Safety first: Disconnect power and allow the appliance to cool before opening.

Steps to troubleshoot E6:

Check for obstructions: Look through the rear or top grill to see if any foreign objects are blocking the fan. Do not insert metal tools through the grill.
Access fan assembly: Remove the outer housing and internal shroud to reach the convection fan motor and blade. Manually spin the fan; it should rotate freely without scraping.
Inspect wiring: Verify the fan motor connector is fully seated on the control PCB and that the wires are not pinched or burned.
Test motor: With the motor disconnected, measure its resistance. An open circuit or very high resistance indicates a failed motor. If safe and you are experienced, you can briefly power the motor with the correct mains voltage through an isolation device to confirm operation.
Replace components: Replace a seized or open convection fan motor. If the motor tests good but E6 persists and the fan never receives voltage, the main control PCB is likely faulty.

Display shows E6 and the fan does not run; no hot air circulation.
