F6 E0 – Lost communication errors

An F6 E0 error usually means the data connection between the oven’s control board and the display console has been lost. Here’s how you can restore communication:

3. Check that the P6 connector on the control board and the P2 connector on the display are fully plugged in. Push in firmly if needed.
4. Inspect the wiring between pins 1, 2, 4, and 5 on P6 and P2. Check for continuity with a multimeter.
5. If the wiring is damaged, replace the oven’s wiring harness. If the wiring is intact and the error code is still showing up, replace the control board.
6. Restore power to the oven.
