Electric oven shows E70, and the interior light does not work; some functions may be disabled.

Safety first: Disconnect the mains power before replacing the lamp or accessing switches.

• Replace lamp: Remove the glass cover over the oven bulb (usually by twisting). Replace the bulb with the exact type and wattage specified by Amica (typically a high-temperature E14 oven lamp).
• Inspect lamp holder: Check the lamp holder for signs of burning or looseness. Replace the oven lamp holder if damaged.
• Door switch check: Locate the oven door switch (usually near the door frame). Press it manually and listen for a click. Test continuity with a multimeter; replace if faulty.
• Control board: If the lamp and switch are good but E70 persists, the electronic control board may misread the door/lamp circuit and require replacement.
• Test: After repairs, restore power and verify that the lamp operates and E70 is cleared.
