The Thermador MBBS 01 is a replacement water filter cartridge used in certain Thermador refrigerators. To remove and replace the MBBS 01 water filter, follow these steps: 1. Locate the Water Filter: The MBBS 01 water filter is usually located in the upper right corner of the refrigerator compartment. Look for a small compartment or housing with a filter icon or label. 2. Turn Off the Water Supply: Before removing the water filter, turn off the water supply to the refrigerator. This prevents water from flowing out when you remove the filter. 3. Release the Filter: Depending on your refrigerator model, you may need to push a button, slide a latch, or twist the filter counterclockwise to release it. Follow the instructions provided in your refrigerator's user manual for the correct method to release the filter. 4. Remove the Filter: Once the filter is released, gently pull it out of the filter housing. Dispose of the Old Filter: Properly dispose of the old filter according to local regulations. 5. Install the New Filter: Align the new MBBS 01 water filter with the filter housing and insert it. Follow the manufacturer's instructions to ensure proper installation. 6. Lock or Secure the Filter: If applicable, lock or secure the new filter into place using the provided mechanism. 7. Turn On the Water Supply: After installing the new filter, turn on the water supply to the refrigerator. 8. Flush the Filter (if necessary): Some filters may require flushing with water before use. Check the user manual for any specific flushing instructions. Always consult your refrigerator's user manual for model-specific instructions on removing and replacing the MBBS 01 water filter.
