Step-by-step resolution manuals and root cause matrices
Washer Drum Motor Lock Error
Error code LE indicates a motor lock condition. The main controller detects that the direct-drive brushless DC (BLDC) motor rotor has stalled, the Hall/RPS sensor has failed to report rotation pulses, or an overcurrent state has occurred in the inverter drive.
Exhaust Duct 80% Blockage
The Flow Sense™ system detected an 80% to 89% airflow restriction in the external exhaust vent system, causing excessive thermal buildup that risks tripping the high-limit thermal cutout switch.
Washer Drum Motor Overload Stalling
Error code 3C indicates an Inverter Direct Drive (DD) motor overload condition. The main inverter control board detects excessive electrical current, abnormal rotor resistance, or a failure in motor commutation feedback, initiating an automatic shutdown to prevent thermal runaway or IPM burnout.
