Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Warmer does not turn on. | Not plugged in; power outlet issue; damaged cord/plug. | Ensure warmer is securely plugged into a working outlet. Check for visible damage to cord/plug. |
| Milk is not warm enough. | Incorrect setting selected (e.g., room temp for refrigerated milk); insufficient water in reservoir; mineral buildup. | Verify correct starting temperature and volume settings. Ensure water reservoir is filled. Perform descaling if necessary. |
| Milk is too hot. | Incorrect setting selected (e.g., refrigerated for room temp milk); volume setting too high for actual milk amount. | Verify correct starting temperature and volume settings. Adjust time manually if needed after initial warming. Always test milk temperature before feeding. |
| "Water Error" or similar message. | Low water level in reservoir; sensor obstruction; mineral buildup. | Refill water reservoir to MAX line. Clean the reservoir and warming chamber thoroughly. Perform descaling. |
| Takes too long to warm. | Mineral buildup; very cold starting temperature (e.g., frozen milk). | Perform descaling. Ensure appropriate setting for frozen milk is selected, which naturally takes longer. |
