In washing machines Atlant there is a system of self-diagnostics: having found out a malfunction in knots and details, it shows on the display a certain error code. If the error on the scoreboard of the SM Atlanta is F4, then there are problems with the discharge of water.
On the models of the washers without the screen, the second indicator will light up. In this case, the machine does not drain the water when necessary. What to do in this case?
What does F4 error mean: the causes and diagnostics of the failure
When F4 error in the Atlant washing machine, in most cases there are problems with the pump (drain pump). However, before disassembling the styralka in search of a malfunction, exclude a system crash.
To reset the F4 error, disable the ATA from the network for 20 minutes, then turn it back on. Look at the display - the error is gone? Then the cause of the malfunction is eliminated.
If the fault code is again displayed, it is necessary to search for the fault. How to fix the situation and solve the problem, read below.
Possible problems and their elimination
Start checking the items:
- Drain hose. Stiralka can not drain the water if there is an inflection or blockage of the hose. Disconnect it from the system, wash under the tap.
- Drain strainer. Following the hose, the pump filter is checked. Usually it is located on the front panel, behind the hatch. Remove the filter and clean it of debris.
- Impeller. While the filter is not in place, check the impeller of the pump. To do this, light in the hole where the filter is installed, and see if the impeller turns. If it stands without moving, then some object hinders rotation. The interference must be eliminated by removing the pump and disassembling it.
- Water pump. It is necessary to inspect the pump at the time of damage or blockage. Check the integrity of the winding.
- Control block. Be sure to check the wiring harness that leads from the pump to the board. The broken wires must either be isolated or replaced. Lastly, the control card is inspected at the time of failure.
Checking and replacing the pump
How to fix the malfunction if the washing machine Atlas gives an error F4? It is necessary to check the drain pump. What this means, we will consider below.
- Disconnect the Stiralk from the network and the communications.
- Put CM Atlanta on its side.
- The drain pump is located below.
- Remove the two fastening screws.
- Remove the pump.
After removal, inspect the impeller. Perhaps, around her thread, which prevents it from rotating normally. Remove the foreign item.
How to check the pump with a multimeter:
- Unscrew the bolts that secure the pump to the snail.
- Measure the resistance of the winding.
- Attach the tester probes to the pump terminals.
- If the multimeter does not show anything, the item is defective.

Replace the new part, secure the fixing screws.
Other malfunctions
The reason for the problems with the drain and F4 errors on the Atlant washing machine may be the control board. If the moisture or short circuit breaks down, the module elements fail. Each element is responsible for the work of some detail.
Taking out the module from SM Atlant, visually inspect it. On the board itself, burnt tracks, broken contacts can be found. If after inspection no problems are found, call each element of the board with a multimeter.
Have you found a malfunction? You can contact the service center or try your hand at it.
Warning, repair the control module is not easy. To solve the problem you will need a block diagram, skills of working with a soldering iron. Therefore, think carefully before repairing the module in the Atlant washing machine to remove the F4 error.
