Breville / Sage Oracle Touch ER20: boiler water level or pump fault
ER20 means: Steam boiler water level or pump issue detected.
How to fix ER20
- Tank full and seated, then power cycle and let the machine attempt a fill.
- Descale, including the steam boiler cycle if your model has one. Scale on the level probe is insulating and reads as "no water".
- Use the service mode Live Debug screen to watch the boiler level reading while the pump runs.
- Open the machine and clean the probes with a scale remover, replace their o-rings, and check the inlet hose for blockage.
- If the fill pump buzzes and no water reaches the boiler, replace the small pump. Some owners top the boiler up with a syringe through the probe port to get the machine running while parts are on order.
Descale, clean the probes and replace their o-rings; then check the fill pump actually moves water. Some owners syringe water into the boiler through the probe port to get going.
When to stop and call a repairer
Water and mains electricity share the top of the boiler. Unplug before touching the probes.
What it costs
Parts: Level probe and o-ring kit about $85; steam boiler fill pump $30 to $60.
Service: Out-of-warranty Breville service quotes for internal faults are commonly $300 to $500, sometimes more, plus shipping. Independent espresso repair shops are usually cheaper for a sensor swap.
Worth repairing? Yes. Probes, o-rings and a fill pump are all under $100 and this is the single most common Breville dual-boiler repair.
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).
Clear the log after a repair so you can tell whether the fault has really gone.

FAQ
What does ER20 mean on the Breville / Sage Oracle Touch?
Steam boiler water level or pump issue detected. The steam boiler and its pump 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, an inlet line blocked with scale, a small fill pump that has stopped moving water, or a probe seal leak all produce this code. ER20 is a steam boiler level or pump issue: the boiler called for water and the level probes never saw it arrive. Scaled probes and a tired fill pump are the two causes.
Can I fix ER20 myself?
