Error F9 in the Atlant washing machine: troubleshooting

To be honest, Belarusian washing machines are not reliable. And that's a fact. According to statistics from service centers, this unit takes an honorable third place in the list of models that break down after 3 years of operation.

It’s good that at least these products have a built-in automatic diagnostic system that notifies users about what exactly happened to their irreplaceable assistant and how they can help her. In particular, many users are faced with the fact that error F9 occurs in the Atlant washing machine.

We will talk about what kind of beast this is and how to fight it in this article. By the way, if you have a model without a display, don’t be upset. They also notify about errors and various types of malfunctions. But this happens not through the display, but through the light indication. Code F9 corresponds to the lighting of the first and fourth LEDs.

What does error F9 mean?

If this error code lights up, then problems arise with the rotation of the drum. The tachogenerator may fail, the engine or control module may break down, or problems may arise in the wiring connecting these elements to each other.

It also happens that no error occurs at the hardware level. In Atlanta, there may be a problem with the firmware of the electronic board. And after even a slight power surge, the firmware crashes. In this case, repairs will also be required, but not an expensive replacement of the electronic board, but simply its re-flashing. Although it will not be possible to do this at home without special knowledge, experience, or tools.

Before suspecting a breakdown in the machine, it is important to rule out a one-time failure. This can happen if the control board freezes. In this case, we proceed like this:

Unplug the washing machine cord from the outlet and wait at least 15 minutes, preferably more.
Turn on the equipment.
If the error disappears from the display, then everything is ok, and it was really a one-time failure.

Also check the spin button. An error may occur if the spin button is pressed accidentally. This also happens.

And if it was not possible to eliminate the malfunction in this way, most likely we are dealing with a breakdown.

Error F9 in the Atlant washing machine: troubleshooting

Checking the tachogenerator

To check the serviceability of the SMA tachometer yourself, follow these steps:

Turn off the power.
Unscrew the bolts holding the back cover of the equipment. This is very easy to do, just unscrew the screws.

Under the cover you will see a large pulley with a drive belt, the back wall of the tank, pipes, heating element contacts and the wires to which they are connected, an engine with a tachometer connected to it.

Note! The advantage of Atlanteans is that they have a convenient arrangement of internal elements. By removing the back cover, you will have access to all the main components at once. This does not happen in all machines. In other brands, difficulties begin already with removing the back cover.

So, to check the tachometer we do the following:

disconnect the wires that go to the tachogenerator,
take a multimeter and check the part.

The normal value at the Hall sensor contacts is 60 ohms. After that, set the multimeter to Voltmeter mode. Applying the probes of the device to the contacts of the tachogenerator, start rotating the motor; the voltage should increase by about 0.2 Volts.

Remove the tachogenerator and visually inspect its ring. Perhaps a layer of oxide has formed there. If so, the ring needs to be cleaned.

Pay attention to the quality of fastening of this part. Perhaps the reason is not a problem, but that a part has become loose? This sometimes occurs due to constant vibrations, especially at high spin speeds. To get rid of the problem, just tighten the sensor.

Also check the cables between the board and the part. If, as a result of the measurements, it was discovered that the tachogenerator had burned out, it would need to be replaced with a new one.

To do this, purchase the part in online stores or other points of sale. It is advisable to install original spare parts. After that do the following:

remove the back cover;
Unclench the harnesses and disconnect the wires from the sensor;
release the latches to remove the back cover;
unscrew the fastening;
remove the burnt part;
Install a working spare part and perform all steps in reverse order.

Possible breakdowns requiring repair

Error value F9 indicates a malfunction of the tachometer. First of all, it needs to be checked. But engine-related breakdowns can also be the cause of the error. Below we will analyze all the malfunctions associated with this error.

The tachometer (tachogenerator) failed - from 1800 rubles*

It measures the rotation speed of the drum and transmits data to the control module. If the tachometer fails, then the Atlant washing machine does not spin the drum and displays error F9. The code lights up on any program during or after drawing water.

HOW TO FIX

To check the tachometer, you need to put the multimeter in dial mode, then connect both probes to the contacts of the tachogenerator and rotate the drum. If the sensor rings and the tone of the sound changes when the drum rotates, then the sensor is working. Otherwise, the sensor has failed and needs to be replaced.

The control module is faulty - from 1800 rubles*

The module “manages” all the components in the washing machine. If error F 9 occurs, elements in the tachometer or motor circuit fail: relays, motor triacs, resistors, etc. Sometimes the firmware gets lost, the tracks burn out or oxidize. Because of this:

the Atlant washing machine does not rotate the drum at all;
he twitches a little;
After starting the program, the drum spins a little only in one direction, and then an error is displayed.

HOW TO FIX

It is necessary to ring the tracks, board elements in the engine or tachometer circuit and identify faulty ones. Then, suspicious tracks are soldered, faulty elements are replaced with new ones. If the cause of the error is a failure of the control unit firmware, then the memory chip is unsoldered, reprogrammed using a special device and soldered back in.

If the damage to the board is too great and/or the microprocessor has failed, then the control module is replaced completely.

The graphite brushes of the engine are worn out - from 1300 rubles*

Carbon brushes transmit electric current to the motor rotor and ensure its rotation. The motor transmits rotation to the drum using a belt drive. Over time, the brushes wear out and lose contact with the engine commutator. Due to poor contact, the motor sparks, and the Atlant washing machine first stops spinning and then completely stops spinning the drum on any program. Error F9 lights up on the screen.

