Microwave displays E15; the interior light may flash or flicker when starting.

Safety: Unplug the microwave before replacing the lamp. Do not remove the outer cabinet unless the design and manual explicitly allow user lamp replacement.

User checks (if a lamp access panel is provided):

• Locate the lamp access cover (often on the side or top of built-in models) as described in the SMEG manual.
• Remove the cover and inspect the lamp. If the filament is visibly broken or the bulb is blackened, it is likely blown.
• Replace it with the exact type and wattage specified by SMEG, ensuring it is suitable for microwave use.

After replacement:

• Reinstall the cover securely before plugging the unit back in.
• Test by opening/closing the door and starting a short cycle.

If E15 persists:

• The lamp holder, wiring, or control PCB may be faulty and should be checked by a technician.
