How to Fix / Troubleshooting
Safety first: Disconnect power before removing the top or control panel.
- Power reset: Unplug the dryer for at least 5 minutes to allow the control to fully discharge. Plug back in and check if E09 clears.
- Inspect control panel: Remove the top cover to access the control panel and main PCB. Check the ribbon cable or harness between the user interface and main board. Reseat connectors firmly.
- Check for moisture: Look for signs of moisture or detergent residue on the control board or panel. Dry gently with a soft cloth and allow time to air dry.
- Visual inspection: Examine the PCB for burnt components, cracked solder joints, or corrosion. If present, the board likely needs replacement.
- If E09 persists after reseating cables and power reset, the user interface board or main PCB may be defective. Replacement typically requires a technician to ensure correct part selection and safe installation.
