Oven emits a strong electrical or plastic burning smell when first used or after a repair.

Safety first: If the smell is very strong or accompanied by smoke, switch off power and inspect before further use.

Step-by-step checks:

• 1. Initial burn-in: For a new Zanussi oven or a new element, run it empty at 200–250°C for 30–60 minutes with good ventilation. Some smell is normal initially.
• 2. Remove packing: Ensure all plastic films, cable ties, and cardboard spacers have been removed from inside and around the oven.
• 3. Inspect wiring routing: Check that harnesses are clipped away from elements and are not touching the cavity.
• 4. Check for melting: Look for discolored or deformed plastic parts near hot areas. Replace any damaged components.

Warning: Do not ignore persistent plastic burning smells; this can indicate a serious overheating issue.
