Tecnogas range shows E8 and the clock or timer cannot be set; oven functions may be disabled.

Safety first: Turn off power at the breaker before removing the control panel.

Steps:

• Power cycle: Disconnect power for at least 10 minutes to allow capacitors to discharge. Restore power and attempt to set the clock again.
• Check supply voltage: Ensure the range is connected to a stable power source with correct voltage (per Tecnogas rating plate). Undervoltage can cause clock errors.
• Inspect control board: Remove the rear cover and visually inspect the EOC for burnt components or bulging capacitors.

If E8 returns after a proper reset and supply is correct, the control board’s memory or clock circuit is likely damaged and the EOC should be replaced.
