Same code, same fix on the Oracle. Everything below applies to both.

How to fix ER24
- Tank full and seated, then power cycle and let the machine attempt a fill.
- Descale as the manual describes, including the steam boiler cycle if your model has one. Technician sources say scale on a level probe can read as "no water".
- Some service menus show a live boiler level reading while the pump runs. A technician would use it to see whether the probes register water.
- Cleaning the probes, replacing their o-rings and checking the inlet hose means opening the machine and working near mains voltage, so it is technician work.
- If the fill pump buzzes and no water reaches the boiler, a technician would check the pump.
Descale as the manual describes and restart once. If the code returns, contact Breville or an authorised service centre and give them the code; checking probes means opening the machine and is technician work.
When to stop and call a repairer
Water and mains electricity share the top of the boiler. Do not open the machine or touch the probes.

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 (stored faults) or Live Debug (live temperatures and water levels). One technician video says the entry method differs between machines built before and after 2018, so if this does not work, do not keep trying.
Clear the log after a repair so you can tell whether the fault has really gone.
Beyond the fix
Tips and tricks
- Use the machine's descale cycle on schedule and do not remove or empty the tank during it.manufacturer manual
- Clear the stored error in the service menu and restart; if it returns, a technician should check the probes and connections.technician video
Common mistakes
- Assuming a level probe fault always means an empty tank; probes can misread through scale or residue.
Easily confused with
- Our page lists ER21 as the steam boiler high level probe fault. The sources we read describe probes only in the steam boiler, so confirm which boiler is meant before ordering parts.

Questions
What does ER24 mean on the Breville / Sage Oracle Touch?
Coffee boiler level probe fault (unconfirmed; probes are documented on the steam boiler). The boiler water-level probe is not reporting what the controller expects: the boiler should be filling and the level probes should register water, and they do not. Scaled probes, a blocked inlet line, a fill pump that has stopped moving water, or a probe seal leak are the causes technician sources describe. Breville does not publish this code table, so the meaning comes from third-party service tables. ER24 is listed in third-party tables as a coffee boiler water level probe fault. We could not confirm that mapping: the technician videos we read describe the three level probes (high, low and ground) in the steam boiler, not the coffee boiler, and older and newer Oracle Touch units may differ.
Can I fix ER24 myself?
DIY difficulty: hard. Tank full and seated, then power cycle and let the machine attempt a fill. Descale as the manual describes, including the steam boiler cycle if your model has one. Technician sources say scale on a level probe can read as "no water".

Is it worth repairing?
Often yes, but Breville does not publish part or repair costs. Ask for a quote.
When does ER24 typically show up?
Breville / Sage Oracle Touchs report ER24 any time. There is no reliable pattern to when it appears — treat any occurrence as real.
Can I keep using the machine with ER24 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 ER24 clear on its own?
Rarely. A reset or power cycle is worth one try, but ER24 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.
