We closed the hatch door, pressed “Start”, and after a while we noticed that the machine had stopped and the F4 code was on the dis­play. What to do? What does the F4 error mean in the Atlant wash­ing machine? How to fix the prob­lem your­self? You will find answers to all these ques­tions in this arti­cle.

Error decoding

F4 error in Atlant washing machine

Error F4 on the dis­play of the Atlant machine says that there are prob­lems in the drain sys­tem and it is not pos­si­ble to drain the waste water from the tank. Before call­ing the mas­ter and pan­ick­ing, you should find out if there is a rea­son for pan­ic and under­stand what the prob­lem is.

On wash­ing machines with­out a screen, the on / off light and the sec­ond indi­ca­tor in the bot­tom row will be lit.

How to fix the error yourself

Before call­ing the mas­ter and pan­ick­ing, you should find out if there is a rea­son for pan­ic and under­stand what the prob­lem is.

  • Con­trol fail­ure. To resolve this error, you must restart the Atlant wash­ing machine. To do this, turn it off using the pow­er but­ton and unplug the plug from the out­let for 5–10 min­utes. After that, turn on the machine again. If the error was ran­dom, then the code will not appear.
  • Block­age in the fil­ter. Often, the F4 error appears due to debris in the drain fil­ter. Var­i­ous threads, a tri­fle from pock­ets clog holes over time and water does not pass. In this case, the block­age must be removed. To do this, drain the water man­u­al­ly, after lay­ing rags, then unscrew the drain fil­ter and clean it of debris. At the end, put every­thing back in place and check for errors. If it dis­ap­pears, the cause has been elim­i­nat­ed.
  • Block­age in drain hose. It often hap­pens that debris under the action of the pump pass­es into the drain hose and clogs it, there­by block­ing the pas­sage of water. To solve this prob­lem, you must first drain the water, then dis­con­nect the drain hose and clean it under a strong stream of hot water, then return it to its place and start the Atlant machine again in the spin mode. The error code should dis­ap­pear.
  • Block­age in the sew­er. Often the cause of the F4 error on the Atlant type­writer is a clogged siphon or sew­er pipe. To diag­nose such an error, it is nec­es­sary to pull out the end of the hose con­nect­ed to the drain and turn on the spin mode. If the error did not appear and the water was safe­ly drained by the machine, then it is nec­es­sary to clean the sew­er pipe with a steel cable, or a siphon, hav­ing dis­as­sem­bled it.

Faults requiring repair

Unfor­tu­nate­ly, not always the cause of the error is a sim­ple mal­func­tion. There­fore, it is nec­es­sary to be aware of oth­er pos­si­ble rea­sons.

signs Cause Solu­tion
The Atlant wash­ing machine does not drain the water and freezes in the wash or in the rinse mode, shows the F4 error. Drain pump defec­tive.

Pos­si­ble rea­sons:

  • The coil of the motor con­nect­ed to the pump has bro­ken;
  • A short cir­cuit has occurred in the pump motor;
  • Dam­aged drain pump impeller

The pump mal­func­tion occurs due to the devel­op­ment of the norm of the resource of the watch or when small objects get into it.

The pump needs to be replaced.
While drain­ing the water, the Atlant machine makes a hum and the water does not go away. In this case, there is a code F4. Clogged pump (drain pump).

All kinds of small items, var­i­ous debris from pock­ets, twists of thread or wool, slip­ping through the drain fil­ter, enter the pump and block its nor­mal oper­a­tion.

It is nec­es­sary to dis­as­sem­ble the pump and clean it of for­eign objects.
Clogged drain pipe.

The branch pipe locat­ed between the drain fil­ter and the tank is also prone to clog­ging with var­i­ous objects (thread, wool, small change, etc.).

It is nec­es­sary to clean the noz­zle from block­age.
The wash­ing pro­gram is inter­rupt­ed and code F4 is dis­played.

The appear­ance of an error is pos­si­ble at any stage of the pro­gram (rins­ing, spin­ning, wash­ing), and it is also pos­si­ble that it will appear imme­di­ate­ly after start­ing.

Defec­tive elec­tron­ic con­trol mod­ule.

Main rea­sons:

  • Due to the pos­si­ble ingress of mois­ture, oxi­da­tion or com­bus­tion of ele­ments on the board;
  • Dam­age to cir­cuit ele­ments;
  • Firmware fail­ure;
  • Mal­func­tion in the micro­proces­sor
In cas­es of fail­ure of cir­cuit ele­ments for var­i­ous rea­sons, their replace­ment is nec­es­sary.

If the error occurs due to a firmware fail­ure, you should reflash the con­troller pro­gram.

If the above meth­ods did not help get rid of the error, or it was caused by a mal­func­tion in the micro­proces­sor, then a com­plete replace­ment of the board is nec­es­sary.

The wash­ing machine drains water dur­ing wash­ing and stops, show­ing error code F4.

Atlant hung dur­ing the spin cycle and showed an F4 error. The door is locked.

The pres­sure switch is faulty.

The sen­sor respon­si­ble for the water lev­el in the tank does not work. The con­troller does not receive a sig­nal from an emp­ty tank. Most like­ly there was a short cir­cuit in the sen­sor con­nec­tion cir­cuit.

The pres­sure switch needs to be com­plete­ly replaced.
The Atlant wash­ing machine stopped at one of the points of the wash­ing pro­gram. F4 error is dis­played Faulty pow­er sup­ply to con­trol units.

The pump or pres­sure switch is not sup­plied with pow­er or the con­trol sig­nal is inter­rupt­ed between these nodes and the con­trol board. This is due to oxi­da­tion of the con­tacts, bro­ken wires, or a short cir­cuit in the wiring.


If the con­tacts are oxi­dized, they must be cleaned or replaced.

If there is a break in the wires, they should be replaced.


No one can exclude the appear­ance of mal­func­tions in the oper­a­tion of the wash­ing machine. There­fore, this arti­cle will be use­ful to all users of the Atlant machine. Often, the error code is caused by sim­ple mal­func­tions that you can deal with on your own by read­ing them in the sec­tions above.
