•
•
Gentle wash cycles, such as Perm Press, Delicates, Hand Wash, and Wool/S ilk 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. R emove items, reset unit and test with a R inse/S pin cycle.
•
Don’t replace the PCB, when the hall sensor is replaced.
