LG washing machine for parts. Control panel, spider arm, drum, gaskets, internal hoses/clamps, rotor position sensor, door, outside panels all in good shape.
I was told that the spider arm was broken so I disassembled the necessary parts to verify this and found that was not the problem. I also checked the rotor position sensor and it showed 9 ohms which is the correct resistance it should have. Not sure what the exact problem was but I didn’t want to spend money on trying to find out.
