The Atlant washing machine is equipped with a self-diagnosis system: when it finds a malfunction, it immediately displays a specific code on the display.
Let's see what the F9 error means on the screen of electronic models. On Atlant washing machines without display, error code F9 is identified by the glow of the first and fourth indicators.
Code decryption, causes
Error F9 in the washing machine Atlant is deciphered as a malfunction of the Hall sensor of the motor or tachometer.
There are other probable causes of failure, for which the SM gives an error code F9:
- Malfunction of the engine or its contacts with the control unit.
- Faulty control unit.
Before you try to fix the breakdown, we suggest performing simpler steps.
Diagnostics and troubleshooting
The above malfunctions require repair. However, you must first eliminate the system failure. What does it mean? When the control board freezes, the display erroneously shows the code.
To reset the error, do this:
- Disconnect the Atlant washing machine from the mains, wait 15-20 minutes. Now turn it on. If the F9 error no longer lights up on the CMA Atlant display, everything worked out. If the error was not resolved, we continue to search for damage.
- Additionally check the spin button.If she sunk or pinched, it could also cause a malfunction.
Tacho Generator Check
The tachometer measures the speed of rotation or engine speed, made in the form of a metal ring with wires connected to it.
The Hall sensor performs an important function: measuring the speed of movement (voltage), it sends a signal to the control unit. For different washing and spin modes, the rotation speed of the motor needs a different one. For example, for spinning, the speed should increase to 800 rpm.
How can a normal user determine that the tachometer is out of order? Pay attention to the operation of the washing machine. If this part fails, you will notice that:
- The drum sharply changes the speed of rotation.
- With increasing speed (spin), the drum spins slowly.
- Speed too high for the wash program.
- You get wet things after spinning.
Tacho Check
Make sure that the SM Atlant shows the F9 error code due to problems with the tachogenerator.
What to do:
- Disconnect the Atlant power supply by unplugging it.
- Unscrew the bolts securing the back cover of the washer.
- Below is the engine. Remove a belt from it and turn off bolts of fastening of the motor.
- Disconnect the connectors and connections.
When you removed the motor, disconnect the connectors from the Hall sensor, measure the resistance on them with a multimeter. Normal values are approximately 60 ohms.
Set the voltage measurement mode on the multimeter. With the probes attached to the tacho outputs, rotate the engine. The voltage should rise to approximately 0.2 V.
It happens that the tachogenerator is shaken due to the constant shaking of the SM Atlant. Inspect the sensor, tighten if necessary.
Damage to the Hall sensor is very rare. How to fix the situation if no problems are found? Check the wires and connections between the control module and the tachogenerator. Tighten connectors or replace damaged wiring.
If the error F9 on the Atlant washer is highlighted due to a tachogenerator breakdown, he needs a replacement. How to solve a problem:
- Unclench the harnesses and disconnect the sensor wires.
- Remove the protective cover by releasing the latches.
- Remove the screws that secure the device.
- Remove the faulty tachogenerator, install a new one in the reverse order.
Additionally inspect the engine of the Atlant washing machine. After checking and installing, run CM. See if the F9 error has disappeared from the screen.
If you are not sure that you can handle the replacement, contact a service center.
