Possible Causes

Defective motor control triac on PCB, Shorted motor windings, Faulty tachometer feedback, Damaged motor harness

How to Fix / Troubleshooting

Safety first: Unplug the washer before accessing the motor or control board.

  • 1. Check mechanical drive: Confirm the belt is intact and the drum turns freely by hand. If mechanical parts are fine, focus on the motor and electronics.
  • 2. Inspect motor and harness: Remove the rear panel, disconnect the motor plug, and inspect for burnt pins or melted plastic. Check the harness for damage.
  • 3. Test motor: Use a multimeter to measure motor winding resistance and tachometer coil resistance. Compare to Amica service data. Replace the motor if readings are out of range.
  • 4. Examine PCB: Remove the top cover and inspect the main control module for burnt components near the motor triac or relay. If visible damage is present, replace the PCB.
  • 5. Professional repair: Because E21 often indicates an electronic drive failure, board-level repair is best handled by a qualified technician.
