Breville / Sage Oracle Touch ER23: flow meter signal problem
ER23 means: Flow meter signal problem during brewing.
How to fix ER23
- Fill and firmly reseat the water tank. Run the hot water outlet for 30 seconds and then the brew button with no portafilter to purge air.
- Descale if it has been more than three months. Scale on the flow meter paddle is the single most common cause.
- Remove the portafilter and run water through the empty group head. Good flow here but a code with coffee in means the grind or basket is the blockage, not the meter.
- Listen to the pump. A loud buzz with no water means a dry or failing pump or a blocked inlet; a silent pump means no power to it.
- Open the machine and inspect the flow meter (a small plastic body on the tank-side hose). Flush it, clear debris, and reseat its two-wire plug. Replace if the paddle is stuck.
Run water through an empty group head. Good flow means grind and basket, not the machine. Weak or no flow means descale first, then flow meter, then pump.
The coffee pump on the Oracle Touch is a standard vibratory pump, around $30 to $60, and is the part most often replaced for a persistent ER23.
When to stop and call a repairer
If the pump runs but water leaks inside the machine, stop and find the leak first.
What it costs
Parts: Flow meter $20 to $40; pump $30 to $60; descaler $10.
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. Descaling fixes most of these for the price of descaler; a flow meter or pump is cheap.
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 ER23 mean on the Breville / Sage Oracle Touch?
Flow meter signal problem during brewing. The machine expects pulses from the flow meter while the pump runs and is not seeing them during brewing. Either no water is moving (empty or unseated tank, airlock, blocked path, tired pump) or water is moving and the flow meter cannot count it (scale or debris on its little paddle wheel, or a failed sensor). ER23 is a flow meter signal problem during brewing: the coffee pump is running but the flow meter is not counting water. Most often the pump has weakened or the flow meter paddle is scaled; sometimes the coffee is simply ground so fine that nothing moves.
