Sage High Brew Temperature or Over-Extraction

Coffee tastes bitter or burnt even with correct grind and dose

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Brew temperature set too high, Faulty temperature sensor reading low, Excessive shot time, Scale affecting flow

Safety: Avoid touching hot metal surfaces.

Adjust brew parameters:
- Use a slightly coarser grind and reduce shot time to 25–30 seconds.
- Reduce brew temperature setting if your model allows.
Descale: Run a descale cycle to normalize flow and temperature control.
Monitor temperature: If coffee remains excessively hot or burnt-tasting, the sensor may be misreading.
Repair (advanced): Replace the brew thermistor sensor if it is out of calibration, or the main control board if it is driving the heater incorrectly.
