Common Operational Issues

• Oven not heating: Check circuit breaker (240V), verify temperature sensor, inspect heating elements.
• Uneven baking: Preheat fully (especially convection models); use correct rack position.
• Door not closing properly: Check hinges and door alignment; clean door gasket.
• Self-Clean not working: Door must be fully closed and locked; oven must be cool to start.
• Steam oven issues: Check water tank level and descale regularly.

Maintenance Tips

• Self-Clean mode: Remove racks and accessories before running.
• Descaling (Steam models): Use Bosch descaling solution every 3–6 months.
• Regular cleaning: Wipe interior after each use; clean door glass with non-abrasive cleaner.

Safety note: Always disconnect power before servicing heating elements or sensors. Allow oven to cool completely before performing self-clean or manual cleaning.
