And most importantly, your coffee machine will be repaired in the shortest possible time, and you will be able to enjoy a high-quality drink again!

When can you fix the problem yourself?

Sometimes the owner himself finds and corrects a defect due to which coffee does not flow from the coffee machine. This is possible with minor problems that do not require much intervention in the design:

  • Water begins to flow from under the horn.

A flowing stream of hot or cold liquid indicates wear on the rubber seal. It is necessary to thoroughly rinse and dry the place where the gasket is installed, and install a new rubber band. It must be remembered that the seal must be selected carefully: it must correspond to the original.

A similar situation occurs as a result of a clogged filter. It is easy to fix: rinse the filter thoroughly and install it back.

  • Noise and weak pressure in the horn.

When you notice that the drink is not flowing well from the machine, or does not flow at all, you can have little doubt that the cone is clogged. It can be removed independently using special detergents. Try checking the filter: it may also be clogged. Just rinse it with running water and adjust the grind level of the beans.

  • There is no power supply.

Check the cord and outlet for damage. Often, because of this, the machine does not dispense coffee to you. If they are in order, contact a technician: there is probably a problem with the operation of the electrical unit.

Pressure gauge failure

Modern coffee machines are equipped with two pressure gauges - a pump and a boiler . They can be placed in one block or separately. The boiler pressure gauge controls temperature and pressure, it notifies that the device has reached operating condition - the same 1.1-1.5 atm. If the car has one pressure gauge, this thing works for the boiler.

The pump pressure gauge controls the pressure in the brew group. The operating parameters in this case correspond to 9 atm . Deviations from the norm indicate a breakdown.

Causes:

  • tubes are clogged with scale (solution: cleaning or replacing with a new one);
  • clogging the channels leading to the pressure gauge;
  • pressure gauge failure.

Solution : replacement of the unit or tubes at a service center, decalcification.

Recommendations for care and use

To make your coffee machine last longer, you should follow a few simple rules for its use and care.

  1. Read the operating instructions before you begin.
  2. Use clean drinking water. It is advisable not to pour tap water (not purified by a filter) or mineralized liquid into the compartment (minerals remain on the heating element). Bottled is suitable for coffee machines.
  3. Choose your coffee carefully. Do not use flavored, raw or coarsely ground coffee.
  4. If your machine has a removable brewing unit, try to wash it under warm water and detergent once a week.
  5. To clean parts, use products recommended by the manufacturer. As a rule, their names are indicated in the instructions.

Owners often experience problems with coffee makers due to improper use. Repairing or replacing parts in this case can be quite expensive. Therefore, I recommend following simple rules that will help you avoid unexpected breakdowns and maintain the functionality of your equipment for many years.

Why does equipment break down?

Conventionally, all breakdowns can be divided into two groups.

The first includes:

  • factory defect - there is a scheme for returning the device back;
  • lack of timely preventive examination;
  • incorrect settings of the coffee machine - I advise you not to neglect reading the instructions;
  • mechanical damage, incl. falls, blows. Most often this occurs due to improper transportation;
  • wear and expiration of components and parts.

The second group is:

  • the use of low-quality grain is an extremely common cause of breakdown;
  • lack of cleaning - provokes failure of the heating elements;
  • operation of the machine at low temperatures - you can count on problems with the hydraulic system and defrosting of the drainage system;
  • power surges , forced shutdown of the coffee machine, unexpected power outage - the control board often flies;
  • overload - if you choose a device without calculating the performance, there is a possibility of almost continuous operation, which will damage the machine.

Water is leaking from under the horn

If you find that your coffee machine is leaking, then there is no need to worry. This malfunction is not considered complex, and you can fix it yourself. Most likely, the leak was caused by a broken rubber seal. In this case, you should wash the contaminated area or replace the seal.

If your coffee machine is leaking, then it needs to be replaced. The O-ring must have the same characteristics as the previous model. If you just find a similar seal, then there is no need to install it. This product may not be resistant to elevated temperatures. If you are interested, then read about repairing a hood with your own hands.

When doing this DIY coffee machine repair, you need to check the filter of the coffee horn. Your filter may be clogged and you need to clean it. If you do not clean the filter regularly, then serious problems may arise.

If you see water running out of the coffee machine, then you need to inspect and replace the problem area. Usually these coffee machine breakdowns are your fault.

The filter is clogged: clean it yourself


The filter in the coffee machine is clogged.
It is important to change the filter correctly. Otherwise, you may end up with a plug of air, the pump will start working in vain, and ultimately this will become the reason why the coffee machine is noisy and does not work.

Change the filter as follows:

  • Turn the filter over with two holes facing up.
  • Pour water into it.
  • And also fill the car with water.
  • Install a filter.

If coffee does not flow well through the spout, then before calling service, check whether the filter is clogged.

Cappuccino maker does not work


The cappuccino maker in the coffee machine does not work.
When the cappuccino maker in the coffee machine does not work, well-frothed milk and foam will not work. There are usually two reasons:

  1. Stale milk.
  2. Channels are clogged.

Choose the right milk. Not powder and with a fat content of at least 2.5%.

The channels may become clogged because you do not take good care of the device. When you brew coffee with milk, you must clean the cappuccino maker afterwards. If you don’t do this, then over time the channels will become clogged and instead of foam there will be just hot milk.

Many machines now have a self-cleaning option. But if you have an old model, then you need to do regular cleaning yourself. Do not use sharp or hard substances.

The buttons in the coffee machine do not work


The buttons in the coffee machine do not work
If the Delonghi coffee machine or any other does not turn on, the buttons do not respond, then there may be several reasons.

First, make sure there is grain and water in the machine. Since some models do not run if they are empty.

Next look at the panel. Perhaps there is code on it that will help you understand what exactly is wrong.

And then you can carry out more serious diagnostics. Remove the front panel of the device and test the power circuit.

Sometimes the buttons just don’t work because coffee has been poured on them and they get stuck. You just need to clean up after yourself and the machine will start working.

If none of the above steps help, then you should contact the service. The coffee machine may not be working due to an electrical fault or because the fuse has blown. Such breakdowns must be repaired by a specialist.

What to do if the coffee machine gives an error?


Errors in the coffee machine
When there is an error code on the control panel or a light is blinking, you can refer to the instructions to understand what this means. It will also tell you how to fix the coffee machine. If you suddenly cannot find printed instructions, then open an electronic one on the Internet.

Usually the error appears due to a malfunctioning sensor. Cleaning and flushing the system will help. In this case, it is necessary that all containers are firmly in place and that the float in the water container works.
