Hi All! I have been a lurker but thought I would add my fix to this topic... It may be a dated post but very relevant to my wife
After replacing the Hall Sensor to no avail... I was running diagnostics per this post and after placing the machine in a spin cycle I "CAREFULLY" reached into the back and began to rotate the drum. I turned it about eight inches and I heard a "click" and the drum took off on its own. I am assuming that a magnet had to pass the sensor once replaced. I let it spin and now it is running loads perfectly.
