Oven interior light does not work and F08 may appear when trying to turn the light on.

Safety: Switch off power and allow the oven to cool before touching the lamp cover.

• Replace bulb: Unscrew the glass lamp cover inside the oven (usually at the rear or side). Remove the bulb and inspect the filament. Replace with the correct high-temperature Ariston oven lamp (typically 25–40 W, E14 or E27 depending on model).
• Check lamp holder: Inspect the ceramic lamp holder for cracks or burning. If damaged, replace the lamp holder assembly.
• Inspect wiring: From the rear of the oven, check the lamp wiring harness for heat damage or loose connectors at the control board.
• Board check: If a known-good bulb and holder do not work and F08 persists, the lamp relay or triac on the control board may be faulty and the board may need replacement.
