Oven displays E14, and the interior light may not function correctly.

Safety first: Disconnect the mains power and allow the oven to cool before touching the lamp area.

• Replace lamp: Remove the glass lamp cover inside the cavity (usually twists off). Replace the bulb with a high-temperature oven lamp of the correct wattage and fitting (e.g., E14, 25W).
• Inspect lamp holder: Check for signs of burning or cracking on the lamp holder. If damaged, replace the lamp holder assembly.
• Check wiring: From the rear, inspect the lamp wiring for heat damage or loose connections.
• Test operation: Restore power and test the light button or door-activated light. If the new lamp does not work and the wiring is intact, the control PCB lamp circuit might be faulty and require replacement.
