Operating Your Dryer
To operate your Bosch dryer, follow these steps:
- Load Laundry: Ensure the lint filter is clean. Load laundry into the drum, making sure not to overfill. Close the door securely until it clicks.
- Select Program: Rotate the program selector to choose the desired drying program based on your laundry type and desired dryness. Consult the program selection table for guidance.
- Adjust Settings (Optional): You can select additional options like Low Heat or Wrinkle Block if needed.
- Start Cycle: Press the Start/Pause button. The indicator lamp will light up, and the cycle will begin. The display will show the estimated remaining time.
- Monitor Cycle: The dryer uses sensors to monitor moisture and will end the cycle automatically when the selected dryness level is reached. The drum may rotate periodically to prevent creasing.
- Remove Laundry: Once the program ends, open the door, remove the laundry, and turn the program selector to Off. Clean the lint filter after each use.
Refer to the manual for detailed instructions on program selection, options, and maintenance.
