What to do if the Atlant washing machine does not turn on or does not start washing? The error code F7 can be displayed on the board, and on models without a screen, the 2nd, 3rd and 4th indicators are lit.
For SM Atlant, error F7 stands for a problem with electricity or incorrect indicators of the electrical network.
To understand how to fix the malfunction, we will look for the causes of the breakdown.
Causes and troubleshooting
When you turn on the washing machine Atlant gives an error code F7. There are situations when the washing machine does not turn on at all. What do these signs mean?
To solve the problem, do the following:
- Check mains voltage. For normal operation of the SMA Atlant, the voltage must be at least 220 volts. How to check it at home? Plug any household appliance into a power outlet. If it functions as usual, then everything is in order. Does not work - voltage is not enough.
This can happen when the network load is excessive. In this case, you can wait, or you can call an electrician to clarify the circumstances. - Ring the power cord. You need to start with a visual inspection of the cord. Perhaps he was damaged somewhere, melted. If there are no obvious signs of a malfunction, use a multimeter: alternately ring all 3 wires of the cord. In the event of a malfunction, the power cord must be replaced.
- Extension cord check. It is recommended that you connect the Atlant washing machine directly to a power outlet, but not everyone has this option. Connect any household appliance to the extension cord connector into which the washer is connected.
Does the appliance not work? So it's time to change the extension cord.
If SM Atlant turns on, but does not start the wash, how to fix the situation?
Try to clear the F7 error by rebooting. Unplug the plug for 15-20 minutes, then turn it on. Did the error go away? Congratulations, everything worked out. If F7 is displayed again, go to the next step.
Breakdown search and repair
Atlant washing machines provide protection against drops in the network. This function is performed by the power cord element - interference filter (capacitor).
The device protects the control board of the washing machine from damage. Unfortunately, the filter can only handle small power surges. With strong pulses, the capacitor burns out - and it is good if the control module does not suffer.
The user can protect his Atlant washing machine from network swings. You need to install a voltage regulator.
You need to check the condition of the filter, or replace it. What does it mean:
- Disconnect SM Atlant from a network.
- Having unscrewed the screws on the back, remove the top panel of the machine.
- At the top you will see a capacitor (look for a similar part, as in the photo).
- Inspect the filter at the time of burning, bloating, and the formation of fluid underneath.
- Remove the mounting screws on the rear panel.
- Disconnect the electrical connectors, remove the capacitor.
- Connect the probes of the tester (multimeter) to the contacts of the filter.
- Measure input and output voltage.
- If it is not at the output, the device is defective and needs to be replaced.
The new item is installed in the reverse order. The video shows how to replace:
If after checking the error F7 again displays on the display of the Atlant washing machine, most likely the control board element is damaged.
You can call the electronics with a multimeter at home, but it is better to entrust the repair and replacement to the master.
