Error F4 in the Atlant washing machine

Error F4 on SM AtlantThe F4 code on the Atlant washing machine appears at the most unexpected moment in the middle of the washing program, when it seems that the “home assistant” is working quite well, but in fact there has already been a breakdown that needs to be fixed immediately. About what the F4 error means, how to find and how to eliminate its causes, read in this publication.

Decrypt the code

Almost every washing machine Atlant It has a rather informative display, on which in case of a malfunction, a particular error is displayed, in our case, error F4. But there are models of "home helpers" of this brand who do not have a display, but there is a self-diagnosis system. A logical question arises, how to recognize the F4 error if the machine simply has nowhere to display it?

Not quite the right question, and here's why. The Atlant machine in this case gives an error using the LED indicators located on the control panel. In particular, in our case, you need to look at the bottom row of bulbs. The figure below shows the Atlant control panel without display, which displays the code F4. Please note that the on / off lamp and the second LED in the bottom row are lit.

No matter how the F4 code is displayed, the decryption is the same. Its essence is as follows: there were problems with the discharge of waste water from the tank. A more extensive decryption indicates to us a list of reasons why this error appears. Let's look at this list in the next paragraph.

Why does this code appear?

The appearance of the F4 error can be associated with various kinds of breakdowns, these include:

  • clogging of the drainage system and in particular the drainage filter or drain hose;

With regular cleaning of the washing machine and constant washing of the drain filter, the likelihood that the cause of the F4 code is caused by a blockage is low.

  • malfunction of the pump, namely jamming of the impeller or malfunction of its electrical part;
  • breakdown of electrical wires between the pump and the control module;
  • breakdown of the control module (triac or resistor burned out).

Eliminate the causes of the code

So, what does this error mean and the reasons for its appearance are clear, it remains to figure out what to do in this situation and how to fix it. Start with the simplest one, namely unplug the machine and inspect the drain hose for kinks. If you moved the car the day before, then it is quite possible that you accidentally bent the hose, so the water does not leave the tank.

Next, check the drain filter, which is located behind a special small door in the lower right corner. Unscrew the filter by placing rags under the machine or by substituting a low container under water. Rinse the part if necessary, and then return it to its place. On this, the simplest actions end, prepare the tools, you will need: screwdrivers, pliers, a multimeter. Now get started:

  • disconnect the machine from the network, water and sewage;
  • drain the tank if necessary through the filter hole;
  • extend the machine to a convenient place;
  • turn the equipment on the left side, you can lay a rag or an old blanket under it;

  • from the bottom you will see the pump, you need to disconnect the chip with wires from it;
  • then unscrew the three screws holding the pump and remove it from the machine;
  • Install a new spare part and assemble the equipment.

Note! In the Atlant washing machine, the Askoll series pump is usually installed.

If the washing machine generates an F4 error not because of the pump, then take a multimeter and consistently check the wires between the drain pump and the electronic module. Due to a broken wire, the pump does not start, and therefore water remains in the tank. The work is simple, but the average user may not be able to do it, keep in mind an electrician.

The last in the list of faults is the electronic module, firstly, because its breakdown is not so frequent, and secondly, it is not easy to repair it. To do this, you need special tools, an electronic module circuit of your washing machine and minimal knowledge in the field of electronics. Let us give an example of a module of a series of boards 5521хх, 5522хх, 5523хх for the Atlant machine.

SM Atlant module diagram

A synchronous motor for 230V and 0.3 A drain pump is connected to pins 1 and 2 of connector J2, circled in red in the picture above. The operation of the pump is controlled by a 0.8 A triac. It is these elements and their contacts that are checked first of all, and also inspect the module for other damage, burned out elements that need to be replaced are visually visible.

Thus, the Atlant washing machine in the event of the F4 code can be repaired independently, because in most cases the cause is a faulty pump. This part can be replaced independently, in other cases it is better to contact the master. Good luck

    Thanks for the step-by-step instructions. I fixed the malfunction, which consisted in blocking the impeller of the pump (rubber was wound on the blades). In this regard, the impeller of the pump could not rotate and thus he did not pump out water from the tank of the washing machine!
