🔧 Product Overview

The steam probe set is a critical internal sensor assembly used in Breville Dual Boiler and Oracle espresso machines. It monitors water levels inside the steam boiler and communicates with the control board to regulate filling, heating, and safety functions.

In Australia’s hard water conditions, these probes are a known high-wear service item. Over time, scale buildup, ceramic coating wear, seal failure, or internal leakage can cause incorrect readings and machine faults.

Replacing the probe set with this genuine Breville OEM part restores accurate operation and prevents costly boiler or electronic damage.

🔧 Common Faults This Part Fixes

1. Worn or Damaged Ceramic Coating

Heat, pressure, and chemicals degrade the ceramic layer over time.

👉 Causes:

• Incorrect boiler level detection

• Unstable machine operation

• Sensor reading failures

---

2. Scale Buildup (Very Common in Australia)

Hard water causes limescale deposits on probes, affecting accuracy.

👉 Symptoms:

• “Fill Tank” warning when tank is full

• Boiler overfilling or not filling correctly

• Irregular heating cycles

---

3. O-Ring and Seal Deterioration

Seals harden or crack due to heat and pressure.

👉 Symptoms:

• Steam leaks inside machine

• Hissing noise during heating cycle

• Moisture around probe area

---

4. Internal Probe Leakage

Internal failure allows water to pass through probe body.

👉 Symptoms:

• Persistent leaks even after seal replacement

• Corrosion or moisture near probe housing

---

5. Sensor Failure / Incorrect Readings

Electrical degradation causes false signals to control board.

👉 Results:

• Boiler overfilling

• Heating instability

• Unexpected shutdowns

---

6. 🔥 Hissing Noise When Heating Above 80°C (Common Fault)

A key early warning sign of probe failure or scale-related issues.

👉 Symptoms:

• Audible hissing noise inside machine during heating

• Occurs when temperature reaches ~80°C or higher

• Pressure escaping due to faulty sensing or internal leakage

• Often linked to scale buildup or seal failure

👉 Result:

• Unstable steam pressure

• Reduced machine performance

• Risk of further internal damage

---

7. Regular Maintenance Requirement

Recommended replacement every 2–3 years or during major servicing.

👉 Why:

• Prevent unexpected failure during descaling

• Avoid expensive boiler or PCB damage

• Maintain safe pressure and temperature control

---

🛠️ Common Issues This Part Fixes

• Boiler overfilling

• “Fill Tank” message when tank is full

• Internal steam leaks

• Hissing noise during heating cycle

• Sensor error codes

• Machine shutdown or heating instability

❓ Frequently Asked Questions

Will this fit my Breville machine?
Yes — compatible with BES920, BES980, and BES990 models.

Why is my machine making a hissing sound?
This is commonly caused by failing or scaled steam probes affecting pressure and sensing accuracy.

Can I clean instead of replacing?
Descaling may help temporarily, but worn or leaking probes require replacement.

How often should this part be replaced?
Typically every 2–3 years or during scheduled servicing.

Is this a genuine Breville part?
Yes — this is an original OEM replacement part.
