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.
