The clicking sound during drum spinning may be caused by the Door Switch Assembly. The manual states to check for a clicking sound once or twice when the START/PAUSE button is pressed, which indicates normal operation of the Door Switch Assembly. If the Door Switch Assembly is broken or not functioning correctly, it may cause abnormal clicking sounds. In such a case, the Door Switch Assembly should be replaced.
