Frequently Asked Questions

Why is my Breville Sage machine not holding temperature?

Temperature that drops quickly points to scale on the boiler or a failing thermostat. Scale builds up inside every coffee machine and eventually blocks the boiler and pipes. Run a full descaling cycle with Breville Sage's approved descalant every 2-3 months (or whenever the machine prompts it), then rinse with fresh water. If your machine refuses to descale, see our Not Holding Temperature guide.

My Breville Sage Barista Express loses heat quickly — what's wrong?

The quickest way to fix scale problems on a Breville Sage is a full descaling run: use the approved descalant, follow the machine's cycle, and finish with two rinse brews. Repeat every 2-3 months, or as soon as the alert appears. Step-by-step instructions are in our Not Holding Temperature guide.

How do I fix temperature loss on a Breville Sage coffee machine?

If a Breville Sage has not been descaled for a while, limescale restricts the boiler and pipes. Buy the brand's descalant, run the descale program, rinse thoroughly, and schedule it every 2-3 months from now on. See our Not Holding Temperature guide for the full routine.
