It is sometimes difficult to understand that the washing machine spins the drum in one direction. Usually, after loading the laundry and installing the program, you go on business, and do not stay to enjoy the washing process. How to determine that the drum does not rotate correctly, and is it possible to fix it with your own hands? Let's figure it out together.
Why does the washer spin the drum in one direction?
The normal operation of the equipment is in the programmer. To better rid the laundry of dirt, the machine rotates the drum first in one direction, then, after a pause, in the other. Sometimes the problem does not cause inconvenience, except for poorly washed things, and the washer continues to work in the usual rhythm.
In other situations, the machine may stop and display an error code. This happens in electronically controlled SMA, where the controller is responsible for the operation of all nodes. The system notices a malfunction, and the module signals a shutdown. Thanks to the error, the user can understand where to look for the cause of the problem.
If the drum does not rotate correctly, there are two possible malfunctions:
- Control board problem. Perhaps the contacts or tracks that are responsible for the operation of the motor are burnt. Therefore, it starts work only in one direction. In such cases, the diagnosis and repair of the element is necessary.
- The electrical circuit of the engine is damaged. Again, the motor cannot receive a signal for proper operation. Inspection of the engine circuit is required.
If you suspect such a malfunction, observe the progress of the wash. After withdrawing water, look through the glass hatch to make sure that the rotation does not occur correctly. In vertical washers, the malfunction can be determined as follows:
- Listen for the sound of spins. Between them should be an interval of 1-2 seconds.
- Look at the pulley. To do this, unplug the equipment from the network. Unscrew the screws along the perimeter and remove the side panel. Run the machine. If the pulley rotates only to the right or left - the malfunction is obvious.
Found a malfunction? It’s time to start solving the problem.
Control Module Inspection
Visually check the board at the time of burning and melted elements can be independently. But the repair is better left to the master, because for accurate diagnosis and restoration of the electronic part, professional knowledge will be required.
Here's how to charge a fee:
- Unplug the ACA plug from the outlet.
- Remove the powder dispenser by pressing the latch in the center.
- Remove the bolts securing the panel around the perimeter.
- Press out the latches with a screwdriver and remove the panel from the housing.
- The board can be hidden in a small box or immediately behind the plastic protection.
- Take a picture of all the connections.
- Disable chips one at a time, inspecting all contacts for integrity.
- Check the surface of the element for black fumes.
In machines with vertical loading, it is enough to unscrew the two rear screws to dismantle the panel with the unit or pry off the fixing latches.
If no visual abnormalities are found, assemble the machine and consult a professional. Only he will determine whether the module can be repaired or better replaced.
Check engine wiring
The collector motor is located under the SMA tank behind the rear wall. In Samsung models, the inverter motor is mounted directly to the tank. In any case, you have to remove the back panel.
Working process:
- After disconnecting the machine from the mains, move the housing away from the wall. You should be free to approach the back.
- Now unscrew the screws along the perimeter, lift the panel and put it to the side.
- Inspect the wiring leading to the motor.
- Reconnect the engine chips. Perhaps due to strong vibrations, the mounts are loose.
If burnt parts and damage are found, it is necessary to replace the wire, or better, the entire cable from the module to the motor. Remember that working with electrics is complicated and dangerous. Therefore, if you did not immediately find the cause of the problem, call a specialist.
Even if the equipment does not give an error code, but you notice a malfunction in the usual operation of the washer, do not delay inspection and repair. Sometimes it’s better to fix the problem right away, because replacing the main parts is expensive, not to mention buying a new car. Be carefull!
