Troubleshooting My Philips/Saeco espresso machine's coffee is lukewarm If your Philips/Saeco espresso machine's coffee is not warm enough, read along for some tips and tricks on reaching a higher temperature for your coffee. Change temperature setting in the machine menu (optional) Change temperature setting to High/MAX. This can only be done if your machine has a Menu button. Enter the menu and select temperature. Did you add milk or warm milk frothed milk? Adding cold milk or warm frothed milk to a coffee, in both cases the temperature will decrease to some extent. This is normal behavior. Did you pre-heat the cups? Pre-heat the cups with warm water or use a cup heater. Temperature will decrease when brewing coffee in cold cups. Are you using thick walled cups or a mug? Use thin walled cups. Thick walled cups absorb heat of the coffee which lowers the in-cup coffee temperature. Did the temperature dropped over time? Descale the machine with the Philips/Saeco decalcifier as the internal circuits might be clogged up with scale.
