Error F4 in the Atlant washing machine

Error F4 on SM AtlantCode F4 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 normally, but in fact there has already been a breakdown that needs to be fixed immediately. Read about what error F4 means, how to find and how to eliminate its causes, in this publication.

Let's decipher the code

Almost every washing machine Atlant has a fairly informative display, on which, in the event of a malfunction, one or another error is displayed, in our case error F4. But there are models of “home assistants” of this brand that do not have a display, but do have a self-diagnosis system. A natural question arises: how to recognize the F4 error if the machine simply has nowhere to display it?

This is not a completely correct question and here’s why. In this case, the Atlant machine generates an error using LED indicators located on the control panel. In particular, in our case, you need to look at the bottom row of light bulbs. The figure below shows the control panel of the Atlant washing machine without a display, on which the code F4 is displayed. Please note that the “on/off” light and the second LED in the bottom row are lit.

No matter how the F4 code is displayed, its decoding is the same. Its essence boils down to the following: problems have arisen with draining waste water from the tank. A more extensive transcript shows 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 error F4 can be associated with various types of breakdowns, these include:

  • clogged drain system and in particular the drain filter or drain hose;

If you regularly clean your washing machine and constantly flush the drain filter, the likelihood that the cause of the F4 code is caused by a clog is low.

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

Eliminating the reasons for the appearance of the code

So, what this error means and the reasons for its occurrence are clear, all that remains is to figure out what to do in this situation and how to fix it. Start with the simplest thing, namely, unplug the machine and inspect the drain hose for kinks. If you moved the washing machine the day before, 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 placing a low container under water. Rinse the part if necessary, and then return it to its place. This is where the simplest steps end, prepare the tools you will need: screwdrivers, pliers, multimeter. Now get started:

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

  • from the bottom you will see a 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.

For your information! The Atlant washing machine is usually equipped with an Askoll series pump.

If the washing machine gives error F4 not because of the pump, then take a multimeter and sequentially 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 not difficult, but an ordinary user may not be able to complete it, keep in mind that this is an electrician's job.

Last on the list of faults is the electronic module, firstly, because its breakdown is not so frequent, and secondly, it is not easy to repair. To do this, you need special tools, a circuit diagram of the electronic module of your washing machine and minimal knowledge in the field of electronics. Let's give an example of a module from the 5521xx, 5522xx, 5523xx board series for the Atlant machine.

SM Atlant module diagram

The 230V, 0.3A synchronous motor for the drain pump is connected to pins 1 and 2 of J2, circled in red in the picture above. The operation of the pump is monitored with a 0.8 A triac. It is these elements and their contacts that are checked first, and the module is also inspected for other damage; burnt-out elements that need to be replaced may be visually visible.

Thus, in the event of code F4 occurring, the Atlant washing machine can be repaired independently, because in most cases the cause is a faulty pump. You can replace this part yourself, but in other cases it is better to contact a specialist. Good luck!

    Thanks for the step-by-step instructions. Fixed a problem that involved blocking the pump impeller (the rubber band was wrapped around the blades). In this regard, the pump impeller could not rotate and thus it did not pump water out of the washing machine tank!
