Breville / Sage Barista Touch ER08: temperature sensor short circuit

ER08 means: Milk jug temperature sensor short circuit detected during operation.

Same code, same fix on the Barista Touch Impress. Everything below applies to both.

Applies to: Barista Touch.

Short answerThe milk jug temperature sensor (NTC) is reading as a short circuit: the board sees near-zero resistance, which a healthy sensor does not produce. Technician sources name water bridging the sensor contacts (a leak or steam at the probe seal) and a failed sensor as the likely causes. Because it happened during operation, heat or steam reaching the connector is a plausible cause. Breville does not publish this code table, so the meaning comes from third-party service tables.

How to fix ER08

  1. Switch off at the wall and unplug. Leave the machine for an hour so any moisture dries, then try again. A short that clears after drying suggests a leak to find.
  2. Dry the milk sensor area on the drip tray and wipe away any milk residue with a dry cloth. Do not take the machine apart.
  3. A technician would replace any leaking o-rings at the boiler fittings and sensor probes; the leak, not the sensor, may be the true fault.
  4. If the code persists after everything is dry, the milk jug temperature sensor (NTC) needs replacing by a technician.
  5. Afterwards, clear the error log and run a full heat-up and a shot to confirm.

The same steps as the list above, cheapest first. Stop as soon as the code clears.

When to stop and call a repairer

If you see scorch marks, smell burning, or the machine trips your GFCI / RCD, stop: that is an electrical fault, not just a sensor.

Worth repairing?Often yes, but Breville does not publish repair costs. If a leak has soaked the control board, get a quote before spending anything.

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.

Questions

What does ER08 mean on the Breville / Sage Barista Touch?

Milk jug temperature sensor short circuit detected during operation.

Can I fix ER08 myself?

DIY difficulty: hard. Switch off at the wall and unplug. Leave the machine for an hour so any moisture dries, then try again. A short that clears after drying suggests a leak to find. Dry the milk sensor area on the drip tray and wipe away any milk residue with a dry cloth. Do not take the machine apart.

Is it worth repairing?

Often yes, but Breville does not publish repair costs. If a leak has soaked the control board, get a quote before spending anything.

When does ER08 typically show up?

Breville / Sage Barista Touchs report ER08 while brewing or steaming. That timing is a useful clue when narrowing the cause.

Can I keep using the machine with ER08 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 ER08 clear on its own?

Rarely. A reset or power cycle is worth one try, but ER08 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.

How reliable is this page?Breville and Sage do not publish a table of error codes for these machines in the documents we found. The meanings on this page come from third-party repair references and owner reports, so treat them as lower confidence. If your machine shows a text alert, follow the on-screen text first.
