I really like my direct drive LG washing machine, but it recently gave me an LE Error. I thought, well maybe it's the drum or something stopping the motor. The drum would jerk, make about a half a revolution then stop and make the jerking motion again.
After much research, and disassembling the motor 3 times ; I figured I would give the hall sensor a test on my bench. This involved removing the black rubber from the top of circuit board , carefully as to not damage the SMD components on the PCB.
After testing, I found that the two center resistors (681), or 680ohm were not giving me any reading on my meter. So, I simply soldered a couple onto the board in line with the old ones; and it worked. Because this sensor is waterproofed, I decided to purchase a replacement anyway ; and used my fixed sensor whilst I waited for the replacement part.
I think this is worth mentioning because these hall sensors fail a high percentage of the time with the LG LE Error ; and it's literally a couple of bad resistors (most are the end two, not the ones in the middle of the circuit) ... so if you run into this problem with your LG , try testing the resistors and maybe replace them for immediate continued operation. I thought of sealing the old PCB up and using it, but really this was a part failure investigation.
