Washer-dryer combo displays E10 and will not start; control panel may be unresponsive or partially functional.

Safety first: Unplug the appliance before removing the top or control panel.

• Power reset: Leave the unit unplugged for 5–10 minutes to allow capacitors to discharge, then plug back in and try again. This can clear transient communication faults.
• Inspect control connections: Remove the top panel and access the control console. Check ribbon cables and connectors between the user interface and main PCB. Reseat all connectors firmly.
• Check for moisture: Look for signs of condensation or water drips on the control boards. If present, dry the area thoroughly and identify the source of moisture (e.g., leaking dispenser or vent) for repair.
• Board replacement: If E10 persists and wiring is intact, either the UI board or main control board may be defective. Replacement should be done with the correct Avanti part numbers and may require programming; consider professional service.
