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.

Error Codes
Extracted directly from this unit's own service manual.
W-CLWBC Clog Error
1. Check the lyse reagent to be sure it is not empty or expired. 2. Check the lyse tubing connection to the WBC counting chamber. 3. Check the wires attached to the WBC counting chamber to be sure they are connected.
R-CLRBC Clog Error
1. Perform Back Flush. 2. Perform Clean. 3. Perform a Shut Down and then a Start Up. 4. Check the wires attached to the RBC counting chamber to be sure they are connected. 5. Perform Bleach Clean.
HGBNo results
1. Run a Start Up Cycle.
Rejected results---- *
1. Be sure the right side door is closed. 2. Run a Start Up cycle.
PLTImprecise or Inaccurate results
1. Perform Back Flush. 2. Perform Clean. 3. Perform Bleach Clean. 4. Verify reagent connections.

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 / aperture / flow-cell alarm or flagged CBC counts
- Run the instrument's aperture / flow-cell clear (burn / back-flush) 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 / aspiration errors / carryover
- Inspect the sample probe / closed-vial piercer for wear or a bend.
- Check the shear / segment valve and the 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 and a carryover check.
Symptom: WBC / HGB / diff shifted / high background
- Confirm reagents and lyse are in date, primed and the correct lot.
- Check the pinch valves and tubing for wear or air.
- Run the fluidics prime and a background count.
- Recalibrate if the shift is confirmed against controls.
- Escalate an optics / laser fault if scattergrams are abnormal.
Symptom: Autoloader / transport jam
- Clear the jammed tube / rack and note where it hangs up.
- Inspect the autoloader belt, gripper and mixing station.
- Check the rack sensors.
- Cycle several racks.
- Replace the belt / gripper as found.
