EA — Motor position / clutch error

The control couldn't detect the motor's rotor position at startup or during a phase transition. Often a hall sensor problem or a stuck clutch/coupling on direct-drive top-loaders.

How to fix it

  1. Unplug for 5 minutes and try a Rinse+Spin with the drum empty.
  2. Remove the rear/back panel and inspect the rotor and stator for cracks, dust, or rub marks.
  3. On top-loaders, listen for the shifter solenoid clicking when the cycle starts — replace shifter if silent.
  4. Test the hall sensor harness and replace the hall sensor if reseating doesn't help.
  5. If parts test good, replace the inverter PCB.

Why it happens

Typical signs: Drum doesn't agitate or spin · Loud buzz at start · Code appears within seconds of pressing Start

  • Failed hall sensor Same root cause as Sr/3E — position feedback missing.
  • Stuck mode-shifter / clutch (top-load) Direct-drive shifter doesn't engage spin vs wash mode.
  • Damaged rotor magnets Rotor fractured from a hard load impact.
  • Failed inverter PCB Cannot commutate the BLDC motor.
