Breville & Sage Error Codes & CLEAN ME Light Explained

Marco R. By Marco R. · Lead repair technician Updated June 18, 2026
The CLEAN ME light and controls on a Breville Barista Express

Breville machines (sold as Sage in the UK and Australia) mix a few signal types: the famous CLEAN ME light, button flash patterns, and numbered ER codes on the more advanced models. Most are routine — a clean, a reset, or a descale — and only a persistent ER code points to a real fault. This guide covers the Breville/Sage language across the Barista and Bambino range; for exact steps, see the model guides.

CLEAN ME: run the flush cycle

The CLEAN ME light counts shots and asks for the machine’s cleaning cycle — a backflush-style flush using the supplied cleaning disc in the portafilter plus a Breville cleaning tablet. It targets coffee oils, not scale, so you still descale separately. Run it when prompted and the light clears. (More on cleaning: cleaning guide.)

All lights flashing / overheating

On start-up, flashing lights are just heating — wait. If they keep flashing and it won’t brew, it’s usually an overheat or fault:

  1. Turn off and unplug for 60 seconds.
  2. Make sure the tank is full and seated.
  3. If it’s been working hard, let it cool first.
  4. Restart.

ER codes

The advanced models show numbered ER codes when they detect a fault and stop. First step for any ER code is a full reset (off, unplug a minute, seated parts, restart); cool it if it overheated, and descale if due. If a specific code returns, note it and contact Breville/Sage support — it points to a component fault.

Common mistakes

  • Treating the start-up flash as a fault.
  • Confusing CLEAN ME with descaling — they’re different cycles.
  • Skipping the cleaning disc/tablet for the CLEAN ME flush.
  • Restarting a hot, overheated machine without letting it cool.
  • Ignoring a returning ER code instead of contacting support.

Frequently asked questions

What does the CLEAN ME light mean on a Breville?
It means the machine has counted enough shots to need its cleaning (backflush-style) cycle. Run it with the supplied cleaning disc in the portafilter and a Breville cleaning tablet, following your model's flush procedure. The light clears once the cycle completes. It's about coffee oils, not scale — you still need to descale separately. Ignoring CLEAN ME lets oils build up and turns shots bitter.
Why are all the lights flashing on my Breville Barista Express?
All lights flashing on start-up is usually just the machine heating — wait for them to settle. If they keep flashing and it won't brew, it's typically an overheat or a fault: turn it off, unplug for 60 seconds, make sure the tank is full and seated, and restart. If it overheated from heavy use, let it cool first. A reset clears most flashing-light states; a persistent one points to a fault.
What do ER codes mean on a Breville / Sage machine?
An 'ER' (error) code indicates the machine has detected a fault and stopped. The first step for any ER code is a full reset: power off, unplug for a minute, ensure the tank and parts are seated, and restart. Some ER codes relate to overheating (let it cool) or sensors. If a specific ER code returns after a reset and a descale, note the exact code and contact Breville/Sage support, as it points to a component fault.
Why does my Breville flash the filter / single-cup light?
On the Barista range, a flashing single- or double-cup button during a shot usually means you're in volume-programming mode — hold the button and release at the volume you want to set it. Some models also prompt about the water filter or grind. If lights flash in a pattern you don't recognise, check your model guide; most are programming or maintenance prompts, not faults.
How do I reset a Breville espresso machine?
Turn it off and unplug it for about 60 seconds, then restart with the tank full and seated and the portafilter/tray in place. That clears most flashing-light and transient ER states. If it overheated, let it cool 20–30 minutes first. For volume or settings oddities, you can also re-program the shot volumes. A fault that survives a reset and descale needs Breville/Sage service.
