Motor  Locked  Error  (LE)

[Pre  Check]
‡ Gentle  wash  cycles,  such  as  Perm  Press,  Delicates,  Hand  Wash,  and  Wool/Silk  should  only  be  used  for  smaller  loads.

Because  these  cycles  are  more  gentle  in  tumbling  and  spinning,  putting  too  much  in  the  drum  can  register  an  issue
with  the  motor.  Remove  items,  reset  unit  and  test  with  a  Rinse/Spin  cycle.

‡ Don’t  replace  the  PCB,  when  the  hall  sensor  is  replaced.

Replace  the  PCB,  when  the  LE  is  displayed  after  replacing  the  hall  sensor.
