Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Centrifuge imbalance / bearing
HighSymptoms: Vibration, loud noise, stop error.
Root cause: Worn bearing or unbalanced rotor.
Reagent / wash flow fault
MediumSymptoms: Clogs, high blank, QC fail.
Root cause: Pump tube wear, air in line.
Temperature control fault
MediumSymptoms: Incubator out of range.
Root cause: Failed heater/fan or sensor.
Optics / lamp degradation
LowSymptoms: Low signal, wavelength drift.
Root cause: Lamp/LED or monochromator aging.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Sample probe / pipette clog
- Confirm the presentation - typically aspiration error, short sample, carryover - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: clot/crystal obstruction.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the sample aspiration probe per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Reagent / wash flow fault
- Confirm the presentation - typically clogs, high blank, QC fail - and note the exact alarm or message and the conditions when it occurs.
