How to Fix / Troubleshooting

Safety first: Unplug the washer and discharge any capacitors on the inverter board before handling.

  • Inspect motor: Check for burning smell or visible damage. Measure winding resistance; a very low reading may indicate a short.
  • Check wiring: Inspect the harness between motor and inverter for chafing or contact with sharp metal edges.
  • Inverter board: Examine for burnt components or tracks. Replacement of the inverter/control board is usually required if a power device has failed.
  • Professional repair: Due to high voltages and complexity, this repair is best performed by a qualified technician.