HOW TO FIX

The critical length of the brushes is 1 cm. If it is shorter, they completely lose contact with the commutator and need to be replaced with new ones.

The motor has failed - from 1800 rubles*

If the control unit is the “brain” of the washing machine, then the engine is its “heart”. It sets the washing machine drum in motion. When the motor fails, the Atlant machine only takes in water, the drum does not rotate, and error F9 is displayed.

The following reasons lead to failure of the electric motor:

break in the working and/or starting winding of the motor;
interturn short circuit in windings;
detachment of lamellas and breakage of contact in these nodes;
current leakage to the housing in the motor.

HOW TO FIX

Engine replacement required.

How to check an electric motor?

An Atlant brand washing machine may indicate a malfunction with error F9 if there are problems with the electric motor. If there is a current leak to the housing, or the armature is broken, there is nothing you can do, the part cannot be repaired and you will have to replace the unit. And this part is expensive. Of course, theoretically the engine can be repaired. But this is not practical from an economic point of view. Such repairs will cost more than buying and replacing a broken part with a new one.

So, how do you determine that an engine replacement is needed? To do this, the motor must be removed. Disconnect the wires from it, unscrew the bolts and pull the motor towards you. Next you need to find the brushes, unscrew the holders and pull out these parts for inspection. If the brushes are worn out, they need to be replaced. You can tell if the brushes are worn out easily; they will be too short. By the way, always change brushes in pairs. And if: buy only original brushes, otherwise there is a risk of damaging the commutator lamellas and then the cost of repairs will increase significantly.

After this, we open the housing of the device and use the same multimeter to check for leakage on the housing, as well as the motor winding for breakdown. If there are no problems with the brushes or motor windings, and no leaks to the housing are detected, then everything is fine with the motor. We need to look for another reason.

Decoding the F9 code

The F9 coding indicates a malfunction in the operation of the device, which concerns the functionality of the tachogenerator . The washing machine fails to accelerate the drum to the required speed, and the control module, which coordinates the operation of the entire washing machine, interrupts these attempts by displaying an error message.

This could be one of the options:

In automatic Atlant washing machines that do not have a display, information about a failure is conveyed to the user by the glow of a certain combination of indicators.

An analogue of F9 for them are the following signals:

A failure with F9 in Atlant can occur at any stage of processing items in an automatic washing machine.

Checking the electrical circuit

If all the elements have been checked and the error code has not disappeared, it’s time to think about the serviceability of the wires connecting the engine and the control module. Take a multimeter and start calling each wire. If you find that any of them does not ring, you need to replace it. We also recommend not to trust single measurements and measure the entire cable bundle at least 2 times, since with the testing method under consideration, errors in measurements can sometimes occur.

Well, if the circuit is working properly, then the fault is still in the electronic module. You will have to contact a good service center, since it is not recommended to repair the control module yourself for the reason that you need specialized tools and skills. As we have already said, sometimes problems with the board are related to the firmware, and not to a hardware failure.

Control module and electrical circuit

We should return to such a detail as a chip. Using the same multimeter, ring each electrical communication wire. Replace damaged elements with new ones. Many technicians advise checking all wires twice, since errors are possible with this diagnostic method.

If the wires are in perfect order, then most likely the error lies in the control module. This is one of the main elements of the software of any washing machine. At the same time, it is a rather complex unit in design, execution and operation. Therefore, it is highly not recommended to repair it yourself. It is more advisable to entrust repairs to professional craftsmen to avoid even greater troubles.

Error F3 in Atlant cars without a display

If your Atlant does not have a screen, then it will report a problem using two signal indicators:

in SoftControl models , these are lights near the “Spin” and “Water Hold” LEDs;
in the OptimaControl series - “Water Stop” and “Rinse” LEDs.

Causes and remedies

In most cases, F9 indicates a problem with the equipment that requires repair. But sometimes the reason may lie in a random coincidence or in a user error.

Overload

It is not always possible to cope with a breakdown of the Atlant washing machine on your own. If simple reasons are not confirmed, and diagnostics of the condition of the motor and other components is required, it is better to entrust the work to a professional.

The cost of the technician’s work depends on the complexity of the repair and the company’s price list. The average prices for repairs in the capital are as follows:

The cost of new parts is paid separately by the customer. If repairs to other components of the device are required along the way, the cost of the technician’s work increases.

CAUSES OF THE PROBLEM

A message about insufficient water heating or its absence may appear due to the following reasons:

Failure of the heating element, or its inability to bring the temperature of the liquid in the tank to the required temperature due to scale. The water that enters the washer passes through the soil and is enriched with minerals. When heated, they form compounds that settle on the heating element in the form of scale. At first, this simply prevents it from performing its functions normally: thermal conductivity deteriorates, and it takes more time and energy to work. Gradually, these chemical compounds corrode the part and rust appears on it. Since the heater is in direct contact with the water in the tank, and electricity flows through it, it passes through the resulting gap in the insulation along the body of the machine. A short circuit occurs.
Damage to the channel connecting the heating element and the control unit. They communicate using wires. During operation, due to vibration, wires can become disconnected, contacts oxidize, and the normal transmission of information between the heater, temperature sensor and electronic unit is disrupted.
Temperature sensor malfunction. Depending on the model, it can be located either in the machine’s tank or on the heating element. If it fails, incorrect readings are transmitted to the control unit, and code f3 appears on the display of the Atlant washing machine.
Malfunction of the control unit itself. This is the most serious failure, since this part consists of many elements. In addition, the cause of “glitches” may be program failures. It is recommended to contact a specialist.
