Washer-dryer combo shows E15; unit may not respond correctly to button presses or display may flicker.

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

• Power cycle: Disconnect power for 5 minutes, then reconnect and test the controls. Sometimes a reset clears temporary communication faults.
• Dry the panel: If the panel was exposed to steam or spills, allow it to dry completely. Do not spray cleaners directly onto the control panel.
• Inspect ribbon cable: Remove the control console and check the flat ribbon cable between the user interface board and main PCB. Re-seat both ends carefully.
• Check for corrosion: Look for signs of moisture damage or corrosion on the UI board. If present, the panel may need replacement.
• Replace control panel: If E15 persists and wiring is intact, replace the user interface/control panel assembly with a compatible NewAir part. If the issue remains, the main control board may also require replacement.
