5. Setup
Before first use, wash all components (except the base unit) in warm soapy water, rinse thoroughly, and allow to air dry. The base unit should be wiped with a damp cloth.
- Place the base unit on a flat, stable, heat-resistant surface.
- Pour distilled water into the heating plate reservoir in the base unit. Do not exceed the maximum fill line.
- Assemble the desired configuration of bins and trays (refer to Section 7 for options).
- Place clean items to be sterilized into the bins and trays, ensuring they are arranged to allow steam circulation.
- Place the lid securely on top of the assembled unit.
- Plug the power cord into a suitable electrical outlet.
6. Operating Instructions
Once the unit is set up and plugged in:
- Press the power button to turn on the unit.
- Select the desired sterilization cycle (e.g., 30 minutes, 45 minutes, 60 minutes if applicable, or a standard steam cycle). The unit will typically have a single on/off button for the standard steam cycle.
- The sterilization process will begin, indicated by a light or digital display.
- Once the cycle is complete, the unit will automatically shut off.
- Allow the unit to cool down for several minutes before carefully removing the lid. Be aware of residual hot steam.
- Items will remain sterile for up to 48 hours if the lid remains unopened.
7. Modular Configurations
The Baby Brezza 4-in-1 Sterilizer offers versatile configurations to meet diverse needs:

- Configuration 1 (Full Capacity): Use the lower bin for short bottles, the upper bin for pump parts and nipples, and the accessory tray for small items.
- Configuration 2 (Tall Bottles): Use the lower bin for tall bottles, the upper bin for pump parts and nipples, without the accessory tray.
- Configuration 3 (Short Bottles & Accessories): Use the lower bin for short bottles, and the accessory tray for pump parts and nipples, without the upper bin.
- Configuration 4 (Small Items Only): Use only the upper bin for pump parts or nipples, without the lower bin or accessory tray.

8. Cleaning and Maintenance
Regular cleaning and maintenance are crucial for optimal performance and longevity of your sterilizer.
- Daily Cleaning: After each use, unplug the unit and allow it to cool. Wash the lid, bins, trays, and posts in hot soapy water. Do not use a dishwasher, as high heat can damage components.
- Base Unit: Use a damp cloth to clean the base and control panel. Avoid immersing the base in water to prevent damage to electronics.
- Descaling: Mineral scale can build up on the stainless steel heating plate over time. We recommend using Baby Brezza Descaler or white distilled vinegar monthly to remove buildup. This extends the appliance's useful life. Using distilled water for sterilization also helps prevent buildup.
9. Troubleshooting
If you encounter issues with your sterilizer, refer to the following common solutions:
- Unit Not Turning On: Ensure the power cord is securely plugged into a working outlet. Check for any visible damage to the cord or plug.
- Sterilization Cycle Not Starting: Verify that the lid is properly seated and the unit is assembled correctly. Ensure sufficient water is in the reservoir.
- Excessive Mineral Buildup: Perform a descaling cycle as described in the Cleaning and Maintenance section. Always use distilled water for sterilization.
- Items Not Fully Sterilized: Ensure items are arranged to allow steam to circulate freely. Do not overload the unit.
