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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Aperture / flow-cell blockage or partial obstruction
HighSymptoms: Flagged or implausible CBC counts, voteouts, clog alarms, poor precision.
Root cause: Debris or a clot partially blocking a counting aperture or the flow cell.
Sample probe / piercer / valve wear
MediumSymptoms: Short samples, aspiration errors, cap-piercing failures, carryover.
Root cause: Worn or bent sample probe / closed-vial piercer, or a worn shear / segment valve.
Reagent / lyse delivery fault
MediumSymptoms: WBC, HGB or diff results shifted, high background, reagent alarms.
Root cause: Reagent depleted or wrong lot, or a pinch-valve / tubing fault.
Optics / laser fault (diff)
MediumSymptoms: Diff scattergrams abnormal, missing populations, flow-cell or laser alarm.
Root cause: Contaminated or aged flow cell, or the laser / optics.
Vacuum / pressure out of range
MediumSymptoms: Multiple parameter errors, priming failures.
Root cause: Pump or regulator drift.

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 starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Clog alarm or flagged counts
- Run the instrument's aperture / flow-cell clear and flush cycles.
- Run a background count and confirm it is within limits.
- Run controls at all levels.
- Clean or replace the aperture bath / flow cell if clogs recur.
- Confirm precision on a replicate sample before releasing results.
Symptom: Short samples or aspiration errors
- Inspect the sample probe / piercer for wear or a bend.
- Check the shear / segment valve and tubing for leaks or wear.
- Verify vacuum and pressure against the service spec.
- Replace the probe / piercer, valve or tubing as found.
- Re-run controls.
