In this case, it is worth taking precautions to avoid electric shock.
If there is no voltage at the control unit, it is possible that some kind of fuse has blown. Unplug the coffee machine and let it cool down. Sometimes a triggered thermal protection prevents turning on the machine. If all else fails, you still have to carry the car to the service center.
