E8 error code appears intermittently, often when selecting or changing temperature or time.

Safety first: Unplug the air fryer before removing the control panel or front fascia. Capacitors on the PCB can retain charge briefly; avoid touching exposed solder pads.

• Dry out moisture: If the panel was recently cleaned with liquid, leave the unit unplugged for 24 hours in a dry room to allow moisture to evaporate. Do not use a hair dryer or heat gun directly on the panel.
• Inspect the ribbon cable: Remove the screws securing the front control panel. Carefully tilt it forward to expose the flat ribbon cable or plug connecting it to the main PCB. Ensure the connector is fully seated and the locking tab (if present) is engaged.
• Check for damage: Look for kinks, cracks, or corrosion on the ribbon. If any traces appear broken, the touch panel assembly should be replaced.
• Clean contacts: If the connector pins are slightly oxidized, gently clean with a dry, lint‑free cloth. Do not use abrasive materials.
• Reassemble and test: Refit the panel and screws before reconnecting power. Test all buttons. If some keys are unresponsive and E8 persists, the touch panel or main PCB may need replacement.

Do not spray cleaner directly onto the control panel; apply it to a cloth first to prevent future moisture ingress.
