CODE LE WashTower Series High

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.

⏱ 30-45 Mins Troubleshoot →
CODE nE WashTower Dual Inverter Heat Pump Dryer Series High

Heat Pump Thermistor Disconnect

The nE error indicates an open-circuit fault detected on the heat pump evaporator/condenser thermistor loop. The main PCB detected resistance exceeding threshold limits (>500 kΩ or 0V reference signal), triggering an immediate safety lockout to prevent compressor failure.

CODE d80 WashTower Series (WKEX/WKGX) High

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.

⏱ 30-45 Mins Troubleshoot →
CODE LE WashTower Series Washer High

Locked Motor Rotor Position Error

The LE error indicates a Locked Motor condition where the Main Control Board detects that the direct drive motor cannot turn or fails to receive rotor positional feedback pulses from the Hall sensor (RPS) during operation.

⏱ 30-45 Mins Troubleshoot →
CODE LE WashTower Direct Drive Series High

Direct Drive Motor Locked LE

Error code LE indicates a Locked Motor (Drive Error). The main PCB inverter controller detects that the Direct Drive brushless DC (BLDC) motor rotor is stalled, failing to achieve target RPM, or the Hall-effect rotor position sensor (RPS) feedback signals are missing or erratic.

⏱ 30-45 Mins Troubleshoot →
CODE LE WashTower Series (WKEX200 / WKGX200) High

Locked Motor Rotor Hall Sensor Trip

Error code LE indicates a Locked Motor condition detected by the main control board via the direct drive rotor position sensor (RPS/Hall sensor). This occurs when the tub cannot rotate freely, the Hall sensor fails to report rotational pulses, or an open/short circuit exists in the stator winding harness.

⏱ 30-45 Mins Troubleshoot →
CODE 3C WashTower Series High

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.

⏱ 30-45 Mins Troubleshoot →
CODE Er IF Craft Ice French Door Refrigerator Series High

Ice Fan Motor Failure Er IF

The main PCB failed to detect a feedback pulse signal (FG tachometer reading) from the ice maker compartment blower fan motor (BLDC) within 65-115 seconds of commanded operation, tripping the Er IF protection lock.
