DIY repair of the washing machine programmer

The programmer is one of the most important control parts in the washing machine, which is responsible for choosing the necessary washing mode, including spinning, soaking, and for newer models of machines, as well as for drying. The programmer is also called a command device or timer, it is used in most automatic washing machines and looks like a protruding round handle on the control panel.

Without a programmer, only machines with a microprocessor and the presence of fuzzy logic functions, control in such units is carried out through the touch or keypad. And if the programmer fails, then washing in such a machine is impossible. But how to understand and verify that the malfunction of the machine is in this part, whether it is possible to repair it with your own hands, we suggest to sort it out together.

Programmer device

The programmer is an important unit of the control unit in the washing machine, which consists of a large number of parts.

These parts may break down over time, which means they may need to be repaired. But in order to carry out such repairs, you need to deal with the device of the programmer. The electromechanical command device of an automatic machine includes the following main elements:

• synchro motor;
• gearbox;
• contacts;
• gears;
• cams (protrusions and recesses) driving a synchro motor.

Programmers are of two types:

• Hybrid
• electronic.

A hybrid command device is considered the most reliable, but at the same time its functionality is limited. The electronic components of the control unit of the machine are more perfect, have a large number of functions and fine tuning. But they are subject to more frequent breakdowns, can respond to power surges, go astray, turn off arbitrarily.

Signs of a breakdown and its causes

A programmer breakdown can be determined by several signs:

• the machine has stopped turning on and at the same time everything is in order with the electric network, the cause of the malfunction can be caused by one of the elements of the control unit and the control unit, including;
  

  Be sure to before disassembling the machine, do not forget to check the network cable and outlet for breakdowns.

• during washing, the program crashes, the time does not correspond to the selected mode;
• in some models of washing machines, an external sign may be a blinking of all indicators on the control panel.

Despite the fact that the command device is a fairly reliable part of the washing machine, but even after 10 years it may break. The main reason that the wizard notes is the careless handling of users with the unit. So, for example, if a child came up to the typewriter during washing and began to twist the knob, then this may be enough for the programmer to fail.

Another cause of breakdowns is power surges. In addition, moisture inside the programmer may also cause a malfunction. Well, we do not exclude marriage in the production of parts.

We disassemble the programmer

Programmer repair begins with its proper disassembly. The problem is that there are a lot of varieties of programmers, and there is nothing to talk about models, each model has its own disassembly features. We will tell about the features of disassembling the programmer using the example of a device from an automatic washing machine Ariston. The procedure is as follows:

• We take the programmer removed from the machine and carefully examine it. We find on the side the latches holding the plastic cover, pry them with a screwdriver and remove the cover.

Important! When removing the cover, be extremely careful, under it there are several small springs that tend to fly apart when disassembling the programmer, do not lose them.

• After we remove the cover, under it we will see an inverted board.Carefully take it out and set it aside.
• We take out the central gear and examine the small gears. Often garbage is clogged in them, which interferes with the normal operation of the mechanism.
• Now carefully inspect the board. Often on it you can see burnt elements or tracks. They will have to be re-soldered.
• If there are no burnt tracks, then we take a multimeter and measure the resistance at the contacts of the control board, there is something there.
• We continue to disassemble the programmer. Now our task is to remove all the gears one after another, and then the core of the programmer motor.
• Next, you need to visually check the integrity of all elements, wipe the contacts with alcohol and assemble the device in the reverse order. Repair of this control is complete.

Note! When disassembling the programmer engine, do not forget to inspect the winding, because it can also burn, which will disrupt the operation of the control device. If a burnt wire is found, it will have to be removed, and a new one should be wound in its place.

Experts categorically do not advise taking DIY repair of programmers of German washing machines like Miele or Siemens. Their devices have a complex structure, represented by several compressed pairwise plates. When you start disassembling such programmers, the plates scatter in different directions and it is extremely difficult to assemble them later, since fragile plastic grooves damage the plates when they expand. For our part, we advise the masters to entrust the repair of programmers from German washing machines.

It should be noted that German programmers are not the most difficult. In washing machines Gorenie, installed programmers with a soldered control board. To carry out their repair, you need to masterfully own a soldering iron, not ordinary, but special with a thin sting. Even the majority of masters do not undertake the repair of such programmers, therefore, for our part, we advise you not to waste your energy, but simply replace the broken programmer from the Gorenie washing machine with a new one.

In conclusion, we note that it is far from always a grateful thing to repair a machine’s command machine with a do-it-yourself machine. There are devices with the simplest design, in which it’s not a sin to dig deeper, it can and will not succeed, but it will not be worse. But another command device is so complicated that repairing it is simply not advisable, or you can do it only to a good master.
