Device of a typical coffee machine

In order to orient yourself in the breakdown, first of all, it is necessary to familiarize yourself with the internal device of household appliances. The design of the device does not represent anything complicated for those who have an idea of ​​the operation of such devices. And some of their parts can be found in washing machines, irons, electric kettles. Let's take a closer look at all the main elements of the coffee brewing machine.

Engines and pump

This device has two engines, and sometimes three. For home appliances - it's almost a record:

• The servo of the grinder is under the compartment in which coffee is loaded. Depending on the model, it can have a speed regulator.
• The second drive serves to rotate the connecting rod, on which stands a cup of ground coffee.
• Compressor of the coffee machine creates a pressure equal to 15-20 atm. At the entrance to the boiler there is a non-return valve, and at the outlet there is a bypass valve.

Coffee dispenser

The process of brewing coffee from the beginning to the end looks like this:

1. Straight from the millstick, a brown powder is poured into a horizontally standing cup, which is placed on the vertical connecting rod.
2. After the grinding has ended, the appliance motor stops, the servo drive of the coffee feeding system is switched on. He tilts the cup on the connecting rod and pushes it up to the reservoir for welding.
3. Then the water is supplied to the boiler from the bottom and flows out through the opening in the infusion tank.
4. The coffee dispensing mechanism moves the bowl down. On the way through a special slot falls down a pill.
5. After this, the bowl again returns to the mill to prepare a new portion of the fragrant drink.

Boiler for coffee machine

This part consists of two halves, connected by a large number of bolts through a gasket. Boiler walls are profiled. Thus, the reservoir can withstand a great deal of pressure. The heater is located outside, and not inside, which contributes to the prolongation of the service of the device.

Important! Heating water for making coffee is carried out to 95 degrees. Cappuccino requires steam, so the boiler heats the water to 127 degrees.

The main breakdowns of the kitchen appliance and the repair of the coffee machine

Let's consider the main problems that can arise during the use of the kitchen unit for making coffee.

Water leakage from under the horn

Such a malfunction is not considered a serious breakdown. It can be easily repaired by yourself.

Most likely, the reason for the flow of water where there is a docking of the hull and the horn is the clogging of the sealing ring at the junction of the coffee machine body and the "spout".Dirt can have a different nature: wet cake, fatty deposits, foreign objects, coffee and the like. Damage to the seal can also be a cause.

Important! The reverse situation - when the coffee machine does not pump water, is due to a malfunction of the piston, which is above the brewing device. You can also try to adjust it yourself after a thorough visual inspection.

Troubleshooting:

• To adjust the device, it is necessary to simply maintain the coffee machine for optimum service. To do this, clean and thoroughly rinse the contaminated area, then reassemble the horn.
• If the sealer is torn or cracked, replace it with a new one.

Important! A new O-ring must necessarily be exactly the same as a damaged one. If you just pick up a part only in form, you may be confronted with the fact that the rubber will not withstand high temperatures.

• Also it is necessary to believe the horn filter before installing a new seal. Perhaps it is clogged with coffee deposits, respectively - the breakdown occurred because of the clog.

Important! Similarly, you can replace any other stuffing box that does not cope with tightness. As soon as they saw that the water ran from the appliance, immediately find the reason for this and fix the problem until the water has got on the wiring and the electronic unit.

Appearance of extraneous noise from the inside, pressure decrease from the horn

If during operation of the kitchen appliance you notice that the water is flowing badly from it and whistling or noise is produced, it is most likely that the filter or the mesh in the horn has clogged.

Troubleshooting:

• The screen mesh and filter must be rinsed. For cleaning and maintenance of the espresso machine on sale there are special means from fats. Sorghum can also be quickly removed with a toothpick.

Important! The main thing is not to scratch or damage the internal capacities of the unit, as this will cause a delay in ground coffee and contribute to the rapid clogging of the machine.

• You should also check the amount of grinding coffee beans, because the cause of blockage can be covered in this. If your device allows you to adjust the amount of grinding yourself, do it.

Important! One of the reasons for the buzz and noise of the espresso machine during operation and poor water allocation is the wear of the internal pump mechanism. In this case, the repair of the coffee machine is reduced to replacing the pump.

Extraneous noise and total absence of operation of the

This breakdown can have several causes.

Option No.1

If the device takes water and heats, but does not give out coffee, then the cause of the malfunction in the formation of the airlock.

Troubleshooting - it is necessary to pass hot water through the cappuccino. Such actions should correct the malfunction.

Option No. 2

If the coffee flows from the spout of the kitchen unit with a weak jet, this indicates clogging of the nozzles.

Troubleshooting - the entire system must be rinsed with a special-purpose detergent.

Option # 3

A breakdown in electronics can also cause this behavior of the coffee machine.

In this situation, it is not recommended to repair the coffee machine yourself. Therefore, it is better to take the device to a service center where it will be put into operation.

Important! The electronic block about the clogging of the system must be signaled independently, displaying an exclamation mark or an error described in the instruction manual.

Buttons do not work

If the device does not react at all to pressing the buttons, there may be several reasons:

• First of all, you should check if there is coffee and water in the respective tanks. Most modern appliances are not switched on at idle.
• Inspect the display carefully. Remove the front panel, ring all the buttons multimeter for power.
• Button sticking may occur due to inaccurate handling of the unit - due to the fact that they were filled with coffee. Remove sticky residues with cotton wool soaked in alcohol.

Important! If all of the above actions did not lead to the desired result, and the coffee machine still does not respond to pressing the buttons, then it is necessary to ask for specialized help to the master. The cause may be a malfunction of the electronic control unit.

