Microwave interior accumulates heavy condensation or water droplets during normal use.

Safety: Condensation itself is not dangerous, but can lead to corrosion if not managed.

• Ventilate: After cooking, leave the door open for several minutes to allow moisture to escape.
• Check vents: Ensure external vents and filters (on over-the-range Bosch models) are clean and unobstructed.
• Wipe down: Regularly wipe moisture from the cavity walls and door to prevent rust.

If excessive condensation persists despite good ventilation: Have a Bosch technician inspect the venting path and cavity condition.
