How to disassemble a coffee machine?

To repair the coffee machine, you need to disassemble it first. And how to do it correctly, step by step is described below.

  1. It is necessary to find the back wall of the device, or rather the set screws. Unleash a screwdriver, pliers or what was at hand and is ideal for such work, set aside. It should be noted that there may be several screw options. They can be hidden, cross or domed;
  2. Screws removed, it is logical that the cover should be easily removed. However, if it cannot be removed, then there are hidden locks in the case. Most often these are ordinary plastic latches and they are located at the bottom of the back cover. Outside, such a lock can be easily opened with a knife or a small screwdriver;
  3. Finally, access to the "insides" of the machine, it is time to start the repair.

And so let's go in order. A blockage appeared in the water supply pipe. In such coffee machines as: Delonge, Bork - Bork, Ariete - Ariete and others, cleaning is done with a long and thin rubber hose. It is necessary to run through the duct and thereby pierce the blockage. However, it will be much more effective to use special brushes on a flexible leg.

A little harder to do your own filter cleaning. With frequent use of the coffee machine on the filter accumulates: scum, coffee residues, salt plugs, etc. It is necessary to approach cleaning carefully, but the most important thing is to do it according to the instructions, otherwise it is possible to break the integrity of the part. The process allows the use of a soft swab sprinkled with alcohol. After cleaning, rinse the filter thoroughly.

Tip:

If you are unable to solve the problem yourself, contact the Saeco coffee machine service center.

Moulinex, Krups, Roventa, Saeko coffee machines have another problem - water is leaking. In them, the valve regulating the flow of water, is located almost in the filter. If the coffee does not stop pouring, the worn valve is most likely to blame, which leads to such a phenomenon.

Valve cannot be repaired, in this case only a replacement for another new part is available. To understand whether the valve is broken enough to pour coffee out of the machine, disassemble, rinse and inspect well the possible damage.

Coffee maker does not turn on

  2. It also happens that household coffee machines made in heaven just lose contact( they depart).Such cases have also been encountered with more famous brands: zauber, melitta, trevi. It is enough to check all the connections of the wires to the control circuit.
  3. A common case for Senseo¸Siemens machines, Ufesa, low-quality thermostats are built into them. To diagnose it, it is necessary to remove one wire from its end and “ring out” the contacts with a tester. If all goes well, the circuit will be closed.
  4. TEN can also fail. Diagnostics are made similar to a thermostat. Replacing it with a new one is difficult, it will be easier to try to repair or buy a new coffee machine.
  5. Very often, on the shelves near the coffee machine, all the necessary accessories are sold, which you will certainly need for the correct operation of the device. And for cleaning the details of equipment, it is always advised to buy special flexible brushes.
