Cytometer indicators: Ready status Fluid level Sample flow Optical Design - Resolution and Sensitivity. To achieve maximum sensitivity and resolution, the generation, preservation and detection of light is critical.
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.
Poor optical alignment / low signal / high CV
HighSymptoms: Bead CVs out of spec, scatter or fluorescence signal low or noisy, compensation drift.
Root cause: Flow-cell contamination or an air bubble, laser degradation / misalignment, or an optics / PMT fault.
Fluidics / sheath-pressure fault
MediumSymptoms: Unstable event rate, boost / prime failures, sheath or waste alarm, clogs.
Root cause: Sheath / waste tank issue, a peristaltic / vacuum fault, or a partially blocked sample line / flow cell.
Sample probe / SIP clog or crash
MediumSymptoms: No or low event rate, probe-position error, carryover.
Root cause: Clogged or bent sample probe, or a clot.
Laser fault
MediumSymptoms: A laser-line-specific parameter fails, laser-error message.
Root cause: Laser at end of life or a power-supply / interlock fault.
Workstation / software fault
LowSymptoms: Acquisition hangs, data will not export, instrument not recognised.
Root cause: Workstation PC or the acquisition software / link.

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: Poor alignment / low signal / high CV
- Run the daily startup / cleaning and a flow-check bead panel.
- Prime / de-bubble the flow cell and de-gas the sheath.
- Run an unclog / long-clean cycle.
- Verify each laser-line parameter against the beads.
- Escalate a confirmed laser or optics fault to the OEM.
Symptom: Fluidics or probe fault
- Check the sheath and waste tanks and connections.
- Inspect the sample probe for a bend or clog and clear it.
- Replace worn peristaltic pump tubing and the sheath filter.
- Run a boost / prime.
- Confirm a stable event rate on a control.
