LG washing machines displaying error code SE are indicating a “motor fault” although the technical information also says it could be a main PCB fault. They recommend to, “try the motor first”.
Like many error codes it’s vague and not too helpful, especially for a DIY repairer. So you really need an engineer to try and sort this one. You can’t possibly justify “trying the motor first” if you interpret that as buying and fitting a new motor. They are way too expensive to gamble on. You need to at least know how to test a motor for faults and check its connections and carbon brushes (if fitted) if you want to try and diagnose the cause. I have some general advice on troubleshooting washing machine motor not running but an engineer would be best.

I’m a technician, and the machine I’m presently working on now is showing SE, I have check it is not the motor, bit from the PCB. pls what can be the reason for this fault from the PCB? what can I check for on the board. I really need your help.
If you’ve managed to sort it Kenneth please let us know. Unfortunately there’s no information available at all about the pcbs as manufacturers don’t want us repairing them. If it’s definitely not the motor the suspicion falls on the pcb or connections but if you don;t have another one to try it’s a gamble buying one. You could always try getting it tested at QER repairs.
