Ok. This is a VERY common problem with LGs and Samsungs and pretty much any machine with the new induction motor direct drive system. It indicates what the main controller believes is a "Locked Rotor" on the induction motor assembly. The part you need to replace is called a Hall effect sensor on the drive motor. Some people even call it the rotor position sensor but regardless, it is part # XXXXX for your machine and will cost $17.49 from Sears, may be cheaper from YOUR favorite local appliance
part supplier using the same part number.It can ALSO be ordered directly from LG but believe me, they are slower than Sears and MAY charge more for the part than Sears does!
It is VERY easy to install by removing the rear cover of the washer, removing the motor's rotor assembly (k360 in diagram) , then the stator (k350) , then flipping that stator over and installing the part (k351) . VERY RARELY is it anything else causing this error, but sometimes an open coil on the stator or a failed control board can cause this, however once again, I must stress that this is EXTREMELY UNLIKELY
. A new stator will cost you MUCH more and will have a new sensor
, and therfore will fix the problem, but at nearly ten times the cost for the same problem. Please try the Hall effect sensor first and your problem WILL be solved. If it is not, we can explore other options. Please let me know if you need further information.
