Troubleshooting My Philips/Saeco espresso machine's coffee is lukewarm If your Philips/Saeco espresso machine's coffee is not warm enough, continue reading for some tips and tricks for hotter coffee. Change the temperature setting in the machine menu (optional) Change the 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 cold milk, warm milk or frothed milk? When adding cold milk or warm frothed milk to a coffee, the temperature of the beverage will decrease to some extent in both cases. This is normal behaviour. Did you pre-heat the cups? Pre-heat the cups with warm water or use a cup heater. The 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 from the coffee, lowering the temperature of the coffee in the cup. Did the temperature drop over time? Descale the machine with the Philips/Saeco decalcifier as the internal circuits might be clogged up with scale.
