The meaning of the SE error code in LG washing machine by MyApplianceRepairHouston.COM

Sometimes users confuse the SE code of LG washing machine with the 5E fault. Indeed, it happens due to the similarity of electronic symbols. So, no matter how you call it, the malfunction remains the same.

The SE error code informs a user of a motor problem. Due to the fact that the motor shaft does not rotate, the drum does not spin the laundry.

However, this malfunction not always requires repair. Sometimes you can reset the error and solve the problem.

Why does the code light up

If LG washing machine shows the SE error on the display, the reasons may be:

If you fail to remove the error, then you need to start repairing the parts.

How to carry out repair works by MyApplianceRepairHouston.COM

When LG washing machine gives the SE error code, in 90% of cases the reason lies in the failure of the tachogenerator (Hall sensor). This device monitors the speed of drum rotation. Therefore, in case of a malfunction, the drum “does not know” how fast to work, and the system issues a trouble code.

Sometimes it turns out that the failure doesn’t refer to the tachogenerator. It is about the resistor’s burning out.

Then you need to replace the resistor. In any case, you need to check the device. Find it below, on the shaft of the engine.

  1. Open the back cover of the washing machine.
  2. Remove the belt from the shaft and remove the screws fastening the motor.
  3. Disconnect the joints, remove the engine.
  4. Release the contacts of the tachogenerator, attach the multimeter probes to them.
  5. The part is OK if the resistance is about 60 Ohm.
  6. Additionally, configure the voltage tester.
  7. Checking the tacho sensor, scroll the engine. The norm is about 0.2 V.

If the Hall sensor is faulty, you need to install a new element.

  1. With the removed engine, disconnect the tachogenerator wires.
  2. Remove the cover. The lid can be fastened on latches or on bolts that you have to unscrew.
  3. Remove the part and install the new one in the reverse order.

What else can cause a breakdown:

Before starting work and repairing the appliance by MyApplianceRepairHouston.COM, do not forget to disconnect it from the network and communications. If the recommendations helped to remove the SE error from the display and the washing machine LG was restored, it means everything was done correctly.
