Re: lg wd12126rd
hall sensor is part of the direct drive motor – you need to remove direct drive of to access it .. its just clips on , in my experience this fault can be direct drive motor itself – comes with hall sensor if you order it , fault can also be down to pcb .
if you take the hall sensor off there will be an lg part number on it ,
there not to expensive so maybe worth a try
just checked connect their about £10
