Minor clumps or sediment appearing after mixing milk powder do not necessarily indicate abnormal heating from your milk warmer. Unlike sugar or salt, which can dissolve instantly, milk powder is a complex blend of protein, fat, carbohydrates, minerals and vitamins. Mixing it involves several stages: wetting, sinking, dispersion, then dissolving or suspending.
We recommend you first follow the instructions printed on your milk powder can for the correct water temperature, water volume and shaking method.
If your device heats normally with no error alerts, and this issue only occurs with one specific milk powder, the problem is most likely related to the powder’s inherent dispersibility.
