Same code, same fix on the Barista Touch Impress. Everything below applies to both.
Applies to: Barista Touch.
How to fix ER10
- Switch the machine off at the wall, wait 60 seconds and switch it back on. A one-off reading glitch clears; a real open circuit comes straight back.
- Reaching the inline (brew water) temperature sensor (NTC) plug means opening the machine, which is technician work. A technician would check that plug on the control board for corrosion or heat marks and test the sensor circuit. Tell them the code you see.
- Look under and around the machine, from the outside, for water trails. Moisture on a connector can read as an open or short circuit; a technician would find and fix the leak behind it, often a boiler o-ring or hose clip.
- If the code returns, the inline (brew water) temperature sensor (NTC) or its wiring needs replacing by a technician.
- Afterwards, clear the stored error (see how to read the error log below) so you can tell whether it recurs.
When to stop and call a repairer
Stop and book service if you see water leaking, a burning smell or any scorch marks. Do not open the machine yourself.

How to check the error log
Switch the machine off at the wall. Hold the front Power button, switch the wall power back on and release when the logo appears. Enter the service password 00000, then open Error Counter to see stored faults or Live Debug for live temperatures.
Clear the log after a repair so you can tell whether the fault has really gone.
Beyond the fix
Tips and tricks
- Do not open the machine yourself. The manual says to leave anything beyond cleaning to Breville support or an authorized servicer, because these parts sit next to mains wiring.manufacturer manual

Questions
What does ER10 mean on the Breville / Sage Barista Touch?
Inline temperature sensor open circuit detected during operation. The control board cannot read the inline (brew water) temperature sensor (NTC). On this code the sensor reads as an open circuit: the wire has come off, the plug is loose or corroded, or the sensor itself has failed. Because it dropped out mid-cycle, a loose or heat-damaged connection is the most likely cause. Breville does not publish this code table, so the meaning comes from third-party service tables.
Can I fix ER10 myself?
DIY difficulty: hard. Switch the machine off at the wall, wait 60 seconds and switch it back on. A one-off reading glitch clears; a real open circuit comes straight back.

Is it worth repairing?
Often yes for a single sensor, but Breville does not publish repair costs. Get a quote first, especially on an older machine.
When does ER10 typically show up?
Breville / Sage Barista Touchs report ER10 while brewing or steaming. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with ER10 showing?
Usually you can finish the drink you are making, but do not ignore it — the underlying fault rarely heals itself. Work through the cheap checks first.
Will ER10 clear on its own?
Rarely. A reset or power cycle is worth one try, but ER10 with a "hard" difficulty rating almost always means a failed component that has to be replaced.
How long does the repair take?
This one is a bench repair for most owners — the teardown, test and reassembly are the bulk of the work, not the part itself.
