What to do if LG washing machine malfunctions? Pay attention to signs of damage.
If the SE error code lights up on the washer display, then the SM can take water into the tank normally, however, when you go to the washing program stops, the drum does not spin.
This breakdown is characteristic of direct-drive Al-Ji automatic drive machines, as well as belt-driven washers and a three-phase silent electric motor.
What does SE code mean and why does it appear
It happens that the SE code for the LG washing machine is confused with a 5E error, due to the similarity of electronic characters. Whatever you call it, the fault remains the same.
The error code SE informs the user about problems with the motor. Due to the fact that the motor shaft does not rotate, the drum does not scroll underwear.
However, this malfunction does not always require repair of the washing machine; it happens that you can remove the error yourself and solve the problem.
Why does the code light up
If the Lji washing machine (LG) shows an SE error on the display, the reasons may be:
- Weak connections. It is necessary to check all the connectors that are connected to the motor. It happens that they depart, which means a contact breakdown and signal interruption. Additionally inspect the wiring loop from the motor to the control module. If something is broken, repair or replace the damaged section of the wire.
- A system failure could also cause an error on the display. Disconnect the washing machine by pulling the plug out of the socket (for no more than 20 minutes). After switching on, a reset of the SE error should occur.
If you were unable to remove the error, then you must proceed to repair the parts. Read how to fix the breakdown below.
How to repair
When LG SMA gives an error code SE, then in 90% of cases the reason lies in the breakdown of the tachogenerator (Hall sensor). This device controls the speed of rotation of the drum. Therefore, in case of its malfunction, the drum “does not know” what speed to work with, and the system writes a malfunction code.
Sometimes it happens that the breakdown does not lie in the tachogenerator, but in the combustion of the resistor. Then you need to replace the resistor.
In any case, the tachometer must be checked. It is located below, on the motor shaft.
- Open the rear panel of the machine.
- Remove the belt from the shaft and remove the screws that secure the motor.
- Disconnect the connectors, remove the engine.
- Release the tachogenerator contacts, attach the multimeter probes to them.
- The part is operational with a resistance of about 60 ohms.
- Additionally configure the tester to measure voltage.
- While checking the tachometer, scroll the engine. The norm is considered an indicator of about 0.2 V.
If the Hall sensor is defective, you need to install a new element. What does this mean: with the engine removed, disconnect the tachogenerator wires, remove the cover. The lid can be attached either on latches or on bolts that need to be unscrewed.
Remove the part and install a new one in the reverse order.
What else can cause a breakdown:
- If the motor malfunctions, the SE error lights up on the screen of the LG washing machine; the washing process does not start. How to fix the situation: you will need to change the motor. How to remove the engine from the SM is already described above. Additionally, watch a video on the topic:
- If your washer does not rotate the drum, but writes an SE error, a check of the control unit is required. In case of breakage, it is not difficult to replace the unit. It is more difficult to repair the control board, solder the contacts and strip the tracks, so you can contact the service center.
- With constant vibrations during the spin cycle, inside the LG washing machine, wires and connections may fray or slip. Check the wiring loop from the control unit to the motor.
Before starting work and repairing the machine, do not forget to disconnect it from the network and communications. If the recommendations helped remove the SE error from the display and restored the LG SM to work, then everything was done correctly.
