How to fix it

  1. Unplug and tip the washer back.
  2. Reseat the small tach connector at the rear of the motor.
  3. Measure tach coil resistance — typically 60 to 150 ohms.
  4. Replace the motor if the tach coil is open.
  5. Replace the motor control board if tach reads fine but code returns.
