The Baby's Brew warmer uses slow-heat technology to preserve nutrients and prevent hot spots.
- Ensure the warmer is charged and a bottle containing breastmilk or formula is securely attached.

5. Maintenance and Cleaning
Regular cleaning ensures hygiene and extends the life of your warmer.
- Warmer Unit: The main warmer unit is not dishwasher safe. Do not immerse it in water. Wipe the exterior with a damp cloth. For the heating plate, use a damp cloth or sponge with mild soap, being careful to avoid getting water into the charging port or other electrical components.
- Adapters and Gaskets: Adapters and silicone gaskets/rings can be washed with warm soapy water and rinsed thoroughly. Ensure they are completely dry before reassembly.
- Storage: Store the warmer in a clean, dry place when not in use.
6. Troubleshooting
If you encounter issues with your Baby's Brew Portable Bottle Warmer Pro, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Warmer not turning on. | Low battery. | Charge the warmer fully using the provided USB-C cable and a 2.4A/3A charging block. |
| Milk is leaking from the connection. | Silicone gasket/ring improperly seated or missing; bottle/adapter not tightened sufficiently; incorrect adapter used. | Ensure the silicone gasket/ring is correctly inserted (try flipping it if issues persist). Tighten the bottle/adapter firmly but do not overtighten. Verify you are using the correct adapter for your bottle type. |
| Milk is warming too slowly. | Large volume of milk; milk starting from a very cold temperature; low battery. | Warming time increases with milk volume and colder starting temperatures. Ensure the warmer is fully charged. |
| Display shows an error code. | Internal malfunction. | Turn off the warmer, wait a few minutes, and turn it back on. If the error persists, contact customer support. |
