What This Guide Helps With
Identifies causes of inaccurate temperature readings, preventing failed sterilization cycles and ensuring instrument and patient safety.
Step-by-Step Troubleshooting
Ensure Staff Safety
Confirm the sterilizer chamber is not pressurized and no personnel are near the door. Avoid burns or injury during inspection.
Check Display and Error Messages
Review the control panel for temperature error codes or warnings. Note any unusual readings. This indicates if calibration drift or sensor failure is suspected.
Verify Power Stability
Ensure the sterilizer is plugged into a reliable outlet with stable voltage. Fluctuations can cause false temperature readings.
Inspect Sensor Connections
Check the wiring and connectors to the temperature probe. Loose or corroded connections can cause inaccurate readings. Expected outcome: secure connections without damage.
Compare Against External Thermometer
If safe, run a short test cycle using a calibrated external thermometer or temperature probe. Confirm the sterilizer’s reading matches the external measurement within tolerance.
Reset Calibration (if supported)
Some Elara models allow a software recalibration or reset of the temperature sensor. Follow manufacturer prompts and verify that readings stabilize afterward.
Observe Next Cycle
Run a monitored cycle to ensure temperature reaches and maintains the set point. If stable, the issue is resolved.
If the Problem Persists
External causes have been ruled out. The temperature sensor or internal electronics may be faulty. The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
Knowing when to stop avoids risk and ensures patient safety.
Clinical Use Tip
Do not attempt patient sterilization if temperature readings are inconsistent. Move instruments to another functioning sterilizer until the Elara unit is verified.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Sterilizer displayed fluctuating temperature readings during cycle."
Cause
What was observed during troubleshooting.
Example:
"Loose sensor connection and minor calibration drift identified."
Resolution
What action was taken.
Example:
"Secured sensor, performed recalibration, verified proper temperature readings during test cycle."
Helpful Details to Include (If Known)
- Outlet tested and stable
- Sensor wiring inspected
- Control panel error codes recorded
- External thermometer validation
- Device status after recalibration
Final Thought
Accurate temperature measurement is critical for effective sterilization. Follow logical troubleshooting from simple external checks to controlled calibration, escalating appropriately, and document thoroughly.
That is successful troubleshooting.
