Clock/timer cannot be set, oven will not start cooking, error appears when pressing start

Safety first: No internal work is required for basic reset, but disconnect power if removing panels.

• Initialize clock: Many Etna ovens require the time to be set before any heating function will operate. Press the clock button and use the +/- or rotary selector to set the correct time, then confirm as per the user manual.
• Reset control: Disconnect the oven from mains for 2–3 minutes to reset the electronics. Restore power and attempt to set the clock again.
• Check buttons: If certain keys do not respond, the touch panel or button PCB may be faulty. Inspect for stuck or damaged buttons and replace the user interface board if necessary.
• Firmware issue: If the error persists after reset and the UI board is known good, the main PCB may have corrupted firmware. Replacement of the main PCB is usually required.
