The Breville / Sage Barista Touch Impress shows this code with identical meaning and fix as the Barista Touch. Full guide for ER05.
Applies to: Barista Touch Impress.
How to fix ER05
- 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.
- Look at the milk jug sensor area on the drip tray. With the machine off and cool, wipe away any milk residue or debris around the sensor with a dry cloth and let it dry. Do not take the machine apart.
- 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 milk jug 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.
With the machine off and cool, wipe the sensor area on the drip tray clean and dry. If the code returns, contact Breville or an authorised service centre. We have not confirmed that a BES880 sensor part fits the Impress, so ask before buying one.
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.

| Worth repairing? | Often yes for a single sensor, but Breville does not publish repair costs. Get a quote first, especially on an older machine. |
How to check the error log
Unplug the machine. Press and hold the Power button while plugging it back in. When the password screen appears, enter 02015 to open Service Mode, then open the error log.
Clear the log after a repair so you can tell whether the fault has really gone.
Beyond the fix
Tips and tricks
- Place the jug straight down onto the sensor rather than knocking or sliding it across. A repair shop explains the probe moves each time a jug lands, and repeated knocks wear the thin wire underneath.technician video
- A new sensor kit fixes a broken wire, but the video shows the base opened and the sensor board removed. That needs a qualified technician, who would also glue the new sensor in place.technician video
Common mistakes
- Bypassing the sensor with a homemade resistor, as one owner video does with pencil lead. It removes milk temperature sensing and involves opening the machine.
Easily confused with
- ER05 to ER08 all point at the same milk sensor circuit: open or short, at startup or during use. The mix of codes shown does not mean separate faults.

Questions
What does ER05 mean on the Breville / Sage Barista Touch Impress?
Milk jug temperature sensor open circuit detected at startup. The control board cannot read the milk jug 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 fails the self-test at power-on, the machine refuses to start until the sensor reads again. Breville does not publish this code table, so the meaning comes from third-party service tables. ER05 on the Barista Touch Impress is listed as the milk jug temperature sensor failing its startup self-test, as on the Barista Touch BES880. Breville publishes no code table, so treat the meaning as third-party.
Can I fix ER05 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. Look at the milk jug sensor area on the drip tray. With the machine off and cool, wipe away any milk residue or debris around the sensor with a dry cloth and let it dry. Do not take the machine apart.

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.
ER05 during startup or during use?
Breville / Sage Barista Touch Impresss report ER05 during the power-on self-test. That timing is a useful clue when narrowing the cause.
Can I keep using the machine with ER05 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 ER05 clear on its own?
Rarely. A reset or power cycle is worth one try, but ER05 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.
