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

Safety first: Disconnect power before accessing the control panel or main PCB. Avoid touching exposed circuitry with wet hands.

• Power reset: Unplug the unit for at least 5 minutes to discharge internal capacitors. Plug back in and attempt to start a basic cycle.
• Check outlet and voltage: Verify the wall outlet is delivering correct voltage and is not shared with heavy loads that may cause drops. Avoid using extension cords.
• Inspect control connections: Remove the top panel and control console. Check that all wiring harnesses to the main PCB and user interface board are firmly seated and free of corrosion or burn marks.
• Look for visible PCB damage: Examine the main board for burnt components, cracked solder joints, or moisture damage. If present, the board will likely need replacement.
• Replace main control board: If E10 persists and wiring is intact, replace the main PCB with a compatible NewAir control board. Transfer any jumper settings as per the service documentation. This repair is best performed by a qualified technician.
