Your Sage won’t heat up
If the machine lights up but doesn’t heat, or the coffee is lukewarm, it is most often a sensor, a thermal fuse or the heating element.
What you can check yourself
- Make sure there is water in the tank and that the tank is seated properly. Some models stop heating without water.
- Preheat the cup and portafilter by running water through first. A cold cup and a cold portafilter give lukewarm coffee.
- Check the temperature setting on models with a display (Barista Pro, Touch, Oracle, Dual Boiler).
Tip: Unplug the machine before you clean it or take parts off. If it needs opening, leave that to us.
Typical causes when the checklist doesn’t help
Thermal fuse
A fuse by the heating element blows if it gets too hot. It doesn’t come back by itself and has to be replaced.
Faulty heating element or thermocoil
The machine turns on but never gets hot.
Temperature sensor
The machine thinks it is hot enough, or too hot, and stops heating.
Control board fault
The controls don’t send power to the heating element.
When does it need repairing?
If that doesn’t help, it needs a repair. Heating faults mean opening the machine, which shouldn’t be done at home.

Why is my espresso lukewarm?
Most often because the cup and portafilter are cold, or the machine hasn’t had a few minutes to warm up. If it’s still lukewarm, it can be a sensor.
