Air fryer shows E8 and will not start; sometimes appears after a power surge or outage.

Safety first: Unplug the unit before any inspection.

• Power reset: Unplug the air fryer for at least 15 minutes to allow internal capacitors to discharge. Plug back in and test. This can clear transient memory errors.
• Try a different outlet: Plug the unit into a known‑good outlet without extension cords or power strips. Poor power quality can trigger control errors.
• Inspect the control panel: Check for signs of moisture ingress (condensation, spills) around the display and buttons. If moisture is present, allow the unit to dry in a warm, dry room for 24 hours before retesting.
• Internal inspection (advanced): Remove the housing and inspect the main control board for burn marks, cracked components, or bulging capacitors. Any visible damage usually means the board must be replaced.
• Firmware: Some Instant Pot air fryer models may support firmware updates via the manufacturer. Check the user manual or support site; if an update is available, follow their instructions.

If E8 persists after resets and drying, replacement of the main control board is typically required.
