Error F7 in the Atlant washing machine
What to do if the automatic machine refuses to turn on or start washing? In this case, the display shows fault code F7, and on models not equipped with a display, the second, third and fourth indicators light up. Let's figure out what the probable causes of such a breakdown are and what actions should be taken.
Priority actions
In some cases, the washing machine may not turn on at all. In others, the control panel is still activated, but it will not be possible to start the desired washing program. Error F7 on the Atlant machine indicates problems with the electricity supply, insufficient voltage in the network. What to do next after decrypting the code?
You can try to reset error F7 by restarting the Atlant washing machine.
Therefore, first, unplug the plug and leave the “home assistant” for 20-30 minutes. After this time has passed, try turning on the machine again. The error code may disappear as suddenly as it appeared. If this does not help, follow these steps.
- First, check the power grid. For the washing machine to work, the voltage must reach 220 V. What can a housewife do who does not have special equipment? Take any household appliance, for example, an electric kettle. If it functions properly, then there are no problems with the power supply. It doesn’t work – therefore, there is not enough voltage. Perhaps the reason for this is an excessive load on the network; this happens when several pieces of equipment are working in an apartment at the same time. You can wait until the readings are restored or call an electrician to diagnose the network.
- Secondly, inspect the extension cord if the washer is connected to the electrical outlet in this way. The test is carried out in the same way - any other device is plugged into the connector where the power cord of the machine is inserted. If it doesn't work either, the problem is in the extension cord.
- Thirdly, ring the power cord of the machine. You can start with a visual inspection of the cable. You will probably find some defects or traces of melting on its surface. If there are no visual flaws, use a multimeter and test each of the three cord wires in turn. If a breakdown is detected, replace the element.
These are the immediate actions that should be taken when you see error code F7 on the display. If the problem isn't a power outage, broken extension cord, or faulty power cord, you'll have to dig deeper. Let's figure out how to fix an automatic machine.
Checking and replacing the interference filter
Atlant washing machines are equipped with a capacitor that protects equipment from power surges in the network. The noise filter copes only with small differences. Having felt a strong impulse, the capacitor will burn out, and in the worst case, the control module of the machine will also fail.
To protect your automatic washing machine from breakdowns, it is better to install an additional network voltage stabilizer in your apartment.
How to check the interference filter of an Atlant washing machine?
- Turn off the power to the machine.
- Unscrew the bolts securing the “top” of the washer and remove the cover.
- Find the capacitor, it is located on top.
- Inspect the power filter for swelling or carbon deposits.
- Remove the back panel of the case.
- Disconnect the wiring leading to the capacitor.
- Remove the surge protector from the machine.
- Place the multimeter probes on the element contacts.
- Measure the capacitor voltage at the input and output.
If there is no voltage at the output, the noise filter is no longer functioning. The device cannot be repaired; the capacitor will have to be replaced. If this is not the case, it is necessary to diagnose the control board.
Control module diagnostics
What to do if, after all attempts to repair the equipment, the machine stubbornly displays error code F7 on the display? Most likely, the worst happened - the main unit, the “brain” of the machine, was damaged. It is better to entrust the inspection and repair of the control board to specialists; it is not recommended to get into the electronics of the washing machine on your own without the necessary knowledge and skills.
A malfunction of the washing machine can be caused by a violation of the soldering of the diodes on the board, burnout of resistors and other small elements. To carry out diagnostics, you will definitely need a multimeter. For repairs you will need a soldering iron, rosin, and solder.
The following components of the main control module may have failed:
- capacitor. If the element is swollen, you can replace it without calling the tester. In other cases, the part is checked with a multimeter. When reinstalling a capacitor, you should take into account its polarity;
- resistors. They are checked in two stages. First - first order elements with a resistance of 8 Ohms and up to 2 Amperes. After that - at 10 Ohms and up to 5 Amps. If indicators do not comply with the standards, you will have to replace the board components;
- thyristor block. First order diodes are tested with a multimeter. The voltage value should not exceed 20 Volts.
Repairing the control board is a complex and painstaking job. Its implementation requires knowledge and experience. In order not to damage the washer even more, it is better to entrust the diagnosis to professionals.