No power

If the coffee brewing machine does not work at all, that is, does not react to the connection to the network and pressing buttons, the display of the device does not light up, the reasons can be either simple or requiring diagnostics specialists.

Troubleshooting:

• First of all, check the integrity of the device cord and the power supply in the outlet.
• Check that the coffee machine door is closed. Most modern instruments have protection against turning on when the brewing unit is open. Perhaps the technique is not included for this reason.
• If you have not found any obvious reasons, then it's necessary to start disassembling the case. It is necessary to ring all the parts of the chain, starting from the cord and ending with the elements of heat protection using a multimeter.
• If the malfunction has not been detected, then the coffee machine should be carried to the service center for diagnostics and repair.

The appliance does not see coffee

Sometimes it happens that the machine does not see coffee, although it is filled in a suitable tank. This happens for the following reasons:

• engine or coffee machine with funnel is faulty;
• broke the control unit.

Troubleshooting:

• If you find that the inside of the mechanism is covered with coffee dust, it means - the cause of the breakage in the broken coffee machine, which caused the dust from the coffee and got into the engine compartment. Repair of the coffee machine in this case is reduced to the replacement of the engine.

Important! Often, such a replacement is not practical because of the high cost of parts, and it is easier to buy a new device.

• The absence of coffee can be a consequence of clogging of the brewing device or too little grinding of the coffee beans. To begin with, try setting a little more grinding on the coffee machine and cleaning the brewing device.

Knocks an error on the

display If the indication on the front panel lights up or the instrument displays an error, the first thing to do is to refer to the device's operation manual. There should be indicated all possible errors, the reasons for their occurrence and the ways of repair.

Troubleshooting:

• You can try to completely clean and rinse the system. Often, such actions help to fix the problem.
• Make sure that all containers are inserted completely, and the float in the water tank is working.

The water in the

does not heat up. This problem is very common in similar devices. Her zealously discuss in all sorts of forums. Water does not heat up to the right temperature and does not brew well with coffee. The cause of this behavior of the apparatus may be the failure of the heating element. In addition, the heating level may not correspond to the required level due to a malfunction of the controller.

Troubleshooting

All you can do yourself is to call the multimeter of the heater and the controller. This will allow finding the faulty part of the network for further replacement.

Important! The poor quality of drinking water, namely, increased stiffness, also often causes poor heating of the liquid in the coffee machine.

The

rocker failed. If the cappuccino breaks, the appliance does not whip the milk and turns it into milk foam. As a rule, the reasons for this are poor quality milk or blockage of air channels, which create foam.

Troubleshooting:

• Use only non-powdered, pasteurized milk with a fat content of 2.5 to 3.5%.
• Servicing the coffee machine should include regular cleaning. After each preparation of coffee with whipped milk, it is necessary to rinse the cappuccinator with clean water for 2-3 minutes.
• If the espresso machine does not suck the milk when the appropriate mode is activated, it is recommended to check the milk supply system for clogging and the pump.

Important! Most modern coffee machines have an automatic washing function. If your device does not have one, you should perform the cleaning yourself. Do not use sharp or hard objects when flushing air ducts. This can lead to damage to the hole and the kapuchinator generally may stop working.

The filter in a container with water is contaminated.

The water filter must be replaced very carefully, because incorrect actions can lead to the formation of an airlock in the system, idle operation of the pump and its subsequent failure.

Important! Running the pump in idle mode can cause the noise of the coffee machine without its subsequent operation.

Servicing the coffee machine to replace the filter:

1. Turn the filter upwards with the inlet and outlet.
2. Pour it completely with tap water.
3. Pour water into the appropriate container of the coffee machine.
4. Perform the installation.

Does not display the presence of water

If the device does not react to water with a full tank, the problem is a malfunction of the float sensor.

Troubleshooting:

• Check the integrity of this element in this way: pour water into the container and see if the float has risen to the top. If it does not rise, it is probably clogged or flooded with water.
• Clean the working area of ​​the float, and dry the sensor. If such actions lead nowhere, then replace this element with a new one.

Important! The cause of moisture penetration inside the float can be covered by the fact that hot water is poured into the coffee machine. Such actions are contraindicated for a coffee machine.

The

manometer has broken. The pressure monitoring system may be damaged during operation of the coffee machine.

It is necessary to clean the tube that goes to the manometer.

Important! If such actions lead to nothing, the manometer should be replaced with a new one with exactly the same characteristics.

The coffee machine does not grind grain

There are situations when the appliance refuses to grind the coffee beans, and because of this can not brew normal strong coffee.

Troubleshooting:

• Disassemble the enclosure and clean the coffee grinder thoroughly. As a rule, such actions immediately solve the problem.
• If the grinder does not grab the grain, adjust the grind level.
• If after that the machine does not process the grain, it is better to contact the master.

Problems with the coffee capsules

Sometimes there are problems with the fact that the capsules or tablets are not pierced. In this case, you do not need the repair of a coffee machine, but practical advice on the correct location of the capsule.

You must toss the tablet so that it falls flat on the piercing surface, and then press the lever. Even a slight distortion can cause the mechanism to fail to squeeze or eject the capsule.

It is not always possible to diagnose and eliminate the failure of the coffee machine on your own. If you are lost in the reasons or are afraid to make even an elementary disassembly of the case, it is better to immediately go to the service center, where the full service coffee machines. Frivolous failures are eliminated quickly and inexpensively, and with more global you can not independently cope.
